knobs and slide the telescope dovatal plate into the
saddle. Tighten the saddle locking knob.
5.
Balancing the Payload:
After attaching the scope and
accessories, the mount head assembly must be
balanced in both R.A. and DEC axes to ensure
minimum stresses on the mount driving mechanism.
CAUTION: The telescope may swing freely when the
R.A. or DEC during the balancing process. Always
hold on to the mount and/or telescope assembly
before releasing the Axle Locking Knob and/or Gear
Switches to prevent it from swinging, which can
cause personal injury and/or equipment damage.
With the corresponding Gear Switch disengaged,
balance in DEC axis by moving the scope with
accessories back and forth in the mount saddle.
Balance the assembly in R.A. axis by moving CW along
its shaft.
Only balance one axis at a time and start with the
DEC axis first. Double check the mount to make sure
both the RA and DEC axes are balanced.
Return the mount to the Zero Position after
balancing; i.e., the CW Shaft points to ground, and
the telescope tip is at its highest position.

Connecting Cables:
Plug in a 12V DC power supply to
the DC12V POWER socket. Connect the Go2Nova
®
8407 Hand Controller to the HBX port on the mount
side panel. Install Wi‐Fi antenna (right angle one) and
GPS antenna.
Refer to the full User’s Manual on how to use the
cable management system.
