5.4. Settings
5.4.1. Set Time and Site
Refer to STEP 10 in Section 3.2.
5.4.2. Set Beep
The Hand Controller allows a user to turn off the beep partially, or even go to a silent mode. To
change this setting press MENU => “Settings” => “Set Beep”,
Select one of three available modes:
"Always On” – a beep will be heard on each button operation or mount movement;
“On but Keyboard” – a beep will be heard only when the mount is slewing to the object or there is a
warning message;
“Always Off” – all sounds will be turned off, including the SUN warning message.
5.4.3. Set Display
Press MENU => “Settings” => “Set Display,”
Use the arrow keys to adjust LCD display contrast (LCD contrast), LCD backlight intensity (LCD
light), and keypad’s backlight intensity (Key light).
5.4.4. Set Maximum Slew Rate
You can change the maximum GOTO speed from default MAX to 512X or 256X. This will prevent
the motor skipping steps when an OTA with a large torque is loaded, such as a large diameter OTA or an
OTA with a long tube. It will also help mount performance at lower temperature.
5.4.5. Set Guiding Rate
This is an advanced function for autoguiding when a guiding camera is utilized either via a Guide
Port or using the ASCOM protocol. Before autoguiding, align the polar axis carefully. Select an appropriate
guiding speed. The latest firmware allow you to set the R.A. and DEC guiding speed differently. The R.A.
guiding speed can be set between ±0.01X to ±0.90X sidereal rate. The DEC guiding speed can be set
between ±0.10X to ±0.99X sidereal rate. Follow the instructions of your autoguiding software for detailed
guiding operation.
