Mounting
Mounting the bottom case
● Tighten the screws securely until the screw heads touch the bottom case.
( Otherwise, loose screw heads may hit the PCB and cause malfunction
when mounting the top case.)
● Do not over-tighten the screws.
( The bottom case may be deformed, resulting in the unit becoming
detached from the surface it is fi xed to.)

securely from the insertion slot and release the push button.
● Pull the wiring lightly, and confi rm it is secured.
