Frequency-Agile UHF Belt-Pack Transmitter

Rio Rancho, NM

Battery Installation

The transmitter is powered by a standard 9 volt battery.

We recommend using alkaline, lithium, or rechargeable

LiPolymer batteries for longest life. Standard zinc-car-

bon batteries marked “heavy-duty” or “long-lasting”

are not adequate. Alkaline batteries provide over six

hours of operation at room temperature. LiPolymer bat-

teries will last about 7 hours per charge, and Lithium

batteries can provide up to 13 hours. The battery status

circuitry is designed for the voltage drop over the life of

alkaline batteries. Because rechargeable LiPolymer bat-

teries run down quite abruptly, using the Power LED to

verify battery status is not reliable with LiPolymer batter-

ies. However, it may be possible to track battery status

using the Battery Timer function available in a number

of Lectrosonics receivers. (Refer to the associated

receiver manual to determine if this function is available

in your situation.)

Warning: Care should be taken not to leave

a fully discharged lithium battery in the

transmitter, as swelling of the battery can make

it difﬁcult to remove from the compartment.

To replace the battery, push up on the Battery Com-

partment Door and rotate it clockwise. (See photo.)

Remove the old battery and take note of the polarity

marked inside showing the location of the positive (+)

and negative ( -) terminals. (You can see the large and

small contact holes inside the battery compartment with

the door open.)

Insert the new battery correctly and rotate the door to

snap ﬂush against the housing. If the battery is inserted

incorrectly, the door will not fully close. Do not force the

door closed.
