Special Functions

3. Set SCR-ON in the setting mode. The [

] icon

will appear on the display.

4. Turn OFF the unit.

Alarm function is activated, the display will turn

ing.

5. To deactivate, turn ON the unit and set SCR-

OFF in the setting mode.

IMPORTANT: • To activate the function, be sure to switch OFF the power after having con-

nected the cable for the alarm. (Connecting it after the power is off may acti-

vate the alarm)

• The alarm will not be active unless the PWR switch is turned off.

• The alarm function will not operate if the power is OFF in the ACC power sup-

ply control function.

• The alarm cable A/B provided with DR-135/435 is not compatible with this unit.

How the alarm operates

When the alarm cable is removed from the port or cut without using the proper sequence, the alarm

sounds for 10 minutes. During the alarm, the unit goes to receive on memory channel 99, accord-

ing to its pre-programmed setting (TSQ/DCS accepted).

To cancel the alarm setting while the alarm is functioning

1. When a signal is received on ch.99 the alarm stops. If ch.99 is empty the unit contin-

ues monitoring the Main-VFO frequency. Turning on the unit with the SQL key

pressed also cancels the alarm.

2. When the power is turned OFF again, the alarm setting resumes.

NOTE: The alarm feature on DR-635TA version functions in a slightly different manner.

1. When the alarm starts, the unit alternates between transmit and receive on ch.99 every 5

seconds for 5 minutes.

2. Setting and operation of the function are the same as other versions.

This feature allows you to monitor and to control the alarm from a remote place by using

ch.99 in the memory mode.
