5.3 Replacing the Installation Gasket
The installation gasket provides protection against dust and moisture.
 Installation Gasket Attachment Procedure
(1) Place the OT on a flat, level surface facing the display face downwards.
(2) Remove the gasket from the OT.
(3) Attach the new gasket to the OT. Be sure to insert the gasket into the OT’s groove so that the gasket’s
groove sides are vertical.
(4) Check that the gasket is attached correctly to the OT.
• A gasket which has been used for a long period of time may have scratches or
dirt on it, and could have lost much of its water resistance. Be sure to change the
gasket at least once a year, or when scratches or dirt become visible.
