TM 9-2350-273-BD COMMUNICATIONS SYSTEM Procedural Steps (Cont'd) NOTE The Allied countries listed in the table have agreed to utilize the same connectors for cables within the radio system. All power cable connectors should be the same regardless of which country's radio is examined. 2. Remove the radio and its accompanying mount from the foreign vehicle. Note which cable connector supplies power to the mount. 3. Remove the radio and its accompanying mount from your vehicle. Note that the power cable is J-21. 4. Install the foreign vehicle radio and mount in the place vacated by the US AN/vRC-12. 5. Install the cable that previously ran to 3-21 in the connector socket for input power on the foreign radio mount. 6. If the foreign vehicle had an intercom system, hook up the cable that runs between J-22 on the U.S. radio mount and 3-501 on the AM-1780. This cable must be hooked up to the same connections to which the foreign vehicle intercom master control box was connected. 7. Be sure to take one foreign vehicle CVC helmet for use in case the U.S. CVC helmet will not adapt to the front of the foreign radio. Prior to using the foreign CVC helmet at the radio face, attempt to operate the radio through the AM-1780. If the AM- 1780 does not key the foreign radio then there is a wiring difference and the foreign CVC helmet can be connected directly to the microphone input connection on the front face of the foreign radio. 8. Record the BDAR taken. When the mission is completed, as soon as practicable, repair tank using standard maintenance procedures. 11-28.
