4.1.5.1 Connection
1. Connect a USB hub to the PC. Ensure 8242, 8262, 8262Ex charger cradles are powered with PSU and
connected to USB hub. If you upgrade only one device, you can use directly the USB connection of
your PC.
2. Connect handsets (No more than 8 handsets should be connected at the same time). There are 2
options when connecting the handsets:
a. Connect the handsets directly to the USB hub.
b. Connect chargers to the USB hub and the power adapter, and place handsets in the
chargers (See Fig 1 & 2).

Click on the "Start" button to begin the upgrade process. If "Automatically
start upgrade" is checked in the preferences menu, then the upgrade begins
immediately after the image is selected. If a handset's firmware is already up
to date, then "Completed" is displayed. A new firmware image cannot be
selected until all current upgrades are finished.
