SPLIT TONE OPERATION

The VX-177can be operated in a Split Tone configuration via the Set mode.

2. Rotate the DIAL knob to select Set Mode Item 43: SPLIT.

3. Press the [F] key momentarily to enable adjustment of this Set Mode Item.

When the Split Tone feature is activated, you can see the following additional parameters following the “DCS” parameter (while selecting the tone mode by pressing [F] ￿ [1(SQ TYP)]):

TONE CALLING (1750 HZ)

If the repeaters in your country require a 1750-Hz burst tone for access (typically in Eu- rope), you can set the MONI key to serve as a “Tone Call” switch instead. To change the configuration of this switch, we again use the Set Mode to help us.

1. Press the [F] key, then press the [0(SET)] key to enter the Set mode.

2. Rotate the DIAL knob to select Set Mode Item 27: M/T-CL.

3. Press the [F] key momentarily to enable adjustment of this Set Mode Item.

4. Rotate the DIAL knob to select T-CALL on the display.

5.Press the PTT switch to save the new setting and exit to normal operation.

To access a repeater, press and hold in the MONI key for the amount of time specified by the repeater owner/operator. The transmitter will automatically be activated, and a 1750- Hz audio tone will be superimposed on the carrier. Once access to the repeater has been gained, you may release the MONI key, and use the PTT switch for activating the transmit- ter thereafter.
