## Step 5: Check latitude range on mount

The iOptron CEM40 mount has two latitude ranges, 0—35° and 25—60°.

Pick the latitude range most suitable to your site's latitude. To change the latitude range, unthread and remove the 'position bolt' to its new location. Adjust the 'latitude adjustment knob' while holding the brass eyebolt until it lines up with the 'position bolt'. Secure the 'latitude position bolt'.
