TM 11-2650 C1 TECHNICAL MANUAL MODULATOR MD-69/FRT CHANGES No, 1 TM 11-2650, 19 November 1945, is changed as follows: Title is changed to read: Modulator MD-69/ FRT. 32. Relays (Superseded) a. The proper operation of the relays in the aux- iliary relay unit (Wilcox Electric Type 169D) and the dialing unit (Wilcox Electric Type 168C) is essential for trouble-free operation of Modulator MD-69/FRT (Wilcox Electric 50A and 50A3), when dialing from a Remote Control Console CY- 161/FRC (Wilcox Electric CS212) or from a local position. Unsatisfactory mechanical and/or elec- trical condition of the relays (primarily control relay S2 in dialing unit 168C) may result in severe damage to Modulator 50A-10 which is part of Modulator MD-69/FRT. b. Dialing unit type 168C provides relay and switching circuits for remotely and locally con- trolling 10 radio transmitters for phone operation.
