■ With the 40W/50W radio, use a Torx T6 torque-driver to
tighten the two screws
C to 1lb·in (0.11N·m).
■ With the 25W radio, use a Torx T10 torque-driver to tighten the
two screws
C to 3lb·in (0.34N·m).
2. If the outer foam seal
E or the inner foam D-range seal G have been
removed, fit new seals to the heat-transfer block
F.
