Activate the Arrow Keys
This procedure describes how to activate
Starfinder's Arrow keys:
1. After Starfinder's cord is plugged in and the
batteries are installed, a copyright message
lights on the Starfinder LCD display (1, Fig.
13).
2. A message warning not to look at the Sun
scrolls across the display. Press the key
prompted by Starfinder to acknowledge that
the Sun warning has been read and
understood.
3. Press the ENTER (2, Fig. 13) key repeatedly
until "Country/State" appears on the display.
(Ignore the prompts requesting Date and
Time – these functions will be explained in
Lesson 7, but are not necessary for the
current lesson.)
4. Use the Scroll keys (6 and 7, Fig. 13) to cycle through the database of countries,
states, and provinces. Press ENTER when the correct location displays.
5. Starfinder then prompts you to enter the nearest city (listed alphabetically) to the
observing site. Use the Scroll keys to cycle through the database of cities. Press
ENTER when the correct city appears on screen. The display then reads "Align:
One Star." You now can use Starfinder's Arrow keys to move the telescope to
observe.
NOTE: If you go past the "Align: One Star" (or any other menu display you
wish to select), press MODE to return to the previous display(s).
6. Press the Arrow keys (5, Fig. 13) to slew (move) the telescope up, down, right, or
left. You can slew (move) the telescope at different speeds.
Slew Speeds
Starfinder has seven slew (move) speeds. Each speed has been calculated to accom-
plish specific functions. Pressing the Speed/? key (8, Fig. 13) briefly changes the slew
speed, which is shown briefly on Starfinder’s display as the key is pressed. Each press
decreases the slew speed down one level and then cycles back to the fastest speed.
NOTE: Pressing the Speed/? key briefly changes the slew speed. Holding
down the Speed/? key longer (one to two seconds) accesses the Help
function.
The seven available speeds are:
Speed 1 Max = 240 x sidereal (60 arc-min/sec or 1°/sec)
Speed 2 0.5° = 120 x sidereal (30 arc-min/sec or 0.5°/sec)
Speed 3 64X = 64 x sidereal (16 arc-min/sec or 0.27°/sec)
Speed 4 32X = 32 x sidereal (8 arc-min/sec or 0.13°/sec)
Speed 5 16X = 16 x sidereal (4 arc-min/sec or 0.067°/sec)
Speed 6 8X = 8 x sidereal (2 arc-min/sec or 0.033°/sec)
Speed 7 2X = 2 x sidereal (0.5 arc-min/sec or 0.008°/sec)

NOTE:
Press and hold the
Up Arrow key to
speed up the scroll
speed of the display
or press and hold the
Down Arrow key to
slow down the scroll
speed. When the
display is scrolling at
a speed that is
comfortable for
reading, release the
key.
NOTE: Starfinder
only prompts you to
enter Country (or
State) and City as
described in steps 3,
4, and 5, the first time
it is activated. These
prompts do not
appear again, unless
you reset Starfinder
(see "RESET," page
32).
However, if you need
to enter this
information (e.g., you
change your
geographic location),
you need not perform
a Reset, which
erases user entered
data, such as
Landmarks and User
Objects. You can
change the location
information by using
the Site option of the
Setup menu. See
"SITE," page 32, for
detailed information.
