98 Appendix C: Battery, Warranty and Service Information

Installing New Batteries

The contents of the calculator's Continuous Memory are preserved for a short
time while the batteries are out of the calculator (provided that you turn off the
calculator before removing the batteries). This allows you ample time to replace
the batteries without losing data or programs. If the batteries are left out of the
calculator for an extended period, the contents of Continuous Memory may be
lost.
To install new batteries, use the following procedure
1. Be sure that the calculator is off.
2. Holding the calculator as shown, press
outward on the battery compartment door
until it opens slightly.
3. Grasp the outer edge of the battery
compartment door, then tilt it up and
out of the calculator.
In the next two steps, be careful not to press any keys while
batteries are out of the calculator. If you do so, the contents of
Continuous Memory may be lost and keyboard control may be
lost {that is, no response to keystrokes).
