The transmitter is powered by a standard alkaline,
lithium or LiPolymer rechargeable 9 Volt battery. Alka-
line batteries will provide about 3.5 hours of operation,
a lithium battery about 6.5 hours, and a LiPolymer bat-
tery about 4 hours per charge.
Note: The battery status lamp will function
normally only with alkaline or lithium batteries.
Standard zinc-carbon batteries marked “heavy
duty” or “long-lasting” are not adequate, since they
will only provide about 30 minutes of operation.
LiPolymer rechargeable batteries work fine, but they run
down quite abruptly, so the LED on the transmitter will
not give you adequate warning before the battery stops
working. There are, however, a number of Lectroson-
ics receivers that incorporate a Battery Timer function
which tracks the amount of time the transmitter signal is
detected. Refer to your receiver manual to determine if
this function is available, and for instructions on mea-
suring the battery life and using the timer. After measur-
ing the battery life in advance, the timer will display the
operating time and give you plenty of warning.
The battery compartment is located in the lower sec-
tion of the transmitter, between the two printed circuit
boards. Follow the steps illustrated to install a fresh
battery.
Battery Installation
Note the two differently sized holes in the battery
contact pad inside the Battery Compartment. Insert
the battery so that the large hole in the battery contact
pad will line up with the large contact on the battery. A
spring-loaded plunger in the bottom of the compartment
(opposite the contact pad) secures the battery in place.
The battery status is indicated by the Power LED on the
bottom panel. The Power LED glows green when a new
battery is installed, then changes to red as battery con-
dition deteriorates. It begins blinking red as the battery
nears depletion. Battery status is also displayed on the
front panel LCD of some Lectrosonics receivers. See
the associated receiver manual for further details.
If the power switch has been configured to function as
an audio mute switch, the LED will double blink green
slowly when the switch is turned off, and the power will
remain turned on.
Note: It is possible to insert the battery backwards
and still be able to close the battery door. No
damage will occur but the transmitter will not
operate in this condition.
