BATTERY LIFE
The alkaline battery life is 1000 hours under continuous use, and
approximately the shelf life of the battery when used one hour per
day. To conserve battery life, make sure the switch is Off when
the A15TG is not being used.
The A15TG will not be harmed by dc present in microphone cir-
cuits used to power condenser microphones.
BATTERY INSTALLATION
Remove the end cap by turning counterclockwise. Insert the bat-
