VUHF [1L]:
Display and modify the active/standby preset number and frequency/channel of the VUHF radio.
Entry from the keyboard is validated and then the frequency and preset/channel, if available, are placed in the
standby field below the active field, otherwise an error message is displayed in the scratchpad. Preset and
channel are displayed in small font green color. Maritime channel numbers are shown in the form CXX (where
XX=the maritime channel number).
Additionally, guard and emergency 243 activation will be shown next to the text VUHF. To indicate activation of
these, GUARD and EMER, respectively, will be displayed just next to the title text VUHF in inverse white font to
inform the crew of the selection of these prompts.
NOTE:
•
It is possible to have dashes "-" in one or both of the active and standby fields after FMS maintenance.
Toggling is not allowed when "-" are present in the standby field. At that time, a frequency/channel needs to
be entered in the standby field first before the active/standby field toggling is allowed, otherwise a warning
message will be displayed in the scratchpad.
•
If a maritime channel is entered while in either MAR SHIP or MAR COAST, then this has no effect on the
MAR TYPE setting (e.g. the existing setting is retained).
TUNE GUARD [2L]:
Selection of this prompt will tune the radio to emergency frequency corresponding to the
currently active frequency band. That is, once this prompt is selected, the active frequency will be commanded
to either 40.500, 121.500, 156.800 (“C16” will also be shown in preset field), or 243.000 MHz (see table of
Figure 13-4), and the previously active frequency will be moved into the standby field. The receiver mode (RX
MODE) will also change to TR and “GUARD” will be annunciated next to the text at LSK 1L/1R as well on the
corresponding V/UHF radio’s line on the top RADIO page (e.g. RADIO 1/X or 2/X).
Also, once this prompt is activated, the prompt itself is removed from view until the operator makes another
V/UHF radio parameter selection which causes the guard state to no longer be maintained.
When TUNE 243 is activated this prompt is removed from view and unavailable for selection.
MODE
[3L]:
Possible options are AM, FM, MAR SHIP, and MAR COAST. Depending on the frequency field
value entered, the mode displayed can be either AM or FM. The crew will need to toggle this prompt to enter a
maritime channel based mode of operation.(e.g. MAR SHIP or MAR COAST).
The possible MODE options for the various frequency bands shown in the table shown of Figure 13-4 are
described here:
•
when the entered active frequency lies within a frequency range having only AM as a possible
modulation, the MODE will change to "AM".
•
when the entered active frequency lies within a frequency range having only FM as a possible
modulation and is not a maritime band frequency having an associated maritime channel, the
MODE will change to "FM"
•
when the MODE is AM or FM, the crew may at any time toggle this prompt to enter the maritime
mode.
•
while in the maritime mode (MAR SHIP or MAR COAST), if the crew enters a frequency which
exists in the table of figure 13-5, the FMS will automatically display the corresponding maritime
channel and maritime type (SHIP or COAST) for the selected frequency; otherwise, if the frequency
is not in the table, the FMS will set MODE to be that corresponding to the entered frequency’s
modulation.
•
when the active frequency lies within a frequency range having either AM or FM, MODE will remain
unchanged from its current setting.
•
when entering the maritime mode, the VUHF LVL setting will only be LOW PWR or MED PWR.
RX MODE [4L]:
Toggles and displays VUHF receiver mode options. The possible values are: TR, TR_G
