Remove the CW Safety Screw on the end of the CW shaft. Loosen the CW Locking Screw on the
side of the CW (there is a CW pin inside) and slide the CW into the shaft. Tighten the CW Locking Screw to
hold the CW in place. Tighten the CW Safety Screw.
CAUTION: For safety reasons, the CW Safety Screw must be installed and tightened to prevent the
CW from dropping off the end of the CW shaft. This can cause serious personal injury.
STEP 8. Attach and Balance an OTA on the Mount
After attaching an OTA and accessories to the mount, the mount must be balanced to ensure
minimum stress on the mount’s gears and motors. There are no clutch screws on either R.A. or DEC axes.
The balancing is performed using iOptron Electronic Balance technology.
Set the mount at Zero Position first. If it is not, turn the mount on, press the arrow key on the hand
controller to adjust the mount position. Press number key on the hand controller to select appropriate
speed. After the Zero Position is adjusted, turn the power off.
Balance the mount in R.A. and DEC axes
When the mount is rest at Zero Position, turn the mount power on. Press the MENU button, scroll
down to “Balance Test”, and press ENTER. The mount will start to slew and stop at the balance test
position, as shown in Figure 16.
