HEADSET/LAVALIER COMBO AND 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 BATT indicator should flash once briefly as you turn on the mic indicating that the
mic has sufficient power. If the BATT stays on, it indicates that the battery has insufficient power and should be changed.
If the BATT does not light at all and the mic does not work, it indicates the the battery is dead and you should 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.
Do not switch the mic on and off rapidly, because you wont get a true indicationfrom the BATT indicator.
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/Headset combo wire is the transmit antenna. Do not roll up, coil or shorten during use. This wire must be kept as
straight as possible.
