5.5.2. Set Key Beep

Turn the key beep on/off.

5.5.3. Set Azi Work Mode

This function will set the mount azimuth mode while performing GOTO. There are two modes for selection:

AZI +/- 200 degree

AZI free running mode

The “AZI +/- 200 degree” will rotate the mount between -200º and +200º in azimuth direction to avoid AC/DC power line wrapping. However, the mount may take a longer path to slew to an object. The “AZI free running mode” will take a shortest path while rotating along the azimuth direction, which is best for battery operation. The default setting is “AZI +/- 200 degree” mode.

5.6. Align

This function is used for align the telescope. Before star alignment, please make sure the mount is well leveled. In addition to “Solarsys Align,” the system also provides “One Star Align” and “Two Star Align”. Either one can be selected for telescope alignment.

5.6.1. Solarsys Align

Press “MENU”, scroll down the menu and select “Align”. Press ENTER and select “Solarsys Align”. Select any one of the listed solar system object as your alignment target, such as Moon. Press ENTER. If the Moon is above the horizon, the telescope will auto slew to it. If the Moon is not in the center of you eyepiece, use ◄ ► ▲ or ▼ key to center the object in your eyepiece. Press SPEED button to change the slew speed if needed. Then press ENTER to complete the alignment.

5.6.2. One Star Align

From the main menu, select “Align”. Select “One Star Align” and press ENTER. A list of bright align stars that are above the horizon is computed based on your local time and

location. These stars are listed alphabetically. Use ▲ or ▼ button to select a star and press ENTER. The mount will slew to it automatically. Use ◄ ► ▲ or ▼ key to center the object in your eyepiece. Press SPEED button to change the slew speed if needed. Then press ENTER to complete the alignment. Or press the BACK key to cancel the process.

If you have a very good initial setup, one star alignment should be sufficient for good GOTO accuracy. To increase the accuracy you may choose to do two star alignment.

5.5.4. Reset All

Reset all settings to factory default data.

5.6.3. Two Star Alignment

Two star alignment will increase the GOTO accuracy of the mount. It is suggested to do two star alignment after one star alignment.
