FREQUENCY STEP SIZE

Choosing the correct frequency step size is essential in order to select your exact

receive frequency using the ENC control. You can select your desired frequency

step size from: 5, 6.25, 10, 12.5, 15, 20, 25, 30, 50, or 100 (kHz).

To change the frequency step size:

1 Press [STEP].

• The current frequency step size appears.

2 Rotate the ENC control to select your desired frequency step size.

3 Press any key other than [MONI], [LAMP], or [PTT] to set the selected

frequency step size.

Note: If you change to a frequency step size that does not match the current operating frequency,

the transceiver automatically adjusts the frequency to match the new frequency step size.

TONE ALERT

Tone Alert provides an audible alarm when signals are received on the frequency

you are monitoring. In addition, it shows the number of hours and minutes

elapsed after signals have been received. If you use Tone Alert with CTCSS

or DCS, it sounds only when a received CTCSS tone or DCS code matches the

tone or code you selected. Turning this function ON is convenient for when you

are not sitting in front of the transceiver, as confirmation of the receipt is possible

while away from the transceiver.

1 Select your desired frequency or memory channel.

2 Press [ ].

• The OFF/ ON setting appears on the display.

• When Tone Alert is set to ON, the “ ” icon appears on the display.
