GENERAL INFORMATION The procedures in this manual cover the motorcycle installation of an S-825 Series Control Unit, a RANGR two-way radio, and associated items. The instructions in this manual are typical installation instructions, and are not intended to cover all makes and models of motorcycles available.

A typical S-825 Series Control Unit installation using a Harley-Davidson motorcycle Model FXRP is shown in Figure 1. EQUIPMENT Standard equipment available for the S-825 Series installation includes the following items: • One of the following S-825 Series Control Units -...
• Headset with Microphone, Handlebar Switch, and Belt-Mount Amplifier. CONTROL UNIT MOUNTING Mount the control unit within convenient reach of the operator, and where it will not interfere with the safe operation of the motorcycle. A typical control unit, microphone, and speaker mounting is shown in Figure 2. Due to the large number of different motorcycle makes and models, it is up to the installer to decide how to mount the control unit, radio, and optional equipment.

After all cables are installed, refer to the Control Unit Interconnection Diagrams in back of this manual for final connections to the control unit, and for instructions to install the cable entrance cover kit.

TWO-WAY RADIO MOUNTING The installation of the two-way radio consists of: • Mounting the base mounting plate to the motorcycle, • Installing the radio mounting bracket in the weatherproof case, • Installing the radio on the mounting bracket, and • Connecting the power/control cable, cable ground lead, and antenna lead once they have been installed.

SERVICE TIP After installation, force full compression of the shock absorbers and observe the ground straps. If necessary redress the ground straps to a position that allows full compression without pinching. (Clearance is reduced from 5/8” to approximately 1/4”.)

Installing The Weatherproof Box 1. Install the weatherproof case base mounting bracket (19C337200G1) to the motorcycle mounting bracket (customer supplied and installed) with the four 1/4 X 20 X 3/4 inch cap screws and lock nuts provided. See Figure 5. NOTE If the Rear Mount Antenna Option is used, refer to the antenna installation procedures and install the antenna...

Figure 6. Radio Top Mounting Bracket Installation NOTE If you are installing a radio that has not been modified motorcycle applications, refer “Radio Modification Procedures” and modify the radio before continuing. 4. Refer to Figure 7 and position the radio and top mounting plate assembly over the bottom mounting plate.

Figure 7. Radio and Base Plate Mounting Radio Modification Procedures NOTE Applies only to radios that have not been modified for motorcycle applications. Prior to installing the radio in the weatherproof box, the radio must be modified to withstand the mechanical vibrations inherent to motorcycle applications.
8. Remove the wire metal handle (if present) from the 13.2 Mhz plug-in reference oscillator located on the synthesizer board. 9. The logic board in the top of the RANGR radio contains one or two plug-in crystals. One of these is located under the removable metal shield.
damage may result. Also, route the cables so that they will not interfere with the operation of the motorcycle. Secure all cables with black cable ties for a neat installation. POWER/CONTROL CABLE The power/control cable is supplied for negative ground systems only. It is recommended that the black fuse holder box shipped with the radio be discarded and the black weatherproof fuse assembly provided be used in this installation.
Page 17
11. Install a new ring terminal on the black cable and connect it to battery minus (-). NOTE Any extra length of the power/control cable can be coiled under the motorcycle seat and secured to prevent interference with the operation of the motorcycle. See Figure 10.
VEHICLE SYSTEM CABLE The vehicle system cable provides power to the control unit. The yellow-fused lead provides the receiver "hot" and transmitter enable connection. The black lead provides the control unit ground. An optional red-fused lead (Option CC01) is available for ignition switch standby control.

Installation Notes: Figure 10 shows the use of a customer- fabricated, under-seat mounting plate. This mounting plate provides mounting holes and slots for securing connectors, fuses, and cables on some Harley-Davidson motorcycles (such as model FXRP) . The mounting plate is especially helpful for large installations. In addition, banana plugs may be installed in the power cables as shown in Figure 10 to provide for quick connections to a battery charger, if desired.
c. Before replacing the fairing, the vehicle system cable and any option cables may be run under the fairing also. Then replace the fairing by removing the gas cap, repositioning the fairing, then replacing the gas cap and the three screws that secure the fairing. For motorcycle models not equipped with a gas tank fairing: After making power connections, run the power/control and vehicle system cables (as well as any option cables) up the left side of the motorcycle to...
SPEAKER MOUNTING Mount the speaker where the operator can hear it, and where it does not interfere with the safe operation of the motorcycle. On some motorcycles, the speaker can be attached to the windshield bracket using existing bolts to secure the speaker mounting bracket (see Figure 2). CONTROL UNIT CONNECTIONS After installing the control unit, speaker, and all cables, connect the required leads (including option leads) to the vehicle system plug as shown...
ANTENNA INSTALLATION TOP COVER POSITION The antenna must be installed in accordance with good engineering practices for best results. See Figures 14 and 15. Mount the antenna in the 3/8 inch hole provided in the top of the weatherproof case according to the antenna manufacturer's instructions with the following exceptions: 1.
Figure 16. Antenna Mounting (Rear Mount Option) FINAL CHECKS AND CONNECTIONS After the weatherproof case is installed and all cables run, connect the power/control plug to the radio, connect the antenna to the radio, and connect the cable shield ground to the radio case with the metric screw provided with the Power/Control Cable as shown in Figure 17, Radio Connections.
HEADSET OPTION INSTALLATION Headset option includes the helmet-mounted microphone, amplifier belt, and cables with quick disconnect connectors. A typical installation is shown in Figure 18. Install the headset option according to the manufacturer's instructions provided with the option. Figure 18. Typical Headset Installation...
