MAINTENANCE
When disassembling the main board
from the chassis, place the screwdriver's flat tip
as close as possible to the corner
of the main board (side 1). Failing to do so might damage
one of the components shown in the main board (side 2) details,
and thus cause transmitter performance degradation.
