K2000R MAINTENANCE AND CARE
As with the K2000, with minimum of care the K2000R will provide
years of reliable enjoyment. Please follow the following points
to maintain the K2000R at peak performance. To avoid redundancy,
the maintenance tips for the K2000 and K2000R remain the same,
thus this section will only detail those areas that are
graphically different and require a different approach.
Proper installation is essential to the health and welfare of the
K2000R. It should rest on a stable and level flat surface using
the "feet" supplied in the kit and with adequate ventilation above
and below the unit ... OR in a proper rack mount arrangement making
certain to provide the same ventilation space.
Remember, there are no user-serviceable parts in the K2000R.
Under no circumstances should anyone other than a qualified
technician attempt to remove any panels from the unit, except for
battery replacement. Any attempt to open the K2000R risks sever
electrical shock and may void the product warranty.
Cleaning the K2000R
Refer to paragraph 4.1.1 for cleaning details. Ignore any
reference to keyboard because the K2000R is not so equipped. DO
NOT REMOVE ANY PANELS! DO NOT USE STRONG CLEANERS OR SPRAY
ANYTHING ON THE FRONT PANEL OR INTO VENTILATION HOLES!
Floppy Drive Maintenance
Refer to paragraph 4.2.1 for details and to section 3.3 for access
information.
Battery Selection and Replacement
The K2000R uses three AAA batteries (1.5V) to preserve its
internal memory when the power is turned off. The original
batteries should last at least one year before they need
replacing. Replacement is necessary when the LCD says "BATTERY
VOLTAGE IS LOW" during power-up, or when it is noticed the LEDs
flash twice instead of once during power-up. Once these warnings
begin to occur, the batteries should be replaced within a couple
of weeks to ensure continued safety of the RAM entries.
To replace the batteries, simply orient the unit such that the
rear panel is accessible, particularly the lower right corner of
the rear panel.
• Locate the round battery cover and, using a coin, rotate the cover counter-
clockwise 1/4 turn. It will naturally eject itself into the hand because
the batteries are spring loaded.
• Remove the batteries (3) and replace. NOTE: It may be necessary to
slightly tilt the body of the K2000R toward the rear to remove the
remaining two batteries. When replacing the batteries, be certain to
install them with the positive tip toward the rear of the unit.
