Autopatch Operations - Kenwood TH-78A Instruction Manual

Tone Function Operation
Press the TONE key. A "T" indicator appears on the display, and the transmitter sends the desired tone when you
press the PTT switch.
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.
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.
