SYMPTOM 

             

 

 

 POSSIBLE CAUSE

HISS AND NOISE -- AUDIBLE DROPOUTS 

1)   Transmitter gain (audio level) far too low.

 

2)   Receiver antenna missing or obstructed.

 

3)   Transmitter antenna broken or missing.

 

4)   Operating range too great.

 

5)   Signal interference. Turn off transmitter. If receiver’s signal  

 

 

strength indicator does not drop to nearly zero, this indicates an  

 

 

interfering signal may be the problem.  

 

 

Try a different operating frequency.

1)   Control Panel is locked. (See Operating Instructions, Locking  

and Unlocking the Control Panel.)

1)   Reminder that it is necessary to hold down the AUDIO or FREQ  

 

 

button to make adjustments to the audio gain or frequency settings.

1)   Indication that the PLL is not locked. This is a serious condition  

 

 

that requires factory repair. It may be possible to operate on  

 

 

another frequency far removed from the one that was selected  

 

 

when the unlocked condition was indicated.

TRANSMITTER WON’T RESPOND TO REMOTE CONTROL
 

1.   If LCD blinks “rc oFF”, transmitter has not be configured  

 

 

to respond to the remote control. See “Remote Control Operation”  

 

 

on page 16 for instructions on how to configure.

 

2.   If LCD blinks “- - - - - -”, transmitter is already set as 

 

 

requested by the remote control.

 

3.   If transmitter doesn’t not respond at all, try moving the remote  

 

 

control closer to the microphone or increasing the remote control’s  

 

 

loudness setting, or increasing audio level on transmitter.

 

4.   SM, SMD and SMQ transmitters must have firmware ver. 1.5 

 

 

or higher to work with the RM. All “a” versions of the SM Series will 

 

 

work from firmware ver. 1.0 and up. The firmware version will flash 

 

 

briefly on the right side of the LCD during power up.

RM Troubleshooting

SM FREQUENCY CHANGES, BUT NOT TO DESIRED FREQUENCY 
 

1)   RM set on different block than transmitter in question. RM uses  

 

 

hex code to set frequency - set RM to proper frequency block, or  

 

 

use hex code method to change frequency.

RM FAILS TO CHANGE SETTINGS ON TRANSMITTER 
 

1)   Make sure volume of RM and proximity of microphone are 

 

 

sufficient to engage transmitter.

 

2)  Make sure transmitter is not in Sleep mode.
