Instructions for End Users
The following are step-by-step instructions for determining if your 9505A handset is in need of a software or hardware upgrade. (If you will be unable to return your phone for an exchange soon because you are in the field, at sea or in a remote location, please see Special Instructions for Users in the Field.
Step 1
Remove the door to your 9505A battery compartment. Remove the battery. Look for the barcode label.
Step 2
On the barcode label, if the letter series begins with “SUG” and has the following part number:
SUG0088MH - Your unit needs to be replaced. Please contact your Service Provider for instructions on how to have your phone replaced.
SUG0088MH1 – Iridium has already upgraded your phone and no further action is required.
SUG0088ML – Your unit may require a software reflash. To
check whether or not your phone needs the new software, enter *#91# on the keypad. The phone display should read IS05003, which means Iridium has already reflashed your phone. If your phone does not display this software code, please contact your Service Provider for instructions on how to upgrade the software in your phone.
SUG0088MM – Iridium has already upgraded your phone and no further action is required.
SUG0088MH1R – Iridium has already upgraded your phone and no further action is required.
Step 3
If your phone needs the software or hardware upgrade or both, please contact your Iridium Service Provider.
Iridium is giving its Service Providers complete instructions on replacing and reflashing phones.
Please accept our apologies for this inconvenience. Thank you.
