ADJUSTING RECEIVER SQUELCH CONTROL
The receiver squelch control is factory pre–set to accommodate most
operating conditions. However, the setting may need to be changed to
compensate for the effects of other equipment or RF interference. To adjust
the squelch control, proceed as follows:
1. Place the system where it will be used during a performance.
2. Turn the transmitter power switch off.
3. Turn the receiver volume control full counterclockwise and turn the
receiver power switch on.
4. Turn the receiver tone key squelch switch to OFF.
5. Observe the receiver LEDs. If the AUDIO or DIVERSITY lights are lit,
rotate the squelch control clockwise until all the LEDs turn off. Continue
turning the squelch control slightly past this point.
6. Turn the receiver tone key squelch switch On. To return to the factory
setting, rotate it back to its midpoint position.
NOTE: Turning the squelch control clockwise prevents unwanted signals
and noise from overriding the squelch circuit when the transmitter signal is
weak. However, it also effectively decreases the system operating range.
SC1 TRANSMITTER BATTERY INSTALLATION
1. Turn the transmitter off and open the battery compartment door by
sliding it down and pivoting it outward until it locks in the open position.
2. Insert a new 9V alkaline battery in the compartment. Observe proper
battery polarity.
3. Close and latch the battery compartment door.
SC2 TRANSMITTER BATTERY INSTALLATION
1. Turn the transmitter off and unscrew the battery cover.
2. Insert a new 9V alkaline battery into the contacts on the handle. Observe
proper battery polarity.
3. Reinstall the battery cover.
NOTE: A fully charged, heavy-duty, 8.4V NiCad battery can be used, but is
not recommended, due to its significantly shorter life.
