See p. 11.

2) Receiver on wrong frequency or wrong block.

3) Receiver connected incorrectly to sound system.

4) Transmitter in standby mode.

RECEIVER RF INDICATOR OFF 1) HH not turned on.

2) HH is in “standby” (non-transmitting) mode. Check the LCD for the

antenna/transmission icon status.

3) Batteries are dead or installed backwards.

4) Receiver antenna missing, defective or improperly positioned.

5) HH and receiver not on same frequency block.

Check labels on HH and receiver to be sure they are operating

on the same frequency block.

agreement.

7) Operating range is too great.

8) Receiver antenna missing, incorrect frequency or disconnected.

NO SOUND BUT RECEIVER AUDIO LEVEL METER INDICATES SOUND

1) Receiver audio is muted. (Unmute receiver.)

2) Receiver audio output levels set too low.

3) Receiver audio output is disconnected or cable defective

or miswired.

4) Sound system or recorder input level is turned down.

DISTORTED SOUND 1) HH Audio Gain set too high. Speak or sing into the HH and check

the Audio Level LEDs, Audio Level bar graph in the HH LCD and

corresponding indicators on the receiver.

2) Receiver output level may be too high for the sound system or

recorder input.

3) Excessive wind noise or “breath pops.” Microphone may require

an additional wind screen.

4) HH Frequency setting is not correct (when used with

non-Digital Hybrid receiver).

5) Compatibility Mode mismatch between transmitter and receiver.

6) Mic capsule damaged or defective

HISS AND NOISE -- AUDIBLE DROPOUTS 1) HH Audio Gain set too low. See page 10 for proper audio gain

setting.

2) Receiver antenna missing, defective or obstructed.

3) Operating range too great.

4) Interference may be present. Turn transmitter off and observe the

RF level indicator on the receiver. Change frequency if necessary.

5) Return attenuator control back to default setting of “F”, then

readjust audio gain per instructions on page 10

EXCESSIVE FEEDBACK 1) HH Audio Gain set too high. Check level adjustment,

reduce receiver output level, or both.

2) Microphone too close to speaker system.
