• The screen will display “Set Alt Limits:” in the top row, and “Upper=+XXX. X
o
” at the bot-
tom row. Use the Left/Right keys to move the cursor and use the numeric keys to ll the
upper limits. The leading sign can be changed with the scroll keys. Press the ENTER
key to end the input and proceed.
• The screen will display “Lower=+XXX. X
o
” at the bottom row, ll in the data in a similar
way.
Some Sky-Watcher’s mounts are equipped with auxiliary encoders on their primary axes to
support manually rotating the axes without worrying about losing the mount’s alignment sta-
tus. Users may turn off the auxiliary encoder to obtain the best pointing accuracy. The auxiliary
encoder can be turned on again at any time for manually moving the mount.
1. Access the menu “SETUP\Aux. Encoder” and press the ENTER key.
2. Use the scroll keys to select between “Enable” or “Disable” and press the ENTER key.
Note: After re-enabling the auxiliary encoders, it is recommended to use the direction keys to
move both axes for a little bit before asking the hand controller to locate an object.
For an equatorial mount with an autoguider port, the SynScan hand controller can change the
guiding speed of the port.
1. Access the menu “SETUP \ Auto Guide Speed>” and press the ENTER key.
2. Use the scroll keys to choose one of the following guiding speeds list: 0.125X, 0.25X,
0.5X, 0.75X, 1X, and then press the ENTER key.
The following are the steps to set the altitude slewing limits:
1. Access the menu “SETUP\Elev. Limits”, and press the ENTER key.
2. Use the scroll keys to choose options “Enable” or “Disable”, and then press the ENTER key
to conrm.
3. If “Disable” is chosen, the SynScan hand controller will turn off the altitude limit.
4. If “Enable” is chosen, the SynScan hand controller will turn on the altitude limit, and users
can input the upper and lower limits as the following:
• When a user uses the Up or Down direction keys to slew the altitude axis to exceed the alti-
tude limits, the SynScan hand controller will automatically stop the altitude axis and display
“Over slew limit. Slewing stop!”. User has to press any key and the SynScan controller will
bring the altitude axis back.
