•the correct oxygen percentages are adjusted according to the measured oxygen percentages in your cylinders

•the oxygen partial pressure limits are set correctly

For more information on the NITROX mode, refer to Section 6.2. Diving in NITROX mode (DIVEnitrox).

The dive computer is now ready for diving.

5.9.3. Battery power indication

Temperature or internal oxidation of the battery affect the battery voltage. If the instrument is stored for a long period, or used in cold temperatures, the low battery warning may be displayed even though the battery has enough capacity. In these cases, re-enter DIVE mode to receive the battery power indication.

After the battery check, 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 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.

5.9.4. Diving at altitude

The dive computer can be adjusted both for diving at altitude and also to increase the conservatism of the mathematical nitrogen model.

When programming the instrument for the correct altitude, you need to select the correct Altitude Adjustment settings according to Table 5.4, Altitude Adjustment settings. The dive computer will adjust its mathematical model according to the entered altitude setting, giving shorter no-decompression times at higher altitudes (see Table 10.1, No-decompression time limits for various depths (m) and Table 10.2, No-decompression time limits for various depths (ft) in Section 10.2. RGBM).

Table 5.4. Altitude Adjustment settings

Alt. adjustment value	Altitude range
A0	0 - 300 m / 0 - 1000 ft
A1	300 - 1500 m / 1000 - 5000 ft
A2	1500 - 3000 m / 5000 - 10 000 ft

NOTE	Section 5.8.4. Setting the personal/altitude adjustments describes
	how the Altitude value is set.
WARNING	Traveling to a higher elevation can temporarily cause a change in the
	equilibrium of dissolved nitrogen in the body. It is recommended that
	you acclimatize to the new altitude by waiting at least three hours
	before diving.
