If the battery symbol is displayed in the Surface mode or if the display is
faded or weak, the battery may be too low to operate the dive computer
and battery replacement is recommended.
NOTE! For safety reasons the backlight cannot be activated when the
low battery warning is indicated by the battery symbol.
3.1.2.2. Wireless Transmitter Battery Indicator
The pressure transmitter sends out a lowbat (LOBT) warning when its
battery voltage is getting low. This is shown intermittently instead of the
pressure reading (see chapter 2.4.3, Fig 2.6). When you get this warning
the pressure transmitter battery needs to be replaced.
3.1.3. Dive Planning [PLAN]
To enter Planning Mode, press the PLAN button at any time during Sur-
face Mode. After showing the text “PLAN” (Fig. 3.6.), the display will show
the no-decompression limit for the depth of 9 m [30 ft]. By pressing the
down arrow (t) (TIME) button, the dive computer will calculate and show
the next deeper no-decompression limits in 3 m [10 ft] increments ending
at 45 m [150 ft]. By pressing the up arrow (s) (PLAN) button, the next
shallower depth will be shown again.
The Planning Mode is canceled by pressing the SMART (QUIT) button.
NOTE! The Planning mode is disabled in Gauge mode and in Error mode
(see section 3.9. ”Error Conditions”). The planning mode calculates no
dec times for MIX1 only. If additional mixes are enabled in the Nitrox
mode they do not affect the calculations in PLAN mode.
Higher Altitude and conservative Personal Adjustment Modes will shorten
the no-decompression time limits. These limits at different Altitude and
Personal Adjustment Mode selections are shown in Table 6.1 and 6.2 in
section 6.1. ”Operating Principles”.
The Planning mode also accounts for the following information from pre-
vious dives:
• any calculated residual nitrogen
• all dive history for the past four days
• oxygen toxicity (Nitrox mode)
The no-decompression times given for different depths will therefore be
shorter than before your fi rst “fresh” dive.
DIVE NUMBERING SHOWN DURING DIVE PLANNING
Dives belong to the same repetitive dive series, if the instrument was still
counting down the no-fl y time at the beginning of the dive.
