Raymarine Ray215 - Manual (Page 35)

3-12 Operation with a Fist Microphone
3.3.14 Monitor Mode
The RAY215 is equipped with 2 types of monitor operations: Dual Watch
and Tri-Watch.
Dual Watch Mode
Dual Watch monitors the selected working channel and the programmed
Priority Channel. To initiate Dual Watch, first select the working channel
to be monitored, then press the MON/1/25 key once. The selected working
channel and the Priority channel (16 or 9) are monitored for traffic.
If a signal is received on the working or Priority channel, the radio monitors
that channel as long as a signal is present. Dual Watch will resume if the
signal is lost for 3 seconds. To exit the Dual Watch mode, press the MON/
1/25 key to revert to the last used working channel or the 16/9 key to
revert to the programmed Priority channel.
Tri-Watch Mode
Tri-Watch monitors the selected working channel, the programmed Priority
Channel, and the last used Weather Channel for the Weather Alert Tone.
To initiate Tri-Watch, initiate the Dual Watch mode and press the WX/
INT key. The WX indicator illuminates on the LCD to indicate the Weather
Channel is also being monitored.
Operation is the same as Dual Watch except that if a Weather Alert Tone
is received, the radio simultaneously sounds an alarm tone, WX flashes,
and the NOAA Weather Alert is monitored.
To exit the Tri-Watch mode, press the MON/1/25 key to switch to the last
used working channel or the 16/9 key to switch to the programmed Priority
channel. To revert to Dual Watch mode, press the WX/INT key.
3.3.15 LCD Backlight Function
Pressing this key twice starts Dimmer mode, which adjusts the brightness
of LCD's backlight. Each successive press of the DIM key switches the
brightness from Off, to Low, to Medium, to High, then back to Off.
After the key has not been pressed for 5 consecutive seconds, the currently
selected brightness level is stored in memory.
