Note:
If the transmit frequency is outside the allowable transmit frequency range when using
Reverse, pressing [PTT] will cause an error tone to sound and transmitting will be inhibited.
If the receiving frequency is outside the receiving frequency range when using Reverse,
an error tone will sound and Reverse will not operate.
The ARO (Automatic Repeater Offset) will not function when Reverse is ON.
You cannot switch Reverse ON or OFF while transmitting.
TRANSMITTING A 1750 Hz TONE
Most repeaters in Europe require that a transceiver transmit a 1750 Hz tone. On
the E type model, simply pressing [PF] causes it to transmit a 1750 Hz tone. It is
also possible to program [1750] on the front panel as a [PF] key for transmitting a
1750 Hz tone.
Note: The transceiver continuously transmits a 1750 Hz tone until you release the [PF] key
(1750).
Some repeaters in Europe must receive continuous signals for a certain period of
time, following a 1750 Hz tone. This transceiver is also capable of remaining in
the transmit mode for 2 seconds after transmitting a 1750 Hz tone.
1 Enter Menu mode and access Menu No. 33 (1750.HD), then press [F].
2 Rotate the ENC control to select “ON”, then press [F] to store the setting.
3 Press [MENU] or [PTT] to exit Menu mode.
Note: While remaining in the transmit mode, the transceiver does not continuously transmit a
1750 Hz tone.
