SINCGARS, select the type of ERF by toggling the line
select key between the following:
1. RECV HOP (Receive Hopset).
2. RECV LOCK (Receive Lockout).
3. SEND HOP (Send Hopset).
4. SEND LOCK (Send Lockout).
Enter the hopset or lockout number at line select
1R, and select line select 1R once more to activate the
ERF. Valid hopsets will be 1 - 25 and valid lockouts
will be 1 - 8.
(p) Late Net Entry. To access a
SINCGARS net that has already been established,
press line select key 2L. The hopset and lockout
variables must already be established to allow entry
into the net. Late net entries will be enabled or
disabled as long as the radio is not the net master.
(q) Time Sync hronization. To update the
time synchronization of the SINCGARS net as a
Station Master, enter a day/time for synchronization at
the appropriate line select key. The correct entry
format is DDHHMM, where DD is the date (range 0
99), HH is the hour (range 0 23), and MM is the
minute (range 0-59). With a blank scratchpad, the
CDU will request a current time synchronization from
the V/UHF radio and display the synchronized time.
(r) Net Control Station Master Selection.
If the V/UHF radio has been designated as the master
control station radio, select MSTR to enable the
master synchronization of all net radios from this radio.
The designated radio must be operating in an anti-jam
mode when selected.
(s) V/UHF Cue/Cold Page. The V/UHF
cue/cold page may be accessed from the V/UHF
SINCGARS Control page or the Communications page
if the V/UHF radio is tuned to the cue or cold preset
Figure 3B-128 and Table 3B-92.
(t) Cold Start Operation. To initially
open a SINCGARS net, enter a cold start frequency
and select that frequency. The cold start frequency
will be enabled on the Communication page. To
activate the net, use the ERF set-up procedures as
described above and synchronize the net radios.
(u) Cue Operation. To enter an active
SINCGARS net, enter the cue frequency and select
that frequency. The cue frequency will be enabled on
the Communication page to allow entry into the
(3) Head-Up Communication Radio Data.
The FDS-255 provides the pilot heads up display of
the V/UHF communication radio data on the Flight
Display Free Format Line (FFL) as shown in Figure
3B-129 and Table 3B-93. The current tuned callsign
and frequency are displayed in green on the left side
of the FFL. The previous tuned callsign and frequency
are displayed in cyan on the right side of the FFL. An
external push button (quicktune push button) located
on the pilot and copilot control yokes, is dedicated for
remote communication radio frequency control.
