Control Head Key Functions
The control head is normally fitted to the radio’s front panel, but can be removed and fitted in any
convenient location up to 10 metres from the radio.
Fig 3-2 on page 3-3 shows the control head that is fitted with a high visibility electroluminescent display,
tactile soft keys and a numeric keypad. A complete operator audio interface incorporating loudspeaker,
headset and microphone facilities is included.
Key operation is shown in Fig 3-3, Fig 3-4 and Fig 3-5. Note that Key 1 to Key 13 are soft keys (that is,
the function changes depending on the action being performed) that allow selection of the displayed
function.
The display turns off if no key has been pressed for 10 minutes. Any key press This facility is enabled or
disabled within the Radio Config settings (see page 22).
Hearing loss can result when listening to audio at excessively high levels, or for prolonged
periods of time. Always set the volume control to a safe (low) level before using
headphones.
The legends Key 1 to Key 13 shown on the illustrations throughout this documentation
are not engraved on the keys. The legends are used in the documentation in order to
make identification easier.
