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.
30 Remove the radio and its accompanying mount from your vehicle. Note that the
power cable is 3-21.
Install the foreign vehicle radio and mount in the place vacated by the U.S.
4.
AN/VRC-12.
5. Install the cable that previously ran to J-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 connected
to the same connections to which the foreign vehicle intercom master control box was
connected to.
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 connector on the
front face of the foreign radio.
