Auto Power Off
To maximize the life of the battery, power automatically shuts off after 10 minutes of non-use.
Low Battery Indicator
Battery indicator status shows full, half or recharging. If the battery power is empty, power is
turned off immediately.
IMPORTANT!
Use the Cooper/Cedar AC adapter/charger exclusively and plug into the
correct AC output. It takes 5 hours to fully recharge for 12 hours of continuous use. When fully charged, the
charge light goes off.
System Reset
When battery power is completely depleted, the tester may not work even though it has been recharged. In this
case, press the System Reset Button.
OUTPUT
USB Virtual COM Port
When the tester is connected to a computer’s USB port and
turned on, Windows XP or Vista will recognize the tester and ask
to connect to the Internet. Allow Windows Update to connect
and follow the instructions on your screen to download and
install two drivers for the USB Virtual Com Port. For Windows
98, ME and MAC, go to www.ftdchip.com/Drivers/VCP.htm.
The PC and tester will communicate through the USB port the same as a
com port. To verify the COM port number, open the Device Manager.
