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 warn-

ing 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 press-

ing the down arrow (t) (TIME) button, the dive computer will calculate

and show the next deeper no-decompression limits in 3 m [10 ft] incre-

ments 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 calcu-

lates 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 Alti-

tude 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

previous 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 first 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-fly time at the beginning of the dive.
