Upgrade handset firmware
When the handset registers to the base station, it will check if there is any new handset firmware.
If the handset is placed on the charger cradle and a new firmware is available then the handset will
automatically update. In case that the handset is not placed in the charger cradle then a message
will be displayed on the screen to inform you that there is a new firmware available. In order for the
handset to start the upgrading process you have to confirm by pressing the “Upgrade” soft key.
Note: To double check that your handset is using the latest firmware, go to the Main Menu

corresponds to each base station FW.
Please note, the batteries in the handset are not covered under manufactures warranty. These are
standard AAA batteries. In the unlikely event you encounter any issues with the handset holding
charge, we recommend you try alternate batteries.
