Super-Minature Belt Pack Transmitter

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 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

interferring signal may be the problem.

Try a different operating frequency.

EXCESSIVE FEEDBACK 1) Transmitter gain (audio level) too high. Check gain adjustment

and/or reduce receiver output level.

2) Talent standing too close to speaker system.

3) Mic is too far from user’s mouth.

“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 while adjusting 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 9 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.

4. Be sure the transmitter has ﬁrmware v1.5 or newer

(see section on Power On Boot Sequence).
