Low Volume

•Check volume level on Receiver and adjust as necessary.

•If volume is too low, check the “MT” adjustment inside the battery compartment of the belt-pack Transmitter. Clockwise adjustment of the “MT pot” will increase volume.

Sound Fades In and Out (Drop Out)

•Confirm Amplifier antenna is securely attached and visible from all areas of the room where the Transmitter is operating.

•Test transmitter with fully charged batteries. You can use any known, good quality batteries for testing.

No Sound From Speaker

•Confirm the Transmitter and Receiver have matching frequencies. Check both MIC 1 VOLUME and MIC 2 VOLUME. If system is equipped with optional Mic 2 Receiver, look for second antenna on back of Receiver/Amplifier.

•Confirm the plug on the microphone cable is securely fitted into the Transmitter microphone jack.

•Confirm Amplifier power supply is the correct type, is connected securely in the wall outlet and into the back of the Receiver/Amplifier.

•Turn on Receiver/Amplifier; confirm that the POWER light located on the front panel is on.

•Check volume.

•Turn on Transmitter and confirm amber RF light, located on the front panel of the Receiver/Amplifier, flashes when speaking into the microphone.

•Confirm batteries in the Transmitter are good. The red battery indicator light should flash once as you turn on the Transmitter. The same holds true with the hand-held micro- phone. If the red light stays on, your batteries are low.
