(b) If the fault continues:
- remove the same RMP
- do a check and repair if necessary the wiring of the VOICE/DATA SELECT OUTPUT from the pin A/G of the RMP to the RMP derivation terminal block (Ref. ASM 46-21/05)
(c) If the fault continues:
- do a check and repair if necessary the wiring of the VOICE/DATA MONITOR INPUT from the RMP derivation terminal block to pin A/F of the RMP (Ref. ASM 46-21/05)
- install the RMP that you removed.
(2) If you cannot set the DATA mode on the two other RMPs:
(a) Remove the ATSU (1TX1) (Ref. AMM TASK 46-21-34-000-001)
- do a check and repair if necessary the wiring of the REMOTE VOICE/DATA SELECT from pin AA/15A of the ATSU to the RMP derivation terminal block (Ref. ASM 46-21/05)
(b) If the fault continues:
- do a check and repair if necessary the wiring of the PORT SELECT DISCRETE from AA/12B of the ATSU to the RMP derivation terminal block (Ref. ASM 46-21/05).
(c) If the fault stops:
- install the ATSU (Ref. AMM TASK 46-21-34-400-001)
(d) If the fault continues:
- install a new ATSU (Ref. AMM TASK 46-21-34-400-001).
B. Do the test given in Para. 3.A.

3. Fault Confirmation
__________________
A. Test
(1) Do the operational test of the ATSU (Ref. AMM TASK 46-21-00-710-001) from the step 35. Do it again for each RMP.
4. Fault Isolation
_______________
A. If you cannot select the VOICE mode from one RMP, do the fault isolation procedure that follows:
(1) If you can correctly set the VOICE mode on the two other RMPs
(a) Replace the RMP-COM/NAV FREQ SEL, 1 (1RG1), RMP-COM/NAV FREQ SEL, 2 (1RG2) or RMP-COM FREQ SEL, 3 (1RG3) on which it was not possible to set the VOICE mode (Ref. AMM TASK 23-13-13-000-001) and (Ref. AMM TASK 23-13-13-400-001).
