Please review the following instructions thoroughly. If you are not comfortable with the procedure, please
consider sending the keypad in to Astro-Physics for service. Your keypad should be UN-plugged for this
Remove the battery
1. Remove the KeYPRo, silicone-rubber keypad protector, following
the instructions in a previous document. the KeYPRo does not
need to be removed completely.
2. lay the keypad face down on your work surface. locate the
six small screws in the corners. undo these screws using a #0
Phillips screwdriver. be careful not to strip the screw heads. the
screws do not need to be removed completely. Just back them
out until you feel that they are no longer engaged.
3. carefully open the keypad, taking care to make sure that the white plastic
spacer-washers on the screws are not lost. these spacers are vital to
maintain separation of components and to protect the case from damage.
lay both halves of the keypad with the wires still connected flat on your
work space.
be extremely careful of the fiber-optic cable bundles throughout this
procedure! they are easily damaged. do not crush or sharply bend
the fibers!
4. unplug the display's ribbon connector as shown. gently work the connec-
tor off of the display header. be very careful not to damage the connector
or the pins of the display header that are on the main circuit board.
note: the connector will be snug. do not pull on connector carelessly. the display header pins may bend.
5. view of display connector unplugged (above right). at this point, the display can be carefully removed from the keypad.
lay the display aside on a soft surface. be very careful not to scratch the glass on the front of the display.
6. unplug the lithium battery connector. note the Real time clock (Rtc) module. this is not the battery!! do not at-
tempt to remove this! (see photo top of following page)
procedure!
