 IMPORTANT NOTICE! Never use a telescope or spotting scope to look at the Sun! Observing the Sun, even for the shortest fraction of a second, will cause irreversible damage to your eye as well as physical damage to the telescope or spotting scope itself. |

A. Liquid Crystal Display
The large Liquid Crystal Display (LCD) has two rows of 16 characters for
displaying Magellan function menus, telescope position and object information.
The LCD has red LED's to back light the display and can be adjusted to 16
levels of brightness.

B. Keys
[ toc ]
1. Enter
Pressing and releasing the ENTER key activates the menu function indicated
by the LCD arrow positioned to the left of the menu item. Menu items followed
by three dots (i.e. HELP...) mark expanding menus.
Several menu items require information to be edited. Holding the ENTER key
down for a moment will cause a blinking cursor to appear at the edit point.
Each press of the ENTER key will move the cursor one character to the right
until the last character is reached. Once the last character of the field
is reached, pressing ENTER again will end editing if the field is properly
formatted. Otherwise, the cursor repositions itself at the beginning of
the field to allow for corrections.

2. Mode
Pressing the MODE key cycles the display through the four operating modes.
During editing, pressing MODE will terminate an edit and restore the original
value.

3. Prev and Next
Pressing the PREV key moves the display LCD arrow up the list of menu items,
while pressing the NEXT key moves the display LCD arrow down the list of
menu items.
During editing, pressing the PREV key will cause the value behind the flashing
cursor to increment by one and pressing the NEXT key cause the value to
decrement by one.
In the BRIGHTNESS mode, these keys adjust the intensity of the LCD backlighting.

C. Battery
Magellan requires one user supplied 9 volt battery to operate the handbox
and encoder systems. Magellan will operate properly with any battery or
voltage adapter which supplies a proper polarity DC voltage between 5 and
22 volts.

D. Communication Ports
Communication ports are found on the left side of the handbox case. These ports
are designed to accept cables using the standard high reliability telephone
technology plugs. A positive snap action design prevents the cable from
disconnecting during usage.

1. Encoder Port
The encoder port accepts an 8-pin plug from the telescope encoder system.
Installation instructions show the user how to attach these encoders and
cables prior to operation.

2. RS-232 Port
The RS-232 port is used to connect a personal computer to the Magellan System
for added features. Magellan communicates telescope position information
via this interface to software like Epoch 2000 which can display star maps
of the telescope field of view and perform other helpful functions.
