Replacement
NOTE: Because of the delicacy of this procedure, we recommend you contact your
distributor before trying to replace the Battery.
Mounting the IXP20 Controller
CAUTION: Make certain that you mount the Controller on a vibration-free
surface.
NOTE: You can mount the IXP20 Controller onto virtually any surface including
metal.
Select the mounting position of the IXP20 Controller, considering accessibility, routing
of wires and visibility of the Thin Film Transistor Liquid Crystal Display (TFT-LCD) and
accessibility of the Keypad.
Secure the enclosure to the mounting surface, using four suitable screws and wall
plugs, nuts and bolts or rivets.
