2.2f. RT Messages

"CALL'

This message appears in the display of a remoted radio when an RCU(RT)

operator presses the CALL key, and at the RCU(RT) when the remoted radio

operator presses the CALL key.

"EXT"

If your radio has been set to EXT, as an option of the RCU key menu, an

" XT" message will be displayed. All RT front panel controls except

COMSEC are disabled. Unless you want to use the EXT feature, use the

RCU key to turn EXT mode off. The ASIP RT is always in an EXT mode as

long as it detects proper interface and software, EXT will not be displayed.

If a " ail 5"message is displayed during power-up and BIT, it means one of

"Fail 5"

three things:

(1) You have an ANCD or other fill device connected to the RT.

Disconnecting the fill device will correct the FAIL 5 situation.

(2) You have mistakenly set the COMSEC switch to Z. Moving the

COMSEC switch to another position will correct the FAIL 5 situation.

(3) The RT tamper switch has been activatedor there is a hard COMSEC

failure, in which case you need to see your unit maintainer.

"Fail 6"

This message applies to INC and HFMUX failures.

When GPS time has been successfully loaded into the SIP/ASIP radio, the

"G"

letter " "will be displayed. When a radio loaded GPS time is returned to SQ

ON from STBY, a blinking " " indicates that GPS time needs to be reloaded.

Disappearance of the " " indicates that the radio is no longer using GPS

time.

"GOPT"

Indicates that the SlP/ASlP radio has experienced a COMSEC failure;

operator must change to PT in order to continue to communicate.

"GOTST"

When this message appears, it indicates a COMSEC problem. The radio will

not transmit, receive, or fill until BIT has successfully run. If you cannot get

the RT to run BIT successfully, action by unit maintenance is needed.

"NOGPS"

This message appears when attempting to load GPS time without a GPS

device (PLGR) attached.

"NOKEY"

If you power-up your radio in CT when there are no COMSEC keys loaded,

a " OKEY"message will be displayed and a COMSEC alarm will be heard.

Setting COMSEC to PT or loading a COMSEC key will clear the alarm.

"PT RX"

This message will be displayed whenever you have your radio in CT and

receive a PT message.

"SETDR"

For transmission operation, this message tells the RXMT operator who

selects RS-232 that an EDM data rate (1200N, 2400N, 4800N, or 9600N)

must be selected before RS232 transmissions can be started. (NOTE: All

SIP/ASIP radios using RS232 mode must be set to the same EDM data rate.)

"WAIT"

This message is displayed while BIT is running, changing to the message

" OOD" when BIT is successful.
