Operation Manual

3-22 Operations
The VOL UP/DOWN keys adjust the sound volume for both Fog Alert and
listening modes. When the radio power supply is switched on, the sound
volume is same as was last used. Each handset has its own volume settings.
To cancel the Fog Alert operation, again press FUNC followed by #/FOG
or press the CLR key.
3.5.19 DTMF Interface Operation (Optional)
A cellular fixed wireless terminal (such as the RAYCOM Fixed Cellular
Wireless Terminal) or other radio communications device with DTMF
interface (such as some Inmarsat Mini-M’s) can be connected to the
RAY230 or RAY230E, using an optional interface to the AUX terminal. One
handset is used for DTMF (cellular) phone operation while optional
handsets will monitor transmissions on the last selected working or weather
channel. When any DSC call is received or a distress call is transmitted,
phone operation is interrupted and radio operation is given priority. Channel
70 is always monitored for incoming DSC calls.

keypad. The number you just input appears on the dot matrix display. If

digits are visible.
