Troubleshooting for Nokia C6-00

A data connection is automatically established when the online mode has been selected in the home screen settings. The home screen widgets can then automatically fetch the latest information from internet and show it on the home screen.

The automatic data connection can be disabled by selecting the offline mode in the home screen settings:

• Select  Options > Content to offline mode

Note that the data connection may be opened automatically also by some other applications, for example by the email clients. The home screen setting doesn't affect the connections opened by these applications.

To disable the automatic email updates, go to email settings and change the synchronisation frequency (e.g. by selecting Sync frequency > Update interval > Manual).

When the device is started up the first time after the purchase, there might occur a "memory full" notification in the display within a few minutes after start up. If this happens, do the following steps to solve the issue:

1. Remove the battery from phone.
2. Re-insert the battery and boot up the device.

If above does not help, reset the device to the factory settings by entering *#7780# in the dial pad. Before the device is reset, you need to provide the device lock code. The default lock code is 12345.

If still the same issue appears, take a backup by Nokia Suite and format the device by entering *#7370# in the dial pad. Before the device is reset, you need to provide the lock code. Resetting the device will permanently erase all user data and settings as well as add-on applications and operator specific settings.

Yes. This client supports the viewing of emails in HTML format. However, users cannot compose and send an email in HTML format.  Also, HTML formatted emails that get smart forwarded from the client are automatically converted into plain text format, so the recipient will not be able to view the email in HTML.

Some Communities (e.g. Nokia chat) have the ability to display additional information from your profile, which can be seen by others who have been added to the contact list. 

From the Community screen, perform the following:

• Tap Options > My Profile.
• Edit the information, and tap Save.

If your device isn't recognized by PC when plugging via USB cable, try the following actions to recover:

1. Check that you are using the original Nokia USB cable and that the cable is properly connected to the phone and PC.
   
2. Disconnect the mobile device and connect it again.
3. Remove the battery, insert it back again and restart your mobile device. In phone models with integrated battery, press the  power button for around 10 seconds
   
4. Restart your PC.
5. Try connecting to another USB port on your PC. Connect the phone directly to your PC instead of connecting e.g. via a USB hub.
   
6. In Symbian devices, try selecting another connection mode in your mobile device (e.g. Nokia Suite/PC Suite, Mass Storage, Media Transfer). Note that when connecting to Nokia Suite, you need to select Nokia Suite/PC Suite mode (check the connection mode in Settings > Connectivity > USB).
   
7. In some Symbian devices, if having copied a large number of files (> 4000 files) in Media Transfer USB mode to the device, the PC connection may not succeed any more. If this happens, try deleting files with File Mgr. application to decrease the number of files below 4000.
8. If running Nokia Suite in the PC, check that the latest Nokia Suite version is installed (check for updates in Nokia Suite Software Updates menu). Check also that your phone is compatible with Nokia Suite.
   
9. If Nokia Suite is not able to find your Symbian or S40 phone, try reinstalling Nokia Suite software in your PC.
   
10. If possible, check if your phone can be successfully connected to another PC.
    

If the above actions don't help, reset the device back to factory settings.

Check also that you have the latest device software version installed in your mobile device.

You can format your device by typing *#7370# in standby mode. Before the device is reset, you may need to provide the lock code. The default lock code is 12345.

IMPORTANT NOTICE!

• Formatting the device will permanently erase all user data and settings as well as add-on applications and operator specific settings.
• If you have made a backup of the device data, the data can be restored from the backup after formatting but some add-on applications can have restrictions that they are not restored from the backup.
• If you use formatting to repair faulty behaviour of the device, restoring the backed-up data files may restore the unwanted behaviour as well. In that case, a partial restore may resolve the situation.
• The contents of the SIM card and memory card (MMC) are not erased during formatting. Note, however, that in some device models (e.g. Nokia N8-00, E7-00, E6-00, C7-00 and X7-00) the internal mass memory E: will be formatted in this situation. It is therefore important that you back up all your data from the E: mass memory before resetting the device. Use Nokia Suite to back up the contents to your PC.
  

To check the unique Wireless Local Area Network (WLAN) Media Access Control (MAC) address that identifies your Nokia phone, enter *#62209526# in the idle mode (or with touch screen phones after opening the dialler).

SMS message may get converted to MMS message in the following situations:

1) When sending a long SMS message

In some devices the message type gets converted from SMS text message to MMS multimedia message if the message length exceeds the device-specific setting which is typically 5 - 10 SMS submessages (around 760-1520 characters). If the message is longer, it is converted to MMS to avoid potential issues in handling long text messages in the recipient device. The cost of a SMS message consisting of several concatenated submessages may also be higher than the cost of a single MMS message.

The conversion from SMS text message to MMS multimedia message occurs when the automatic message type is selected in the message options. This is the default mode where the device tries to automatically select the best mode for the message.

The conversion from SMS to MMS can be avoided by selecting Options > Sending options > Message type > Text when in the Text message window writing the message. The message is then always sent as SMS text message and no conversion to MMS occurs.

The maximum number of concatenated SMS submessages can be up to 10 (around 1520 characters). In multimedia mode the message length can be longer.

2) No phone number defined in user contact information

If sending SMS to one or more recipients and one of the potential recipients has only email address and no phone number, the SMS will be converted to MMS. This is independent of the number of the potential recipients.

In order to avoid the conversion to MMS, remove from the recipient list the contacts which don't have a phone number defined.

Select Settings and from the following:

• Phone language: Change the language of the display. Note that changing the language also affects the format used for date and time and the separators used, for example, in calculations. Automatic selects the language according to your SIM card.
• Writing language: Change the input language. The characters, special characters and the predictive text dictionary are changed based on the input language.
• Predictive text: Set the predictive text input on or off. Note that the predictive text dictionary is not available for all languages.

If there is no response when tapping the touch screen, check the following:

1. Check that the device is not locked. When the device is locked, you must use the lock switch to unlock and wake up the screen.
2. If the device is not locked but only the display light time-out has expired and the display has dimmed (a situation which may occur if Keypad autolock feature has been disabled), the touch screen can be woken up by pressing any mechanical keys like menu key, volume keys, camera key or the lock key (lock key needs to be pressed twice because the first press of the key will lock the device).
3. If in a phone call, check that the proximity detector at the upper front corner of the device is not covered. The proximity sensor will lock the touch screen to avoid unintended touch screen actions during a phone call when placing the device next to your ear. Check that the proximity detector is not covered if trying to use the touch screen while a phone call is active. 
4. Remove the battery and reboot the phone.
5. If there is a memory card in the phone, try booting up without the memory card.
6. If your phone supports touch screen calibration, try to re-calibrate the touch screen (select Settings > Phone > Touch input > Touch screen calibration).
   

If the touch screen doesn't yet respond, try restoring the factory settings. If you cannot access the factory settings menu via the touch screen (Settings > Phone > Phone mgmt. > Factory settings), try entering the following reset commands via the keyboard. Before resetting the device, take a backup of your phone via Nokia Suite.

• *#7780# (try this first, it will do a soft reset).
  
• *#7370# (try this if the above command doesn't help, this command will do a hard reset).
  

If the touch screen is not yet working properly, take the phone to Nokia care point for inspection.
