7 Autopatch Operations

(U.S.A. versions only)

Some repeaters offer a service called autopatch. This feature allows you to dial a telephone number from your transceiver and carry on a telephone conversation.

This function requires the use of a DTMF (Dual Tone Multi Frequency) keypad. The transceiver also provides four additional keys - A, B, C, and D - in addition to the normal 12 keys found on your telephone.

These keys are required for various control operations by some repeater systems. A chart listing the various tone frequencies generated by the keypad is provided below.

To activate the keypad:

Press and hold the PTT switch

Dial the number just as you would on a normal telephone by pressing the appropriate keys.

Note

Some repeaters require a special key sequence to activate the autopatch function. Check with the control operator for this sequence.

You will hear and transmit a single tone if you press the VFO key before pressing one of the numeric keys (see the chart at right).

Selecting Delay Time

(Direct keyboard entry only)

It’s easier to enter a long string of numbers if you don’t have to hold down the PTT switch while you enter them. To instruct the transceiver to remain keyed for 2 seconds after pressing each number:

1 Turn the power off.

2 Press and hold the 2 key and turn on the power.

3 Release the 2 key.

You are now able to enter numbers without pressing and holding the PTT switch.

Repeat 1 and 3 to cancel the delay time.
