Parameter Setting Mode

APO-Auto Power OFF

This feature will automatically shut off the transceiver. It is useful in mobile operation to avoid

draining the car battery. If there is no activity or use of the radio, it will turn off automatically after

30 minutes followed by a beep sound.

1. Default is APO-OFF.

2. Rotate dial to select APO-ON to activate the

function.

During the ON setting

Tone-Burst Frequency

This is to access Tone-Burst repeaters which require a certain pitch of audible tone to activate

“sleeping” repeaters. Usually, a repeater system does not require the tone once the repeater is

activated.

Tone Burst frequency can be set to ALERT, 1750Hz, 2100Hz, 1000Hz and 1450Hz.

(ALERT is an intermittent recalling sound)

Clock shift

In the unlikely event that CPU clock noise is present on a particular operating frequency pro-

grammed into the radio, you can shift the CPU clock frequency to avoid the CPU clock noise,

which normally is so weak that it is inaudible even if the radio is tuned exactly to its frequency.

1. The [ALERT] icon appears on the display.

2. By rotating the main dial, the display changes

as below and Tone Burst frequency setting is

changed.

ALERT TB 1750

TB 2100

TB 1000 TB 1450

1. [CKSFT OFF] icon appears on the display.

2. By rotating the main dial, the display changes

as shown and the Clock shift setting is changed.

CKSFT OFF CKSFT ON

(Refer page 27 for how to enter the setting mode.)
