Dive Mode Settings - Suunto D4 User Manual

Once in the permanent Error mode, only the Er warning is shown in the center window.
The dive computer will not show times for ascent or stops. However, all the other dis-
plays will function as before to provide information for ascent. You should immediately
ascend to a depth of 3 to 6 m/10 to 20 ft and remain at this depth until air supply limit-
ations require you to surface.
After surfacing, you should not dive for a minimum of 48 hours. During the permanent
Error mode, the Er text will be displayed in the center window and the planning mode
will be disabled.

5.8. DIVE mode settings

Suunto D4 has several user-definable functions, as well as depth and time-related
alarms that you can set according to your personal preferences. The DIVE mode
settings are dependent on the dive submode chosen (AIR, NITROX, FREE), so that,
for example, nitrox settings are only available in the NITROX submode.
The table below shows what dive settings are available in each DIVE submode.
