Make sure the routine checks are done on the following items
(refer to TM 11-5820-890-10-1 for more information):
Cables and cable connectors.
Controls and switches.
Mounting and assembly hardware.
Check battery life condition (refer to TM 11-5820-890-10-1).
If FCTN is at OFF, move it to STBY; then move it to SQ ON.
Check required load.
(Do you have the correct hopsets, lockout sets,
COMSEC keys, cold start TSK, CUE frequency and MAN frequency?)
Stand by for net opening (the NCS contacts you). Make sure you can
establish communication on each net you are operating in.
Your rt needs special data to operate in a frequency hopping (FH) mode. Net
opening is the procedure for loading this data. Always keep in mind that your
NCS directs net opening and that you must listen to his commands carefully.
There are two procedures for net opening: (1) cold start net opening and (2)
time hack net opening.
The NCS will tell you which one to use. If Net is to
be opened in CT, refer to the BASIC COMSEC PROCEDURES in this section (pages
J-n to J-13.
COLD START NET OPENING
NOTE: The following steps are designed for net members. Detailed NCS
procedures are provided in manual TM 11-5820-890-10-1 Chapter 4.
Make sure that your rt has FH data loaded (the NCS has the same data
loaded in his rt):
Cold start TSK in channel 1 or MAN channel (automatically
loaded into MAN channel when hopset is loaded into channel
