[. . . ] Features include narrow-band operation, three channels, an external battery slot, reverse voltage protection, surface-mount components, and excellent lowvoltage operation. Plug plastics are included for compatibility with Futaba J, KO, JR and Airtronics (Sanwa) radios. The Polaris AM receiver already exceeds the stringent 1999 FCC specifications, and offers unmatched performance on the AM band. Congratulations on choosing the Novak Polaris AM receiver to guide you to the winner's circle! CHANGING THE INPUT PLUGS Instructions are listed below based upon the plug type of your radio system (servo, speed control, external battery pack). [. . . ] For On-Road Cars: Attach the antenna to a fiberglass antenna mast with several pieces of 1/4" heat-shrink tubing and let the excess trail off the top. Do not cut or coil excess wire, or range will be reduced.

STEP 4 HOOK-UP INSTRUCTIONS STEP 5 USING AN EXTERNAL RECEIVER BATTERY PACK PRODUCT WARRANTY Novak Electronics, Inc. guarantees the Polaris AM receiver to be free from defects in material and workmanship for a period of 120 days from original date of purchase (verified by dated, itemized sales receipt). Warranty does not cover incorrect installation, components worn by use, altering the antenna, exceeding the recommended input voltage, using the wrong crystal(s), improper use of external receiver battery pack, using the receiver without its case, tampering with the electronics, allowing water, moisture, or any foreign material to enter receiver or come in contact with the PC board, component damage due to excessive force, incorrect installation of alternate input plug plastic, or any damage caused by a crash. We reserve the right to modify warranty provisions without notice. MOTOR CAPACITOR & DIODE INSTALLATION Refer to Figure 6 1. To prevent radio interference, capacitors MUST be installed on EVERY motor. Solder the three included 0. 1µF (50 V), non-polarized, ceramic capacitors between: · POSITIVE (+) motor tab & NEGATIVE (-) motor tab. · NEGATIVE (-) motor tab & GROUND tab*. Extra 0. 1µF motor capacitors available in Novak Kit #5620. A 5-cell external receiver battery pack is recommended if erratic radio operation is experienced during hard acceleration. Because the speed control may be damaged by using an external receiver battery pack, we recommend you refer to your speed control's instruction manual for proper installation. If you will be using an external receiver battery pack, plug it into the BATT slot as shown in Figure 7. 2. An external Schottky diode must be used if the speed control's instructions indicate that one is needed. See the speed control's instructions for proper Schottky diode information and installation. Schottky diodes available in Novak Kit #5640. FIGURE 7 External receiver battery pack plugs into BATT slot. Because Novak Electronics, Inc. has no control over the connection and use of the receiver, no liability may be assumed nor will be accepted for any damage resulting from use of this product. Every receiver is thoroughly tested and tuned before leaving our facility, and is therefore considered operational. By the act of connecting and/or operating this receiver, the user accepts all resulting liability. Ground/Motor Can* 0. 1µF Capacitors Positive (+) Motor Tab Schottky Diode. [. . . ] The plating may have to be removed with a file. SERVO & SPEED CONTROL CONNECTION 1. When using a mechanical speed control or for gas models, plug the throttle servo into channel two. If you are using an external receiver battery pack, proceed to STEP 5. Otherwise, put tape or a decal over the BATT slot. FCC APPROVAL NOTE This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. [. . . ]
