5 OPERATING THROUGH REPEATERS

REVERSE FUNCTION

The reverse function exchanges a separate receive and transmit frequency. So, while using a repeater, you can manually check the strength of a signal that you receive directly from the other station. If the station’s signal is strong, both stations should move to a simplex frequency and free up the repeater.

TONE FREQ. ID SCAN

This function scans through all tone frequencies to identify the incoming tone frequency on a received signal. You may use the function to find which tone frequency is required by accessing your local repeater.

1While the Tone function is ON, press [F], [TONE] (1 s) to start the Tone Freq. ID scan.

When the transceiver receives the signal, the scan starts.

TX: 144.725 MHz TX: 144.725 MHz TX: 144.725 MHz TX: 145.325 MHz

RX: 145.325 MHz RX: 145.325 MHz RX: 145.325 MHz RX: 144.725 MHz

To swap the transmit and receive frequencies:

Press [REV] to switch the Reverse function ON (or OFF).

“R” appears when the function is ON.

Note: You can turn the Reverse function ON when you are operating in Simplex mode. However, it does not change the TX/ RX frequency.

AUTOMATIC SIMPLEX CHECK (ASC)

While using a repeater, the ASC function periodically checks the strength of a signal that you are receiving directly from the other station. If the station’s signal is strong enough to allow direct contact without a repeater, “” indicator on the display starts blinking.

Press [REV] (1 s) to switch the function ON.

” appears when the function is ON.

While direct contact is possible, “” blinks.

To quit the function, press [REV].

Note:

Pressing the PTT switch causes “ ” icon to quit blinking.

ASC can be activated while operating in Simplex mode. However, it does not change the TX/ RX frequencies.

ASC does not function while scanning.

Activating ASC while using Reverse switches Reverse OFF.

If you recall a memory channel or the Call channel that contains a Reverse ON status, ASC is switched OFF.

ASC causes received audio to be momentarily intermitted every 3 seconds.

ASC does not function when the band is not selected for operation.

To reverse the scan direction, turn the Tuning control or press []/ [].

To quit the function, press [PTT] or [].

When the tone frequency is identified, a beep sounds and the identified frequency appears.

2Press [] to program the identified frequency in place of the current tone frequency.

Press [] if you do not want to program the identified frequency.

Press []/ [] while the identified frequency is blinking, to resume scanning.

Note: Some repeaters do not re-transmit the access tone in the downlink signal. In this case, check the other station’s uplink signal to detect the repeater access tone.
