Troubleshooting for Nokia N8-00

To lock or unlock the touch screen and keys, slide the lock switch (on right side of device).

When playing stereo audio with Symbian^3 devices to headsets or accessories with an own amplifier, the volume is controlled in the accessory. The volume keys in the phone can in this situation be used only for muting the audio but not for the volume control.

Note that the volume bars on the phone may still keep changing when using the phone volume keys but the actual volume is controlled only by the volume keys in the accessory.

Your Nokia device requests PIN (Personal Identification Number) and PUK (Personal Unblocking Key) codes to protect your SIM card and device against unauthorized use. Note that all PIN and PUK codes are provided by your network operator. Nokia is not able to provide you PIN or PUK codes.

Please note the following:

• When your insert your SIM card and boot up your device for the first time, you need to enter the PIN code. For security reasons it is recommended to change it to your own code, instructions on how to change the PIN code in your device is provided in the user guide or Nokia web site. If the PIN code is entered incorrectly multiple times, your device may request a PUK code to futher validate the user's identity and to unlock and change the blocked PIN code.
• The PIN2 code is a PIN code which acts as a second layer of protection for certain features of your phone.  If the PIN2 code is entered incorrectly multiple times, your phone may request a PUK2 code.

If you have forgotten or simply do not know the codes, you must contact your Network Operator for assistance. However, if you have already contacted but the code does not work, you should consider getting a new SIM card from your Network Operator.

PIN (Personal Identification Number) codes:
- PIN code protects your SIM card against unauthorized use. It is asked when you insert the SIM card and boot up the device for the first time. It is from 4 to 8 digits long and usually supplied with your SIM card. However, it is recommended to change the original PIN code to your own, the instruction on how to change the PIN code is provided in the user guide or Nokia Web site. 
- PIN2 code is also 4 to 8 digits long and is supplied with some SIM cards, and is required to access certain services.
- If you enter any of the above PIN codes incorrectly three consecutive times, you need corresponding PUK codes to unlock them. Read more about PUK codes below.

PUK (Personal Unblocking Key) codes:
- PUK code is 8 digits long and is required to change a blocked PIN code.
- PUK2 code is required to change a blocked PIN2 code.
- The PUK codes are also provided by your network operator.

Restriction code / Restriction password:
- The restriction code or restriction password may be required when using some network services, such as call restriction service. Note that not all network operators support such service.
- If your device display "Enter restriction code" when you insert a new SIM card, it means that your device has been locked to use a certain operator's network and it does not accept SIM cards from other operators.
- Contact your network operator for assistance.

Other PIN codes:
- The module PIN is required to access the information in the security module of your SIM card.
- The signing PIN may be required for the digital signature. 
 
Important! If you do not know or you have forgetten any of these codes above, always contact your network operator. Keep all the codes in a safe place separate from your phone.

Lock code / Security code / Password:
- These codes protect your phone from unauthorised use.
- The default lock code or security code supplied with the phone is usually 12345. For Nokia N9 and Lumia devices there are no default codes. It is recommended to specify the code of your own. The instruction on how to change the code is provided in the user guide.
- If you get error notifications after entering the code too many times incorrectly, reboot the phone and wait for 15 minutes, then try again.
- If the problem persists, contact your local Nokia Care Point. The contact information can be found from your local Nokia support web pages.

PAC (porting authorisation code) code:
- This code is used by some mobile network operators to facilitate mobile number portability. The code allows you to transfer your existing mobile phone number from one mobile phone network provider to another mobile phone provider so that if you change mobile phone networks you do not have to give everyone a new number. You can keep your existing mobile phone number.

These kind of messages are displayed in the following situations:

• The SIM card may be out of alignment. If the phone has recently been dropped, bumped, or opened, the SIM card may need adjusting. Follow the SIM card installation instructions in your phone user guide.
• The PUK (Personal Unblocking Key) code is entered incorrectly multiple times. This can inactivate the SIM card. If inactivation appears to be permanent, contact your operator or service provider for a new SIM card.
• You have recently changed your mobile operator or mobile service provider. In this case, either your SIM card or your phone settings may have been configured for your previous operator and therefore reconfiguring is needed.
• It may also be that your phone is simlocked, so using a SIM card from a different operator or service provider is prohibited. Please contact your current mobile operator or service provider for further assistance.

If none of the situations above apply and you continue to receive this error message, your SIM card may be damaged. Please contact your mobile operator or service provider. Or alternately, contact your local Nokia Care Point for inspection.

Many features in your Nokia N8 device increase the demand on battery power and reduce the battery life time. To save battery power, note the following:

