Inmarsat IsatPhone Pro firmware version 5.1.0 and 5.2.0 charging issues identified

Global Telesat Communications have been contacted by Inmarsat with regard to the latest firmware version supplied for the IsatPhone Pro.

Firmware version 5.1.0 and 5.2.0

In recent days, a problem has been identified with units manufactured since 07 September 2012 running either firmware version 5.1.0, or 5.2.0 (the latest). Inmarsat has discovered that these two versions of firmware contain an error causing the battery not to charge whilst the phone is switched off. If the battery is allowed to run flat, then it becomes impossible to charge the phone unless a new, pre-charged battery is fitted.

Inmarsat engineers are producing a new version of firmware which will resolve this problem. We anticipate that this will be fully tested and available for release by 8th February 2013.

Up until this date, it is recommended that you do not allow the phone to go below a half charge before charging. Please make sure you switch your phone on before charging, or it will not charge.

If you are unsure of what firmware version you are running you can find out by going to Menu > Settings > About > Firmware version on your handset.
