6.3 Working Channel Recall
Rather than using the
SELECT/ENT
knob or microphone keys to change chan-
nels, this feature allows quick switching between the last working channel
and the current primary channel.
To quickly switch between the last working channel and the Primary Calling
Channel:
•
Use the
SELECT/ENT
knob or microphone keys to select a working chan-
nel, such as channel 68.
•
Press the
16
key momentarily. The current primary channel number
appears in the channel number display.
•
Press the
16
key again momentarily. The working channel number
appears in the display. Each time the key is pressed, channel selection
toggles between the primary channel and the working channel.
6.4 Transmitter Power Setting
The transmitter has two power settings, 25 watts or 1 watt, which are indi-
cated by
HI
or
LO
appearing in the upper line of the display. The normal
power setting is
HI
for all channels where 25 watts is allowed. Use the 1 watt
setting for communication with nearby vessels (bridge-to-bridge) or facilities
(drawbridges).
•
Press the
H/L
key to toggle transmitter power between 25 watts and 1
watt output.
SPECIAL NOTE
Channels 15, 17, 75 and 76 are restricted to 1 watt maximum power and
will cause the error beep if the
HI/LO
key is pressed.
6.5 Channel Scanning
There are three channel scanning modes; Priority Scan, All Scan and Memory
Scan. In the Priority Scan mode, Channel 16 is checked for activity every 2
seconds, even if, the scan is halted by traffic on a working channel. When
scanning is halted by traffic, the scan pauses while the channel is active.
Scanning resumes, after a brief delay when the channel is clear. If the
PTT
is
pressed, in reply to a received signal, scanning is cancelled.
