TM 9-2350-275-BD COMMUNICATIONS SYSTEM Procedural Steps (Cont): 2. Plug the 5-pin connector into the RT-524 jack marked RETRANSMIT R/W. 3. Plug the lo-pin connector into the receptacle on the Number 2 TA-312. 4. Cut the required length of WI)-l/TT Field Wire (up to 15 miles). 5. Connect one end of the wires to line jacks 1 and 2 of TA-312 Number 2 and the other end to line jacks 1 and 2 of TA-312 Number 1. 6. Set the selector switch S 1 on both telephones to LB to enable DC switching from the push-to-talk switch. 7. Connect the DC plug from the remote unit into the BA4386/U battery. 8. Turn on all power. 9. Adjust the 5K ohm potentiometer so that the K-1 relay in the remote unit energizes when the press-to-talk switch on TA-312 Number is pressed. 10. Once this setting is found, the potentiometer should be backed off slightly to minimize battery drain. 11. Check all connections and test. 12. Record BDAR action taken. When the mission is complete, as soon as practicable, repair the vehicle using standard maintenance procedures. 11-35. GENERAL INTERCHANGEABILITY INFORMATION General Information: Repairs made to combat damaged equipment should be the same as repairs made during the normal maintenance posture. However, due to the extreme nature of damage that might be found in combat-damaged equipment, normal maintenance procedures might not be sufficient. In the interest of rapidly repairing damage to communications system in this situation, it will often be faster to exchange some components rather than repair them. The following is a partial listing of interchangeable parts for the AN/VIC-1 and the AN/VRC-12 as installed in most common tracked vehicles on the battlefield. It is provided as a guide only and is not necessarily a complete listing of all components from other vehicles that could be substituted. Further assistance can be obtained by studying the cording diagrams located in paragraph 11-36. This table considers only US equipment. For information on foreign equipment interchangeability, refer to paragraph 11-25 through 11-28. Any component that has been replaced should be turned in for repair through the normal channels and thereby returned to the inventory. When time permits, route all replaced cables to conform to the original configuration. If haste is essential, route replaced cables as necessary and secure them where possible to prevent damage to the cables. 11-49
