8. Weather
Alert
Indicates that the radio is monitoring for weather alert broadcasts. US and
Canada only.
9. (U, I, C, WX) Channel Set
Indicates which channel set is selected: U (USA), I (International), C (Canadian), or
WX (Weather).
Note:
Special licensing is required to receive the US and Canadian channel sets.
10. (A, B) Channel Status
A subscript character following the channel number indicates special qualities.
(A) Simplex Channel
The subscript
A
indicates that the currently-selected US or Canadian channel is
simplex, although its International counterpart is semi-duplex (5A, for example).
This channel uses the transmit frequency of the International channel for both
transmitting and receiving. If a channel is simplex in all 3 channel sets (US,
Canadian, and International—channel 6, for example), the
A
does not appear.
Note:
Simplex means that the radio transmits and receives on the same frequency for this
channel. Semi-duplex channels use separate frequencies to transmit and receive.
(B) Receive-only Channel
The subscript
B
indicates that you cannot transmit on the currently-selected
channel; it is receive-only. Used with Canadian channels only.
11. Channel Number
Displays the current active channel number.
12.
Battery Voltage Alert
The Ray49E is designed to be operated on a 12 volt (nominal) system. If the boat’s
battery voltage drops below 10.5 VDC or increases above 15.8 VDC, the battery
icon appears with the message BATTERY LOW or BATTERY HIGH, respectively.
13. Dot Matrix Display
Indicates radio functions, GPS position data or special conditions, depending on
the situation. The screen is different when sending/receiving a DSC Call (see
Chapter 5) or setting up a Menu item (see Chapter 4). The top line usually displays
the current channel name. This field is editable.
