Please be advised that a fault has been identified with IsatPhone Pro firmware versions 5.1.0 and 5.2.0 (the latest) that affects handsets manufactured since 7 September 2012.
The fault causes the battery on these phones not to charge while the handset 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.
Our engineers are producing a new version of the firmware which will resolve this problem. We currently expect this will be fully tested and available for release by 8 February 2013.
Only a small number of IsatPhone Pro units are affected by the fault. They are those handsets shipped since 7 September 2012 with IMEI numbers above 353032041133824 (operating with firmware versions 5.1.0 or 5.2.0).
Handsets manufactured before 7 September 2012 will recharge as normal, switched on or off, with all firmware versions, including 5.1.0 or 5.2.0. No action is required for users of these handsets.
You can check a handset’s IMEI number in three ways:
- Printed on the label on the original presentation box
- Printed on the label inside the battery compartment
- Through the phone menu (under Settings > About).
Users with an affected handset are advised to follow these simple guidelines:
- Keep the phone switched on during charging
- Maintain a full to half-charge until their IsatPhone Pro has been upgraded with the new firmware.
All IsatPhone Pro users are requested to upgrade to the new version of firmware when it becomes available on 8 February 2013. Version 5.2.0 has been withdrawn in the meantime.
Orders for new IsatPhone Pro handsets received on or after Friday 25 January 2012 will not be shipped until the new version of firmware has been released.
Inmarsat apologises to customers for any inconvenience. We will send a further communication to advise on upgrading once the new firmware is available.
Please contact your sales representative if you have any further questions.
