RCAUTION

1. When re-assembling the case and tightening the

screws, you must keep the specified torque
(0.7±0.1 N.m). Otherwise the transceiver may be
damaged (torque too high) or lose waterproof effi-
ciency (torque too low).

2. When uninstalling the optional unit, remove it ver-

tically. Wiggling the unit from side to side may
damage the optional unit's connector.
