How to install the batteries in your M3R Stereo Receiver
System Operation
Placement:
Location
For best operation, place the M3T Stereo Transmitter near the performance
location. The transmitter should be at least 1 meter (3 feet) from the
receiver. Keep antennas away from noise sources such as digital
equipment, motors, automobiles and neon lights, as well as away from
large metal objects. Audio-Technica recommends that you do not locate
the M3T Stereo Transmitter in the same rack with a wireless microphone
receiver.
System set-up:
1. Plug in the included AC adapter and connect to transmitter's DC
input.
2. Insert two AA batteries in the receiver, observing polarity as indicated.
3. Power on your receiver (without earphones) with volume in
minimum position. Note: At this point, check to be certain the
RF indictor is not illuminated. If it is illuminated before you
have powered on the transmitter, this means the frequency
you have chosen is already in use. Choose another frequency.
4. Power on the transmitter.
5. Set the receiver and transmitter to the same frequency group and
frequency channel. ( See page 17. ) Note: Do not set more than
one transmitter to the same frequency.
6. Check the RF LED on your receiver to be certain it is illuminated.
(This indicates that it is receiving a signal from the transmitter.)
7. Power off both units (transmitter and receiver).

Each M3R Stereo Receiver uses two 1.5V AA batteries, not included.
Alkaline type is recommended. Always replace all batteries. Make
certain the receiver power is Off before replacing batteries.
1. Open the battery compartment door by sliding tabs in the direction
of the arrows and rotating the door open.
2. Observe correct polarity as marked and carefully insert two fresh
1.5V AA alkaline batteries
3. Close the door, making certain the latches click securely in place.
Note: The M3R Stereo Receiver's "fuel gauge" battery indicator
displays a maximum of four bar segments. When it flashes
" LOW.BAT ", the batteries should be replaced immediately to
ensure continued operation.
Audio set-up:
8. Connect audio source(s) to inputs on the rear panel of the
transmitter. There are two combination audio inputs on the back
panel; each offers both XLR and
cable for the connection between the transmitter and the audio
source (mixer or instrument). Note: If you want to send the
audio signal through your transmitter (to another transmitter
or recording device, for instance), use the Loop output connectors
on the back of the M3T Stereo Transmitter. The R/2 XLR jack
duplicates the unprocessed signal of the R/2 input; the L/1 XLR
jack duplicates the unprocessed signal of the L/1 input. These
are not affected by front panel settings.
9. Turn on the transmitter.
10. Set the attenuator on rear panel of transmitter to appropriate level.
If AF level indicators (on right side of transmitter LCD) are consistently
at or above +3, set the attenuator to -10 or -20 dB or turn the trim
down for corresponding audio input.
11. Trim levels are set at the factory to the maximum position; adjust if
necessary. ( See page 12. )
12. Plug earphones into jack on receiver. Turn the locking ring
clockwise until tight. NOTE: Do not put the earphones in your
ears at this point.
13. Turn on receiver with volume in minimum position.
14. With volume on receiver at minimum position, put earphones into
your ears and gradually increase volume until appropriate level is
reached.
