DTMF (DUAL TONE MULTI FREQUENCY) CALLS
■ Making a DTMF Call (Keypad Models Only)
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 front panel
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 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.
