Dear Half-Mast,

I’m testing a SINCGARS RT-1523F on an AN/GRM-22 and the radio is failing LIT 797 AUX DISPLAY. When searching through TM 11-5820-890-13&P-5 (Aug 14), I can’t find that specific LIT number anywhere.

I’m assuming that the display needs to be replaced, but without the TM confirming my suspicion, I can’t be 100 percent sure. Is my TM out of date?

Dear Specialist,

No, you’ve got the right TM. WP 0701 of TM 11-5820-890-13&P-5 contains the field troubleshooting procedures operational check for the receiver-transmitter RT-1523F(C)/U.

You'll find step-by-step field troubleshooting procedures for AUX DISPLAY CHECK (LIT 797) in Step 45 in WP 0701-15.