1. Always charge the battery fully (until the battery full notification is seen or the battery status bar stops running and stays in full position and charging indicator light is off).
2. Activate power saving mode. Press the power key, and select Activate power saving.
3. Change the synchronisation frequency for your mailbox. Select Menu > (Applications) > Mail, your mailbox, and  Options > Settings, and the relevant sync frequency settings.
4. Mute unnecessary tones, such as key tones.
5. Use wired headphones, rather than the loudspeaker.
6. Deactivate the background animation effects. Select Menu > Settings >Themes > General > Options > Theme effects > Off.
7. Deactivate the Big clock screen saver. Select Menu > Settings > Themes > Screen saver > None.
8. Features that use Bluetooth technology, or allowing such features to run in the background while using other features, increase the demand on battery power. To prolong the operating time of your device, turn the Bluetooth technology off when you do not need it (Menu > Settings > Connectivity > Bluetooth > Bluetooth = Off).
9. Features that use wireless LAN (WLAN, Wi-Fi) increase the demand on battery power. WLAN on your Nokia device switches off when you are not trying to connect, not connected to another access point, or not scanning for available networks. To further reduce battery consumption, you can in Symbian Anna and earlier specify that your device does not scan, or scans less often, for available networks in the background. WLAN switches off in between background scans. When Menu > Settings > Connectivity > WLAN > Options > Settings > Show WLAN availability is set to Never, the WLAN availability icon is not shown in the standby mode. However, you can still manually scan for available WLAN networks and connect to WLAN networks as usual.
10. If you have set Packet data connection (or Mobile data connection) to When available in connection settings, and there is no packet data coverage (GPRS), the device periodically tries to establish a packet data connection, which causes increased demand on battery power. To prolong the operating time of your device, select Menu > Settings > Connectivity > Admin.settings > Packet Data (Mobile Data) > Packet data connection (Mobile data connection) > When needed. 
11. The Maps application downloads new map information when you scroll to new areas on the map, which increases the demand on battery power. You can avoid the automatic downloading of map data by downloading the needed map data via PC to your device.
12. If the signal strength of the cellular network varies much in your area, your device must scan for the available network repeatedly. This increases the demand on battery power. If the network mode is set to dual mode in the network settings, the device searches for the UMTS network. If it is not available, the device uses the available GSM network. To only use the GSM network, select Menu > Settings > Connectivity > Network > Network mode > GSM.
13. The backlight of the display increases the demand on battery power. To change the timeout after which the backlight is switched off, select Menu > Settings > Phone > Display > Light time-out. To adjust the light sensor that observes the lighting conditions and adjusts the brightness of the display, in the display settings, select Light sensor or Brightness.
14. The notification lights can be turned off to save the battery. Select Menu > Settings > Phone > Notification lights and disable the breathing light in Breathing light (or Standby breathing light) and adjust the light settings for different events in Notification light menu.
15. Leaving applications running in the background increases the demand on battery power. To close the applications you do not use, press and hold the menu key, swipe to the application in the list and close it by selecting X.
16. Pay special attention that you don't leave applications running in the background which are using GPS or network connection, for example Maps, if you are not using these applications.
17. Home screen widgets may periodically connect to internet if the home screen is in online mode. If you are not actively using the widgets, the automatic connection can be disabled by selecting Options > Widgets to offline mode on the home screen (Symbian Anna and earlier).
18. Installed 3rd party applications may consume extra power. Uninstall the application if you have noticed that power consumption has increased after the application was installed and if the application is not needed any more.
19. The AMOLED display in your device consumes more power with white color. Therefore the themes with a lot of white colors (e.g. in wallpaper image) may consume more power than the other themes.
20. When connecting to the internet, use a WLAN connection, rather than a packet data (GPRS or 3G) connection.
21. When you are listening to music, and do not want to make or receive calls, activate the offline profile..

It is recommended that you use the Nokia battery charger (AC-15) that was included in the sales package of your Nokia device. This charger is optimized for your Nokia device's battery.

Your device (e.g. Nokia N8-00, C6-01, C7-00, E7-00) has a proximity sensor which detects when the phone is close to your ear during a phone call and automatically locks the touch screen to avoid unintended actions, e.g. ending the call by mistake. The proximity sensor is located in the top right corner of the device (on the left side of the light detector and front camera).

If the touch screen is not properly locked during a call, check the following:

• Check that there is no protective foil tape covering the touch screen which could affect the sensitivity of the proximity sensor.
• Keep the phone tightly to your ear when you are having a call. Proximity sensor is designed to detect contact from a distance of up to 10 mm and having the phone tightly to your ear will improve the sensor functionality.
• Do not move the phone during the call. Shifting the phone upwards or moving the upper side farther away from your ear might expose proximity sensor for light and could open the key lock.
• If needed, use the key lock switch during the call. Turn the key lock on by using the key lock switch after you have answered the call. This will force the touch screen to be locked and moving the phone away from your ear during the call will not open the key lock.

With phone software versions before Symbian Anna, the accented and special characters can be found by long pressing the Character Range key (key with label 1* or AB) on the touch screen QWERTY keyboard. Select the desired range of characters in the pop-up menu to view the available special characters.

In Symbian Anna (and later) long press the corresponding base character and select the accented character from the pop-up list.

Depending on the situation, proceed as follows:

A.  Battery runs out (goes flat) in normal use and the phone turns off.

When the charger is connected to the phone and if it seems that the phone:

• does not start to charge (charging bar not running and charging indicator light not lit) or
• is not booting up from power key shortly after the charger was connected.

In this situation, repair the problem in the following way:

1. To boot up the phone: Wait at least 20 seconds (with the charger still connected) and press the power key.
2. To re-charge the battery: Wait at least 20 seconds (with the charger still connected) and re-connect the charger.

B.  The battery has ran out (has gone flat) as the phone has NOT been in use for several days / weeks (i.e. the battery has gone totally empty).

When charger is connected to the phone, it may take several minutes before the charging starts and anything is seen on the screen. Do the following:

1. Charge the phone before trying to start it.
2. In some cases charging may not start when connecting the charger to the phone for the first time. If that happens, disconnect the charger and try again.
3. Check that the charging LED light is lit. If light is seen, then charging works properly.

Applies for Symbian Anna and earlier software releases.

When pressing the power key and selecting Activate power saving, the device settings are optimised to save the power by adjusting e.g. the following settings:

• Network mode changed to GSM.
• Bluetooth turned off.
• WLAN scanning disabled on home screen. 
• Display settings optimised by setting the light sensor value to minimum and shortening the light time-out.
• Theme effects turned off.
• Touch screen vibration turned off.

To deactivate power saving mode, press the power key, and select Deactivate power saving.
