This document contains useful information about your NexStar 4 telescope that may not have
been included in your instruction manual at the time of printing. Listed below is information
regarding the utility features described under the hand control section of the manual. Please refer
to this addendum when using your NexStar 4 hand control.
Demo and Approach Length
-
These features are only used at the factory as diagnostic tools for
quality control purposes and although they may appear on the hand control display they can not
be accessed by the user.
Light Control
– This feature allows some NexStar models to turn off both the red key pad light
and LCD display for daytime use and to help preserve your night vision. This feature is not
activated on the NexStar 4 model.
Model Select –
The first time the NexStar is powered on, the hand control display allows you to
select your NexStar from a list of different models. If for some reason the incorrect model was
selected, the
Model Select
utility feature allows you to reset the hand control to its factory default
settings.
The
Model Select
feature has a
Custom
option that allows you to enter the exact encoder-gear
ratio for your individual NexStar model. For best possible pointing accuracy, this numeric gear
ratio should be entered into the hand control should you ever need to re-select the telescope
model. To enter the custom encoder-gear ratio for your NexStar model, follow the steps below:
1. When the hand control is turned-on, the display will read NexStar Ready, press the UNDO
button to by-pass the AutoAlign procedure.
2. Press the MENU button and use the Up and Down scroll keys until
Model Select
is displayed
on the screen, and press ENTER.
3. Use the Up and Down scroll keys to select
Custom
and press ENTER.
4. The display will read Azm = ??????? . For the NexStar 4 model, enter the number 1059334
and press ENTER. Now enter the same number for altitude as you did for azimuth, Alt =
1059334 and press ENTER.
5. The hand control will now say Recycle Power. Re-start the power to the telescope to save the
changes.
The telescope will now recognize your NexStar model as long as the custom setting is not
changed.
