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. In no case shall our liability exceed product's original cost. 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. · POSITIVE (+) motor tab & GROUND 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. There are a few methods of using an external receiver battery pack. 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. Never use a Schottky diode with a reversible speed control. 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. [. . . ] 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. These limits are designed to provide reasonable protection against harmful interference in a residential installation. [. . . ]
