3: Operation
3-4 PRC1077-MSOP
Presetting Channel Frequencies
The PRC1077 stores up to 10 different frequencies. These frequencies remain
in memory even if the battery pack is disconnected. Channels 1 to 9 are preset
channels; however, the last frequency entered in the MAN channel is also
retained in memory.
Presetting
Channels 1 to 9
To preset memory channels 1 to 9 (refer to the figure on page 3-1):
1. Turn the Power switch to the LOW, MED, or HIGH position.
2. Turn the CHANNEL switch to the desired channel number (1 to 9).
3. Press the CHAN SET button and hold it down while setting the new
frequency (next step). This button prevents accidental preset channel
frequency changes during normal transceiver operation.
4. Turn the Tuning control (MHz) switch to either UP or DN until the two
right digits (MHz) in the LCD indicate the desired frequency.
5. Turn the Tuning control kHz switch to either UP or DN until the three left
digits (kHz) in the LCD indicate the desired frequency.
6. Release the CHAN SET button. The new preset frequency is now entered
into memory.
Presetting the
MAN Channel
To set the MAN channel:
1. Turn the POWER switch to the LOW, MED, or HIGH position.
2. Turn the CHANNEL switch to MAN.
3. Turn the MHz switch to either UP or DN until the first two digits in the
LCD (MHz) indicate the desired frequency.
4. Turn the kHz switch to either UP or DN until the last three digits in the
LCD (MHz) indicate the desired frequency.
5. The new frequency is now entered into memory.
POWER Provides connection for external power supply when the
PRC1077 is used in a vehicular radio set configuration.
When the connector cover is removed, the PRC1077 is
disconnected from the battery pack so the radio will not
operate. Rechargeable batteries can be recharged through
this connector.
