Blinking Display
The display blinks when any of several improper operation are
attempted. Depressing any key stops the blinking without other-
wise performing the key function. €LX is the recommended
blink stopper. Figure 1-1 lists these improper operations.

During execution of a stored program, the display continuously
changes and is purposely illegible to indicate that the program is
running. When the program stops, the display is steady.
Multiple Decimal Point Display
The battery provides approximately 3 hours of continuous opera-
tion. By turning off the power when the calculator is not in im-
mediate use, the battery power will be conserved. To conserve
power without losing program or results, leave the calculator
on, key in a[+], and leave it there until ready to resume cal-
culation.
All decimal points light in the display when 2 to 5 minutes of
operation time remain in the battery pack. Even when all decimal
points are turned on, the true decimal position is known because
an entire digit position is allocated to the true decimal position.
Example:
T—True Decimal Position
