About Batteries
The transmitter is powered by two AA batteries.
Lithium batteries are recommended for longest life.
At 50 mW, the runtime is typically over 14 hours with
lithium batteries.
Rechargeable NiMH batteries can also be used, but
the capacity diminishes over time with each suc-
cessive recharging cycle. Test the batteries by fully
charging them and then running them down in the
transmitter to determine the available running time.
Most Lectrosonics receivers have a timer function
that will automatically stop when the transmitter
shuts down at the end of battery life, so you will be
able to accurately see the time available.
Alkaline batteries can also be used, but the runtime
is shorter at the full output power. The available
runtime also varies significantly with different brands
of AA alkaline batteries.
Note: Standard zinc-carbon batteries marked
“heavy-duty”
or
“long-lasting”
are not
adequate.
The PWR LED glows green when the battery is
good. The color changes to red at a mid-point of
operating life, and will continue to glow red until the
battery gets close to the end of its life. When the
LED begins to blink red, there are only a few minutes
remaining.
The exact point at which the LED turns red will vary
with battery brand and condition, temperature and
current drain. The LED is simply a reminder intended
to catch your attention, not an exact indicator of
remaining time.

Battery Compartments
The battery compartments are a rugged, straight-
forward design with a recessed entry that captures
the O-ring on the cap. The spring contact on the cap
maintains solid contact on the battery regardless of
its exact length.
The O-rings should be kept clean and dry, and coat-
ed with petroleum jelly on a regular basis. See page
11 for more information on preventing corrosion.
Attaching and Removing
the Microphone
The threaded WP watertight plug on the microphone
cable fits into a recessed jack on the top panel.
The recess in the opening retains the O-ring when
the plug is tightened. The Lectrosonics M152WP
lavaliere microphone is supplied with the WP plug
already installed. Other microphones can also be
terminated with this plug by following the instructions
included with the WP connector kits.
