Unit Installation

Installing the Unit on the Mounting Bracket
1. Align the slot on the back of the unit with the long mounting knob and slide in place. It may be
necessary to adjust the long mounting knob to spread the bracket arms apart. Turn counter-clockwise
to widen the bracket arms, clockwise to tighten.
2. Adjust the unit angle and tighten the long mounting knob until snug.
3. To tilt the unit, loosen the long mounting knob on the right side of the bracket assembly.
4. To rotate the entire bracket, twist it left or right. The bracket clicks as you turn it.
5. Tighten all knobs once the desired viewing angle is obtained.
