DTMF (DUAL TONE MULTI FREQUENCY) CALLS
MANUAL DIALING
Note: To make a DTMF call using manual dialing, you must use an optional microphone with a
DTMF keypad.
■ METHOD 1
Press and hold the PTT switch, then enter the desired digits using the
optional keypad.
• If you release the PTT switch, transmit mode will end even if the complete number
has not been sent.
• If your dealer has activated the Keypad Auto PTT function, you need not press the
PTT switch while pressing the keys on the keypad in Conventional systems. The
DTMF code will be sent automatically when you press a key.
Note: Keypad Auto PTT does not function in Trunking systems.
■ METHOD 2
Enter the desired digits using the optional keypad (maximum of 30 digits).
After entering the complete number, press the PTT switch.
• In Conventional systems, the DTMF code is transmitted after pressing the PTT
switch.
• In Trunking systems, the DTMF code is transmitted after a connection is
established. Releasing the PTT switch before a connection is established will stop
the transmission from occurring.
• In RIC (Repeater Inter-Connect) Trunking systems, the DTMF code is transmitted
after a connection with the telephone system is established. Press the key
programmed as Autodial (instead of the PTT switch) to automatically connect to
the repeater and transmit the DTMF code.
Note: If you switch the power OFF before sending the number, the number will be cleared from
memory.
