5.2.2 Removing the Covers

Figure 5-2: N-20 Covers with the PCB and Display Assembly

1. Remove screw cap (30), and loosen the captive screw (31), which secures the rear cover (15).
2. Separate the front cover (16) from the rear cover by wedging a thin flathead screw driver between
the covers at the base of the instrument and slowly prying them apart.
Note: The covers are hinged at the top end in a different way; do not attempt to
separate the covers using this technique at the top of the instrument. Once the covers
are separated at the bottom end, lift away the bottom end of the front cover first,
allowing the tabs at the top end to act as a hinge.
