Remove the battery, then insert the charger into the handset. Check if there is a flashing battery icon shown on the display, then check if the handset is beeping and flashing ‘Low Battery’ or ‘Insert Battery’ indicators.
If neither of the above occur, the handset may be defective and should be returned to your Thuraya Service Provider.
You should also check the battery contacts for dust or corrosion. If they appear soiled, clean the contacts and try a power reset.
If the handset is displaying the flashing icons and sounding the beep alerts, re-insert the battery, ensuring it snaps into a locked position.
