DTMF (DUAL TONE MULTI FREQUENCY) CALLS
Note: To make a DTMF call, you must have an optional microphone with a DTMF keypad. Ask your
dealer for more information.
There are two methods of making a DTMF call:
• Manual dialing
• Store and sending
To make a call by dialing manually:
1 Press and hold the PTT switch.
2 Enter the desired digits using the microphone keypad.
• The corresponding DTMF tones sound each time you press a key.
• 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 hold down
the PTT switch while pressing the keys on the keypad. The DTMF code will be
sent automatically when you press a key.
To make a call by storing and sending:
1 Enter the desired digits using the microphone keypad.
• The digits appear on the display as you enter them.
2 After entering the complete number, press the PTT switch.
• If you are using the transceiver in Conventional mode, the DTMF code is
transmitted after pressing the PTT switch.
• If you are using the transceiver in a Trunking system, the DTMF code is transmitted
after a connection is established. Releasing the PTT switch before a connection is
established will stop the transmission from occuring.
• If you are using the transceiver in a RIC (Repeater Inter-Connect) Trunking system,
the DTMF code is transmitted after a connection with the telephone system is
established.
Note:
◆ Store and send must first be activated by your dealer in order for it to function.
◆ You can only store up to 16 digits before sending. Entering more than 16 digits will cause an
error tone to sound.
◆ In store and sending mode, if you switch the power OFF before sending the number, the number
will be cleared from memory.
