The Upgrade Radio Firmware option allows you to upgrade and transfer code for multiple wireless devices on the same trunk. Access this utility from the Tools menu by selecting Trunk Utilities > Upgrade Radio Firmware.
After selecting the devices, the utility transfers code to the devices in series.
During the transfer process, you can use the View Log and View Status to see the progress. If the radio code in a device matches or is newer than what is available in your currently installed packages, a message appears in the Status column indicating that a transfer to device is not required.
The Force Radio Transfer check box allows you to force a radio code transfer to all selected devices.
