Using a PTT Headset
You can plug an optional headset into the
right side of your PMR1290 or PMR1295
handset. By pressing the PTT button to
transmit you can then talk with other
radios.
Roger Beep
The Roger beep is a tone which is automatically transmitted
whenever the PTT button is released. This alerts the receiving party
that you have intentionally ended the transmission, and you are
now in receive mode.
Key Tone
Your radio unit emits a confirmation tone after pressing each
button.
Duplex operation via Repeaters
This feature allows the use of local repeater stations that are
designed to automatically re-transmit your broadcast over a large
area thus giving you increased range.
Repeaters stations are privately operated radio systems installed
throughout Australia.
For example, if you wish to access a repeater station in your area
which operates on channel 2 you only need to set the Duplex
access on this Channel.
So, if you are in the range of a local repeater which transmits on
channel 2, after setting your radio to allow access of the repeater
on that channel, you will select channel 2 as normal, but during
transmit operation your radio will automatically transmit to the
repeater on channel 32.
