To see your current version on your IsatPhone Pro, go to Menu > Settings > About > Firmware version. 

Please follow the steps below in sequence.

STEP ONE – USB Drivers

Please note, you will need to install the USB drivers first before connecting the handset to your PC.

If you do not do this, Windows will try to use another driver that is not compatible and therefore, it will not work.

Driver installation is a 3 step process

• Download drivers
• Unzip drivers
• Install drivers

All three steps are detailed in the instruction guide.

USB Drivers are compatible with Windows XP, Windows Vista, Windows 7, 8 and 10.
(For Windows 7, USB 3.0 is not supported.)
