The desk installation for the 55i IP phone consists of two legs that attach to the back of the phone near the top corners. A total of four different viewing angles allows users to personalize their phone viewing preference. Attach each leg by inserting the tabs on the leg into the slots on the bottom of the phone. There are three pair of leg slots on each corner of the phone; each leg uses two pairs (1&2, or 2&3) giving two leg positions designating different viewing angles. Furthermore, the legs can be reversed which offer two additional viewing angles. For a higher viewing angle, use the second and third slots from the top. For a lower viewing angle, use the first and second slots from the top. Then push the stand towards the phone until it snaps into place.
