Professional  Wireless  System 

9.  TROUBLE SHOOTING 

wireless system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equip­
ment needs repair. Make sure you have followed the setup procedures in section 7. Check out the equipment and 
cabling that connects the wireless to your sound system and then go through the trouble shooting guide in table A on 
pages 12 and 13. 

If this doesn’t fix the problem, then go to section 10 for SERVICE AND REPAIR.

mance.

POSSIBLE CAUSE 

1.  OFF-MUTE-ON switch in off position. Batteries low in 

R33B rechargeable version. 

2.   Power supply not plugged in or AC receptacle dead. 
3.  Power supply cable or power supply defective. 

1.   M33 not turned on. 
2.   Dead battery in M33. 
3.   M33 is on different frequency than R33. 
4.   Antenna not hooked up to R33 properly. 
5.   Optional battery in R33B not charged. 

1.  M33 Is not getting an audio signal. Defective mic, 

instrument or cable. 

1.  R33 OFF-MUTE-ON switch is in the mute position. 
2.   R33 VOLUME control is turned down completely. 
3.  Cable between R33 and sound system is defective. 
4.  Sound system input off or defective. 

1.  Gain control on M33 set much too low. See section 6 

for correct adjustment. 

1.  Hiss on signal being fed into M33. Disconnect mic or 

signal source. If hiss stops, problem is in signal 
source, not with wireless. 

2.  Hiss in sound system hooked up to R33. Turn the R33 

off. If hiss still remains, then the hiss is in the sound 
system. 

1.   See above procedure for hiss level and follow the 

same steps. 

1.   M33 gain set much too high. The red MODULATION 

LEVEL light will be on much of the time. See section 6 
for correct adjustment.
