DTMF Calls
DTMF (dual tone multiple frequency) is the tone-based
system used in the world’s telephone networks. If your
system has access to the public switched telephone
network or other networks that make use of DTMF
tones, your radio can make a call to a telephone or send
control codes to a remote device.
Your Orca 5011 radio is able to make preset DTMF calls
only.
Preset DTMF Calls
A preset DTMF call can be assigned to one of the
function keys.
To send the call:
1
Select the channel the DTMF call is assigned to.
2
Press the assigned function key.
Different preset calls may be available on different
channels.
One-Touch Preset Calls
A single one-touch DTMF call may also be assigned to
one of the function keys. It is not necessary to change
channels to send this call – simply press the assigned
function key.
When the called party responds, proceed with your
conversation.
