Super-Minature Belt Pack Transmitters
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.
“Loc” APPEARS IN DISPLAY WHEN ANY BUTTON IS PRESSED
1) Control Panel is locked. (See Operating Instructions, Locking
and Unlocking the Control Panel.)
“Hold” APPEARS IN DISPLAY WHEN ARROW BUTTONS ARE PRESSED
1) Reminder that it is necessary to hold down the AUDIO or FREQ
button to make adjustments to the audio gain or frequency settings.
“PLL” APPEARS IN DISPLAY
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 8 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.
