Using DTMF mode
To use DTMF mode while the radio is operating on a trunking
network:
1 Set up a call to the device you want to send control codes to,
which is usually a PABX extension or PSTN number.
2 Once the call is connected, activate DTMF mode, using either a
function key or the User Settings menu.
3 Dial the control codes required.
4 Press to exit DTMF mode.
5 When you are finished with your call, press to end the call,
or change to another position on the channel selector.
Example: Accessing telebanking
In this example, the code the trunking system requires for making
a PSTN call is 0 and the telephone banking system’s phone
number is 5487777.
To access telebanking:
1 Dial 05487777 (the code plus the PSTN number) and press
the PTT key, or to make the call.
2 When the trunking system has set up the call (the display reads
GO), and the telebanking system has answered, activate DTMF
mode using either a function key or the User Settings menu.
3 Start entering the control codes required by the telebanking
system.
For example, if your telebanking system requires you to enter your
user code (e.g. 12345678), followed by , you would dial
12345678 and wait for the telebanking system’s response.
When you are finished entering control codes, exit DTMF mode,
using either a function key or the User Settings menu.
