Turning the Calculator On and Off

To turn the calculator on, press and release the
key. "ON" is
printed on the bottom of the
key in blue.
To turn the calculator off, press
Since the calculator has
Continuous Memory, turning it off does not affect any informa-
tion you've stored.
To conserve energy, the calculator turns itself off after 10 min-
utes of inactivity. If you see the low–power indicator
in the
display, replace the batteries with two new CR2032 (or equiva-
lent) batteries as soon as possible. See appendix A of the HP
35s Scientific Calculator User's Guide for instructions.

Adjusting Display Contrast

The display contrast depends on lighting, viewing angle, and
the contrast setting. To increase or decrease the contrast setting,
press and hold the
key while at the same time pressing
Ù or
repeatedly. Each press of these keys very slightly adjusts the
contrast, darker or lighter, respectively.
