Operating Instructions
1. Insert Earphone or Neck Loop 3.5mm plug into the receiver’s headphone output jack
(7).
2. A green LED (6) indicates once the plug has been connected properly and the unit is
switched ON.
3. Place the receiver around the neck at chest height (pendant style) by using the lanyard
(2), or attach it to a pocket using the clip on the back of the unit (9), with the front
facing away from the body.
Note:
Keep the receiver in the line of sight of the transmitter/emitter and do not
place it in a pocket, as this will interrupt the reception and the receiver will not work
properly.
4. Select a channel by sliding the Channel selection switch (1). Choose between 2.3MHz
or 2.8MHz for Mono operation or “S” for dual-channel, 2.3/2.8MHz Stereo operation.
For most applications and especially when using the Neck Loop, Stereo mode setting
is recommended. Make sure that receiver and transmitter are set to the same channel
frequency.
5. Adjust the volume to a comfortable listening level by rotating the Volume wheel (8).
6. Disconnect the earphones/neck loop when not in use to avoid unnecessary drain on
the battery and prolong the battery life.
