To set up and level the iOptron HEM27 HEM Hybrid Strain Wave GoTo Equatorial Mount, follow these steps:

1. Set up the tripod: Start by setting up and leveling the tripod. Adjust the tripod height and tighten the locking xxxx to secure it. Thread the Alignment Peg onto the tripod head, either using a threaded hole on top of a tripod leg or between two legs for low latitude.

2. Attach the mount head: Retract the 2x Azimuth (Azi) Adjustment Screws from both sides to leave space for the alignment peg. Remove the 2x Azi Locking Screws from the mount base. Secure the mount head by tightening the Azi Locking Screws into the M6 holes on the tripod. Use the built-in Bubble Level Indicator or an external leveler to level the mount.

3. Adjust the latitude: Loosen the 4x Latitude Locking Screws slightly. Use the Latitude Adjustment xxxx to set the correct latitude value, as displayed in the Latitude Mark Window. If more turning torque is needed, insert the Allen wrench into the Latitude Adjustment xxxx .

4. Switch the latitude range: The mount head can be set up for two latitude ranges, 15~41° and 39~65°. To switch the latitude range, follow these steps:
a. Loosen the Latitude Locking Screws just enough to adjust the latitude setting to between 39～41°. Tighten the Latitude Locking Screws.
b. Unthread and pull out the Position Bolt. Remove and keep the two black tubes. Insert the Position Bolt to a new latitude position with one black tube on.
c. Adjust the Latitude Adjustment xxxx while holding the bottom brass eyebolt until it lines up with the Position Bolt. Insert another black tube and secure the Latitude Position Bolt.
d. Move the Latitude Locking Screws to the new locations revealed.

5. Install the telescope: The HEM mount accepts a Vixen or a Losmandy-D dovetail mounting plate. Release the dovetail Saddle Locking Lever and slide the telescope dovetail plate into the saddle with the Gear Switch disengaged. Ensure that the arrow sign on the saddle is pointing forward. Tighten the Saddle Locking Lever and position it parallel to the saddle to prevent interference with the DEC unit during mount GOTO and tracking.
