Troubleshooting
SYMPTOM
POSSIBLE CAUSE
HH/E01 WILL NOT POWER ON
1) Batteries are inserted backwards.
2) Batteries are dead, or too low to be used.
HH/E01 MODULATION LEDs OFF
1) Audio Gain set too low.
2) Battery is inserted backwards. Check LCD for power indication.
3) Mic capsule is damaged or malfunctioning. Contact the factory
for repair.
HH/E01 MODULATION LEDs GOOD BUT NO SOUND
1) Talkback function is engaged (release multi-function button).
See p. 10
2) Receiver on wrong frequency or wrong block.
3) Receiver connected incorrectly to sound system.
RECEIVER RF INDICATOR OFF
1) HH/E01 not turned on.
2) HH/E01 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/E01 and receiver not on same frequency block. Check labels
on HH/E01 and receiver to be sure they are operating on the
same frequency block.
6) Make sure the transmitter and receiver associated frequency
settings are in agreement.
7) Operating range is too great.
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/E01 Audio Gain set too high. Speak or sing into the HH/E01
and check the Audio Level LEDs, Audio Level bar graph in the
HH/E01 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/E01 Frequency setting is not correct.
5) Compatibility Mode mismatch between transmitter and receiver.
HISS AND NOISE -- AUDIBLE DROPOUTS 1) HH/E01 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) HH/E01 transmitting frequency set incorrectly.
5) Interference may be present. Turn transmitter off and observe the
RF level indicator on the receiver. Change frequency if necessary.
EXCESSIVE FEEDBACK
1) HH/E01 Audio Gain set too high. Check level adjustment,
reduce receiver output level, or both.
2) Microphone too close to speaker system.
3) Move microphone closer to the user’s mouth and lower the
sound system volume.
