Table 3.1. Battery Power Indicator
After activation the Low Battery Warning is indicated by the battery symbol.
If the battery symbol is displayed in the surface mode or if the display is faded
or weak, the
IQ-400
should not be used (Fig. 3.4). It indicates that the battery
is too low to operate the
IQ-400
. If the low battery symbol appears during a
dive, you should abort the dive and begin ascent to the surface.
3.2.2 Dive Planning
It is possible at any time on the surface to enter the DIVE PLANNING mode,
simply by touching the
PLAN and
MODE/
PLAN contacts. The display
will rapidly cycle through the no-decompression limits for various depths from
9 m [30 ft] to 45 m [150 ft] in 3 m [10 ft] increments (Fig. 3.5). It takes about
45 seconds to run through the complete cycle, after which the
IQ-400
will

Temperature affects the battery voltage. If the

is stored
at temperatures below freezing point, the low battery warning
may be displayed even though the battery has enough capacity
in warmer conditions. Make sure that the low battery warning
disappears before diving.
