**The tester is powered by a 9-volt battery. Most
SAMs are designed to operate down to a minimum
of 7.25 volts. If the tester battery drops below that
level, incorrect test readings will result. The tester
battery should be checked periodically by
connecting a DC voltmeter between the red and
green lead wires, with the tester connected to a
SAM. Press and hold the test button for a full test
cycle (''F'' or "P'' appears and then display shuts
off), while monitoring the voltage reading on the
voltmeter. If the voltage drops below 7.5 at any time
during the cycle, the 9-volt tester battery must be
replaced. Use an extended life (alkaline) battery.
To replace the battery, remove the outer set of screws
on the faceplate and carefully lift the panel from the
body. Unplug the connector and pull battery (with
mounting tape) off the back of the tester. Attach the
connector to the new battery and mount the battery
to the case with double-backed tape. Reinstall the
faceplate and secure with the four screws.
