Remove the CX-13061/U from the J3513/U J3 and remeasure J5 pin A
to B.
If the measurement is more than ten ohms, the CX-13061/U is bad.
Send to COMSEC maintenance for repair.
If the measurement is less than ten ohms, the J-3513/U is bad.
Send to COMSEC maintenance for repair.
g. Test procedure 43. When checking the J-3513/U J5 pin A to pin B and
the circuit is not shorted, an open exists within the phone audio out
circuit.
To check for an open in the phone audio out circuit, remove the
RT from the MT-1029 and measure continuity on the MT-1029 J24 pin
S to the J-3513/U J5 pin B.
If 1100 to 1300 ohms is measured the RT is bad.
Send to IDS for
repair.
If infinity is measured, disassemble the MT-1029 mount and remove
P1 of the J-3513/U from J22.
Measure continuity on the MT-1029 J24 pin S to J22 pin H.
If zero ohms is measured the J-3513/U is bad.
Send to COMSEC
maintenance for repair.
If infinity is measured, the MT-1029 is bad.
Send to IDS for
repair.
h. Test procedure 44. During EPC step 6, there is no rushing noise at
the J-3513/U J5 after you have moved the handset to the RT SPKR jack (Test
procedure 39).
Remove the CX-13064/U from the RT X-MODE jack.
Replace the X-MODE cap on the RT X-MODE jack and listen for
rushing noise.
If no rushing noise is heard, a short on the phone audio out
circuit may cause this problem.
To check a short on the phone
audio out circuit, turn the RT off.
Remove the RT from the MT-1029.
Measure continuity on the MT-1029 J24 pin S to pin A.
If the measurement is more than ten ohms, the RT is bad.
Send to
IDS for repair.
