Suunto D6I manual Alt. adjustment value Altitude range, How the Altitude value is set

When programming the instrument for the correct altitude, you need to select the correct Altitude Adjustment settings according to Table 5.6, 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 (refer to Sec- tion 10.2.3. Altitude diving).

Table 5.6. 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 5.9.2. 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 recom-
	mended that you acclimatize to the new altitude by waiting at
	least three (3) hours before diving.
