The following are the precautions for handling the Q64TC.
(1) Do not drop the module casing or connector, or do not subject it to strong impact.

objects such as wire chips from entering the module when wiring. Do not remove
this film until the wiring is complete.
Before operating the system, be sure to remove the film to provide adequate heat
ventilation.
