3.Attach the ZEQ25 Mount: Retract the Azimuth Adjustment Knobs to allow enough clearance for the Alignment Peg seating in the house. Put the mount onto the Tripod Head with Azimuth Adjustment Knobs on top of the Alignment Peg. Turn Center Rod Knob to secure the mount head onto the tripod. Tighten the Tray Locking Knob to fully expand the tripod legs and secure the Accessory Tray. Adjust the tripod legs to roughly level the mount using the built-in level indicator.

2.Setup tripod: Expand the tripod legs. Adjust the tripod height by unlocking and re-locking the tripod legs to desired height. Position the tripod so that the Alignment Peg faces north, if you are located at northern hemisphere. If you are located in southern half, face the Alignment Peg south. Thread the tripod center rod into the tripod head and install the Accessory Tray and tread the Tray Locking Knob onto it. Do not fully tighten the Tray Locking Knob.

The Alignment Peg may be moved to the opposite position shall the mount hit the tripod leg when used at a high latitude.

4.Adjust Latitude: Slightly loosen the Latitude Locking T-bolts. Turn Latitude Adjust Knob to adjust the latitude until the arrow points to your current latitude on the Latitude Indicator (see 2nd photo in step 1). Relock the Latitude Locking T-bolts.
