RIT RADIO SELECTION SWITCH SETTING PROCEDURES (FIG. 2-38.)

Perform the following procedures to set the Radio Selection Switch on RIT.

NOTE

The following procedures can only be performed when the RIT is dismounted.

a. Remove the switch protective cover from rear plate of RIT using a spanner wrench, and rotating

counterclockwise.

b. Using a jeweler's screwdriver turn switch counterclockwise to stop, this sets the RIT to Radio's

C/D.

c. Turning the switch clockwise one position sets the RIT to center position. This position is used for

testing, however, if the MCS is not functioning correctly, e.g., loss of timing signal (sync pulse),

but is supplying power to the rest of the system, setting the switch to this position will result in the

RIT putting out a timing signal like the MCS.

d. Turning the switch clockwise one more position sets the RIT to Radio E/F.

e. When the correct Radio setting position for the RIT has been made, replace switch protective

cover using spanner wrench and tighten.
