The speed at which the DTMF digits are sent can be changed. Two speed levels are avail-
able: Low (10 digits per second) and High (20 digits per second: default). To toggle between
Low and High speed, use the following procedure:

1. Press and hold in the [MHz(SET)] key for one second, then rotate the DIAL knob to

select “11 DT SPD.”

2. Press the [MHz(SET)] key, then rotate the DIAL knob to select the desired speed (“50”:

High speed or “100”: Low speed).

3. Press and hold in the [MHz(SET)] key for one second to save the new setting and exit to

normal operation.

You can also set a longer delay between the time your transmitter is keyed and the first
DTMF digit is sent. To set the delay time, use the following procedure:

1. Press and hold in the [MHz(SET)] key for one second, then rotate the DIAL knob to

select “09 DT DLY.”

2. Press the [MHz(SET)] key, then rotate the DIAL knob to select the desired speed (50/

250/450/750/1000 ms).

3. Press and hold in the [MHz(SET)] key for one second to save the new setting and exit to

normal operation.
