1. General Remote Control Units RM-29-A and RM-29-B are complete and self-contained units used for the remote control voice operation of certain types of radio sets (par. 3). Such additional equipment as auxiliary switches, externally connected batteries, or ground rods, is not required for operation. Remote Control Unit RM-29-A is furnished with Carrying Case CS-76-(*), and RM-29-B with Carry ing Case CS-76-(*). Two copies of TM 11-308 accompany each unit. There are no differences in the operation, dimensions, or electrical wiring of these units, but there are differences in the patterns for the placement of parts within the cabi nets. (See Figs. 3, 4, 5, and 6.) Space is provided inside Re mote Control Unit RM-29-(*)% for one Battery BA-27, but to avoid deterioration, this battery is not inserted until the unit is ready for use.


2. Equipment Used with Remote Control Unit RM-29-(*) For remote control of a radio set, the following items of equipment are used in conjunction with Remote Control Unit RM-29-(*) :

1 Battery BA-27 (to be installed inside Remote Control Unit RM-29-(*).

1 Headset P-19.

1 Microphone T-17.

1 Switchboard BD-71 or BD-72

or

1 Telephone EE-8-(*).


Sufficient two-conductor wire, such as Wire W-110-B, to connect the switchboard or telephone to Remote Control Unit RM-29-(*).


3. Use Remote Control Unit RM-29-(*) provides remote control voice operation of Radio Sets SCR-178, SCR-284-(*), SCR-299-(*), SCR-608-(*), SCR-609-(*), SCR-610-(*), and SCR-628-(*), and other models of similar design. The unit operates in conjunction with Telephone EE-8-(*) over a two-wire telephone line. Although control may be exercised only at the remote control unit, the ter minus for signals transmitted and received may be either Remote Control Unit RM-29-(*) or Telephone EE-8-(*). Microphone T-17 and Headset P-19 when plugged into Remote Control Unit RM29-(*) are used for transmission and reception of signals via the radio set, for monitoring signals between the telephone and the radio set, and for direct telephonic communication with Telephone EE-8-(*). The operational positions are selected by Switch SW-185 (Figs. 1 and 12) on the front panel of the remote control unit. The positions on the switch are marked RADIO, THROUGH, and TELEPHONE.


a. RADIO. —The radio set is controlled entirely by the operator stationed at the remote control unit. The operator transmits and receives signals using the radio set in the normal manner.

b. THROUGH. —The radio set is still controlled entirely by the oper ator at Remote Control Unit RM-29-(*). However, he can not transmit, but can only monitor the signals passing over the line, both from the radio receiver to any Telephone EE-8-(*) connected to the telephone line of the remote control unit, or from any tele phone to the radio transmitter.

c. TELEPHONE.—Remote Control Unit RM-29-(*) functions as a telephone, and the operator can communicate with any Telephone EE-8-(*) connected to the telephone line. However, neither the operator at the telephone nor the operator at the remote control unit can transmit to the radio.


4. Power Requirements One Battery BA-27 (4 1/2 volts) is required to operate Microphone T-17. The current drain from the battery is from 50 to 95 milliamperes, depending on the position in which the microphone is held.
