Lectrosonics HH - Manual (Page 13)

Hand Held Transmitter
Rio Rancho, NM 13
Troubleshooting
SYMPTOM POSSIBLE CAUSE
HH WILL NOT POWER ON 1) Batteries are inserted backwards.
2) Batteries are dead, or too low to be used.
HH 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 MODULATION LEDs GOOD BUT NO SOUND
1) Talkback function is engaged (release multi-function button).
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.
6) Make sure the transmitter and receiver frequency settings are in
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.
3) Move microphone closer to the user’s mouth and lower the
sound system volume.
