User manual ACR ELECTRONICS L-32 FIELD MARKER LIGHTING SYSTEM

[. . . ] The ACR Field Marker System was used during Operation Desert Storm, a testimony to its readiness, versatility and reliability. Although the need and the concept had developed from a specific combat situation, ACR's Field Marker Systems can find applications in other areas as well, using either remote control or manual activation. The system can be used for rescue missions by special forces or as a portable landing system in place of costly permanent air field systems; in military situations, the system can help guide cargo aircraft for supply drops or deploy airborne forces. The remote control switching module of the Field Marker Light Systems can be readily adapted to any situation requiring a remote controlled electrical on/off function. [. . . ] The ACR/L-32RCL is plugged directly into the battery, the switch is designed to change the light from "Remote Controlled Mode" to "Manual Mode". The Model ACR/CC-1 Code Controller (See Figure 4) The ACR/CC-1 Code Controller is designed to interface with the PRC-77 Handset Microphone. It is a hand held tone generator which is used to send tone codes through the PRC-77. When using the ACR/CC-1, place it in direct contact with the microphone of the handset. PRC-77 or an Equivalent FM Transmitter Shall be capable of transmitting FM signals on frequency of 46. 75 MHz. (Not provided) Figure 2 ACR / L-32 RC Remote Control 4 Y1-03-0116 Rev. C 4. 0 SYSTEM SET-UP AND OPERATION A) Manual Activation 1) Insert the ACR/L-32 or ACR/L-32 RCL Light into a BA-4386 or BA-5598 Battery. 2) Press the Push-ON, Push-OFF switch for the desired position (light will turn ON or OFF accordingly). (Each light must have its own battery. ) Figure 3 ACR / L-32 RCL Remote Controlled Light B) Remote Control Activation of the ACR/L-32, ACR/L-32RC Combination (See Figure 5) 1) Set the ACR/L-32 to ON position (see steps 1 and 2 of Manual Activation). 2) Insert the ACR/L-32RC Remote Control in between the light and the battery. 4) Secure the complete assembly of the light, the remote control and the battery together with the canvas strap, and secure it to the ground with long nails or stake-down pins. 5) At a remote location (up to 5, 000 feet away from lights), set the frequency to 46. 75 MHz on the PRC-77 or equivalent. 5 Y1-03-0116 Rev. 7) Turn the ACR/CC-1 ON and position it next to hand-set of the PRC-77, make sure the microphone of the ACR/CC-1 is facing the microphone on the hand-set. 8) On the key pad, press button number 1, 2, or 3 to turn light(s) ON, or press button number 4, 5, 6, or 7 to turn light(s) OFF (see Note 2). Note 1: Pressing button number 7 on keypad will always turn OFF all lights regardless of their code configuration. Note 2: The codes on the ACR/L-32RC Remote Control and the ACR/L-32RCL Remote Controlled Light are factory set to these values, however, other code combinations are available. For further information, please refer to section number 5, Customizing the Activation Code. Figure 4 CC-1 Code Controller 6 Y1-03-0116 Rev. C Figure 5: ACR/L-32 / L-32 RC Combo Remote Light System C. Remote Controlled Activation of the ACR/L-32RCL unit (See Figure 6) 1) Insert the ACR/L-32RCL Remote Controlled Light directly into the battery. 3) Secure the complete assembly of the light, and battery together with the canvas hold down strap and secure the light to the ground with a long nail or stake down pins. 4) At a remote location (up to 5'000 feet away from the lights), set the Field Radio (PRC77 or equivalent) to 46. 75 MHz FM. 5) Turn on the CC-1 and position it to the mouthpiece of the Field Radio hand set. (Position speaker of CC-1 to microphone of handset) 6) Press the desired code (an audible tone should be heard) then press the Push to Talk switch to transmit the code. [. . . ] Each selected code number may be used for one function only, "ON" or "OFF". C) Setting the "ON" code selector Set the DIP switches of the "ON" code selector to the "ON" position for desired "ON" activation code. Set all other DIP switches to "OFF" position. 9 Y1-03-0116 Rev. C ON ON Example 1: Light shall turn "ON" when code 1 is selected. [. . . ]
