LAVALIER BELT PACK TRANSMITTER OPERATION
1. Open the battery door by sliding towards the arrow. Insert a 9V battery into the battery holder according to the
polarity indication marked on the battery housing. Close the battery door.
2. Push the power switch to the ON position. The LOW BATT indicator should flash once as the switch passes
MUTE indicating that the transmitter has sufficient power. If the LOW BATT stays on, it indicates that the
battery has insufficient power and should be changed. If the LOW BATT does not light at all, it indicates that
the battery is either dead or not positioned correctly, and you should correct the positioning or change the
battery. If the microphone is not going to be used for any length of time, push the power switch to OFF and
remove the battery.
3. The lavalier mic clip should be placed as high as possible in a vertical line with your mouth.
4. To adjust the gain (input sensitivity), remove the battery door and place the small plastic tool (included with
the unit) in the hole marked mic adj and slowly turn the tool and speak into the mic until the volume is
adjusted. Use of any other tool to adjust the gain will void the warranty.
5. The lavalier wire is the transmit antenna. Do not roll up, coil or shorten during use. This wire must be kept as
straight as possible.
