Maintenance and Servicing | iOptron MiniTower Pro instruction

6.8. Set Up Tracking

A user can set up tracking in the main menu by selecting “Set up tracking”. Then the user can select “Sidereal speed”, “Solar speed”, “Lunar speed”, and “User defined speed”. For “User defined speed” this can be adjusted from 91% to 109% of sidereal speed by pressing the ▲or ▼ buttons.

6.9. User Objects

Besides various star lists available in the hand controller --you can add, edit or delete your own user-defined objects. All data you enter is supposedly J2000.0 epoch.

6.10. Auto Guide

This is an advanced function for autoguiding when a guiding scopes and a camera are equipped. The GOTONOVA supports autoguiding through ASCOM protocol, such as PHD Guiding or Guidedog, or an ST-4 guiding camera (an extra ST-4 to HBX adapter is needed). Please follow the guiding software for detailed instructions.

This function is not supported in Alt/Azi mode.

6.11. Park Scope

This procedure only needs to be done if you do not move your telescope mount after you power off the GOTONOVA. Celestial pole pointing error will be stored to flash memory and recalled when you power on again.

6.12. To Park Position

This moves your telescope to park position. When power is turned on--the mount assumes the physical position is the park position. This is its reference point for all other objects.

7.Maintenance and Servicing

7.1. Maintenance

The MiniTower Pro is designed to be maintenance free. Do not overload the mount. Do not drop the mount which will damage the mount or affect the GOTO tracking accuracy permanently. Use a wet cloth to clean the mount and hand controller. Do not use solvent.

If your mount is not to be used for an extended period, dismount the OTAs and counterweight. Remove the batteries from the battery holder if they were installed.

7.2. Troubleshooting

The following suggestions may be helpful for the operation of the MiniTower Pro. More information can be found in our online FAQ section (www.iOptron.com then click on “support”).

1.Error Message “Warning! DEC. (or R.A.) driver motor over current. Please check balance.”

(1)Check if the mount or OTA is blocked by any obstructions.

(2)Try to operate the mount without an OTA.

(3)Check the power supply. This is a common reason for this message and unexpected slew behavior or movement. which include:

• Batteries: Are the batteries fresh? How long have they been used? (frequent slewing and GOTO will deplete battery power very quickly)

• AC or DC adapter: Check the plugs to

the mount and to the power outlet.

• Extension cord: Make sure the cord is in good condition. Power drop along the extension cord has been known to cause this error message. Also check all the plugs and connections.
