18. Troubleshooting

The tablet does not switch on

Remove/reinstall the battery. Then charge the tablet until the battery icon stops 

scrolling. Unplug the charger and try to switch the tablet on.

The display shows BLOCKED when you switch on the tablet

Somebody tried to use your tablet but didn’t know the PIN code nor the unblocking code (PUK). 

Contact your service provider.

The display shows IMSI failure

This problem is related to your subscription. Contact your operator.

The network symbol is not displayed

The network connection is lost. Either you are in a radio shadow (in a tunnel or between tall 

buildings) or you are outside the network coverage area. Try from another place, try to reconnect 

to the network (especially when abroad), or contact your network operator for assistance/

information.

The touch screen responds slowly or improperly

If your device has a touch screen and the touch screen is not responding properly, try the

following:

-

 Remove any protective covers from the touch screen. Protective covers may prevent the 

device from recognising your inputs and are not recommended for touch screen devices.

-

Ensure that your hands are clean and dry when tapping the touch screen.

-

Restart your device to clear any temporary software bugs.

-

Ensure that your device software is upgraded to the latest version.

-

If the touch screen is scratched or damaged, take it to your local dealer.

Your battery seems to over heat

You might be using a charger that was not intended for use with your tablet. Make sure you always 

use the authentic accessory shipped with your tablet.

Your tablet doesn’t display the phone numbers of incoming calls

This feature is network and subscription dependent. If the network doesn’t send the caller’s 

number, the phone will display Call 1 or Withheld instead. Contact your operator for detailed 

information on this subject.

You can’t send text messages

Some networks don’t allow message exchanges with other networks. First check that you have 

entered the number of your SMS centre, or contact your operator for detailed information on this 

subject.

You can’t receive and/or store JPEG pictures

A picture may not be accepted by your tablet if it is too large, if its name is too long, or if it doesn’t 

have the correct file format.

You feel that you have missed some calls

Check your call divert options.
