7.5.3 Receiver Repairs
Patriot receivers have been designed for the utmost reliability. Other than two fuses to protect the basic power
circuits, there are no serviceable items in the receiver.
7.5.4 Fuse Replacement
See Figure 8.
1. Ensure power is switched OFF to all receiver power inputs.
2. Remove the mounting bolts from the end of the receiver by the interface cable.
3. Remove the four screws on the end of the receiver near the interface cable.
4. Gently pull the end cap and receiver board out of the case about one inch so that the fuses on the bottom
edge of the circuit board are exposed.
5. Using a voltmeter, verify that no power is present on either of the fuses.
6. Replace the appropriate fuse with a GMC 125V 10A M/D or equivalent fuse 125VAC for F1 or F2. For F3
use 250V/250mA.
7. Reposition the end cap and insert and tighten the four screws snugly.
8. Replace the mounting bolts to the end of the receiver by the interface cable.
