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.
