e. Press STO (Sto/ENT),
f. If press preset number.

h. When told by NCS, set PRESET switch to where ERF was stored.
Answer call from NCS for communications check.
2-26. CUE PROCEDURE.
Cue is used when it is necessary to contact an FH net of which you are not a member. It can be used if you miss
your primary nets opening. It can also be used to request entry into an alternate net.
The cue frequency must be loaded into CUE preset of net radio.
If using COMSEC equipment, set to plain text (PT) mode.
To cue an FH radio net:
Set PRESET switch to CUE. Make sure CUE preset is loaded (if not, use procedure in paragraph 2-14).
Press PTT for 4-6 seconds. Release PTT, return to cypher text (CT) and wait at least 15 seconds for
reply. If no reply, repeat this several times, then go to step c.
Set FUNCTION switch to SQ OFF; VOL control fully right. If radio has IFM power amplifier, set IFM
RF PWR switch to HI, Repeat step b as needed.
LATE NET ENTRY.
Two main methods can be used to join a net which is already operating such as recentering your own net after
leaving temporarily. Whether you use the Passive or Cue and ERF method depends upon two factors, ur-
gency of time and enemy EW capabilities.
Use the method which best suits your situation at the moment.
a. Passive Procedure. This method is preferred to join a net already established since it reduces SC risks
and does not add to the NCS work load. This capability is an integral feature of the SINCGARS radio.
