Installation

This chapter describes the panel function and installation procedure for
the U-336S/SA.
A shielded RS-232 cable is required to ensure compliance with FCC
Part 15, and it is the responsibility of the user to provide and use a
shielded RS-232 cable. Make sure your installation site is clean and
well ventilated. The ventilation slot of your ZyXEL modem located on
the sides and bottom should not be covered and should allow free
movement of air.
