INSTRUCTIONS

A385 Battery Status

Green lamp, high, indicates battery is charged. Yellow lamp, low, indicates
battery stack should be charged. Red lamp, depleted, indicates battery is
discharged. An audible tone will sound at 10 second intervals. Permanent dam­age to the battery stack can result if battery cells are depleted without being
promptly recharged.

Charging the batteries

Model A382 is designed to recharge the battery stack of the A385 rapidly and
safely. The charger cable plugs into the charging receptacle on the rear panel
of the A385 isolator. Connect the charger’s power cord to the power line. The
POWER switch on A385 must be OFF to enable charger operation. Three red
lamps on the charger panel (one lamp for each pair of batteries in the isolator)
will light during an initial rapid charge phase. As the batteries accept charge, the
red lamps will extinguish and the charger then continues to charge at a lower
current. The A385 battery stack will usually recharge in a few hours from a com­pletely discharged state.

Disconnect the battery charging cable from the A385 while the instrument is in
use. This avoids the possibility that power line noise will be introduced via the
charger cable.

To preserve battery life, turn power switch o when instrument is not in use. Do

not allow batteries to remain in a depleted state without recharge.
