Initializing the handbox

This exercise describes how to initialize the handbox. Normally, you will enter
the Time and Date at the beginning of each observing session, but you will only
perform the full Initialization procedure (i.e., entering the Location information and
selecting the model number as well as entering the Time and Date) the first time
you use the handbox or after performing a Reset.
1. Make sure that the DEC + RA Lock (1 and 17, Fig. 1a) are tightened according
to the manual.
2. Make sure that the control is properly connected to your telescope.
3. Set the power supply switch „ON". The display field is activated, followed by a
copyright message for a short time. Subsequently you will hear a short signal
tone. The control now takes a moment to boot up the system.
4. Then you will be prompted to enter the date and time. The date is entered
in the „year-month-day / e.g.: 2013-31-12" format. The time is entered in the
„hour-minute-second / e.g.: 20-15-00" format. Use the arrow buttons for this
purpose and confirm your entry with the ENTER button (2 and 5, Fig. 2).
5. You will now be prompted to enter the summertime (Daylight-Saving arrange-
ment). Select the setting „on", if the telescope is used in the summer time.
Select the setting „off", if the telescope is used outside of the summer time.
6. The next screen queries you about the country and the city of your observing
site. You have two different options for entering.
1. You can select a town in your vicinity, located in the database (select
„Country & City"). The countries are listed in alphabetical order in the
database. Use the „up and down" direction buttons to scroll through the
countries and cities in the list. When the desired city appears in the display,
press the ENTER button.
2. With manual input (select „Custom Site"), you can set your location infor-
mation manually. Enter the name („Name"), the longitude („Lon"), the lati-
tude („Lat") as well as the time zone („Zone") and confirm your entry with
the ENTER button.
Example: Name: Berlin ; Lon: E013° 25` ; Lat: N52° 30` ; Zone: E01
The telescope control now displays this on the main screen and is now ready for
alignment in the night sky.
One Star Alignment
After you have completed the initialization, you can align the mounting with the
hand box. The fastest and simplest way to use the positioning of the control, is
the one-star alignment. The alignment can only take place at night.
1. Bring the telescope in the Polar Home position (Fig. 3b) and close the clamps
on both axes.
2. Press 1 x the ENTER button to access the main menu and select the menu
item „Alignment". Then press the ENTER button.
3. Different alignment methods to choose from now appear. Select „One Star",
and then press the Enter button.
4. Now, a choice of alignment stars is displayed. Use the direction buttons „up"
and „down" to select your desired alignment star and confirm your selection
with the ENTER button. The telescope now moves from the starting position,
traversing into the vicinity of the selected alignment star.
5. It may happen that the star does not appear in the visual field of the telescope
after the positioning. Pick up this star in the visual field with the direction but-
tons and then centre on it. The alignment star is normally clearly visible and
the brightest star in the sky region, which the telescope displays. If you have
adjusted the finder scope, it will generally be the brightest star in the visual
field of the finder. After the star is centred in the visual field of the eyepiece,
press Enter. The successful alignment of the telescope is now confirmed with
a acknowledgment tone.
