Pressing  again zooms in even farther.
Pressing  zooms out, resulting in a graph whose
time scale spans twice that of the previous view. This dou-
bles the number of displayed samples.
Navigating a Zoomed View
While zoomed in on a graph, only a subset of the total
number of samples are visible. To view samples that were
recorded earlier or later than those in the current view,
press the left and right cursor keys. The availability of ear-
lier or later samples is indicated by the presence of arrows
at either end of the X (time) axis.
12.12 Low Battery Notifica-
tion
The E2 keeps track of how long the E2 battery has
been active, and will display a battery icon at the top
of the E2 screen whenever the battery is reaching the end
of its recommended battery life. If a battery has less than
30% of its battery life left, a yellow battery icon will
appear at the top of the screen. If the battery has less than
10% life left, or if the battery switch is currently disabled,
a red battery icon will appear.
For more information on battery testing and replace-
ment, refer to Section 4.4, Battery Testing and Replace-
ment.
