3.7 Replacing the Circuit Board Fuse.
In cases where the radio fails to turn on when power is applied, the circuit board fuse should always
be checked as a probable cause of the failure. The locations of the fuse for both the UHF and VHF
boards are shown in Figure 3-1. The radio must be disassembled to replace the fuses as described in
the Basic Service Manual (see Chapter 1 - Related Documents), then the circuit board separated
from the radio chassis as described in the paragraphs that follow.
