An example of switch positions and corresponding frequencies for the
“CC” Broadcasting frequency group is provided in the following table:
Broadcast Frequency Selection
Switch Position
Frequency
0 176.800 MHz
1 177.000 MHz
2 177.200 MHz
3 177.400 MHz
4 ( base frequency) 177.600 MHz
5 177.800 MHz
6 178.000 MHz
7 178.200 MHz
In each Traveling frequency group, four frequencies are available. The
factory pre–set base frequency #4 position. An example of switch positions
and the corresponding frequencies for the “TA” Traveling frequency group
is provided in the following table:
Traveling Frequency Selector
Switch Position
Frequency
0 or 1 169.445 MHz
2 or 3 170.245 MHz
4 ( base frequency)or 5 171.045 MHz
6 or 7 171.845 MHz
A label inside the receiver control panel door identifies the operating
frequencies and corresponding switch positions for each system.
CHANGING SYSTEM FREQUENCY
If one system encounters interference and its frequency switch is changed
to a new position, compatibility among the other SC systems can be
maintained by changing the remaining systems to the new position as follows:
1. Turn off all transmitters.
2. Open control panel door on each receiver and turn the tone key squelch
switch to the OFF position (right), using the supplied screwdriver.
3. Ensure that all squelch controls are set to the full left position.
4. Turn on each receiver.
5. Move the frequency selector switch on the receiver experiencing
interference to a new position (for instance, position #6).
6. Observe the receiver LEDs. If any of them are lit, interfering signals are
still present. Repeat Step 5 until you locate a clean frequency.
7. Move the frequency selector switches on the other receivers to the new
position.
8. Listen for interference on all systems. If any exists, repeat Step 6.
9. If no interference exists, adjust the transmitter frequency selector
switches so that they match the frequencies of the receivers.
10. Return the tone key squelch switch on all receivers to ON (full left
position).
