Battery Replacement

The WD Quick Tester uses a 3V coin-sized lithium battery to power
the SRAM during times of inactivity. The battery life is between 1.5
to 2.0 years. It will function without a battery but the data and time
will not be accurate and any test data stored in the internal database
will be lost when power is removed. Follow the steps below to replace
the battery.

proper static electricity handling procedures before attempting this
procedure.
