SUUNTO Vyper Air - Manual (Page 8)

WARNING SELECT THE CORRECT ALTITUDE ADJUSTMENT SETTING! When
diving at altitudes greater than 300 m/1,000 ft the Altitude Adjustment
feature must be correctly selected in order for the computer to
calculate the decompression status. The dive computer is not intended
for use at altitudes greater than 3,000 m/10,000 ft. Failure to select
the correct Altitude Adjustment setting, or diving above the maximum
altitude limit will result in erroneous dive and planning data.
WARNING SELECT THE CORRECT PERSONAL ADJUSTMENT SETTING!
Whenever it is believed that factors that tend to increase the possibility
of DCI exist, it is recommended that you use this option to make the
calculations more conservative. Failure to select the correct Personal
Adjustment setting will result in erroneous dive and planning data.
WARNING This device contains a Lithium cell battery. To reduce the risk of fire
or burns, do not disassemble, crush, puncture, short external contacts,
or dispose of in fire or water. Replace only with manufacturer-specified
batteries. Recycle or dispose of used batteries properly.
NOTE It is not possible to change between AIR, NITROX and GAUGE modes
before the instrument has counted down the no-fly time.
There are, however, exceptions to this: You can change from AIR to
NITROX mode, as well as from AIR or NITROX mode to GAUGE
mode even during the no-fly time.
When planning both air and nitrox dives during the same dive series,
you should set the instrument in NITROX mode and modify the gas
mix accordingly.
In GAUGE mode the no-fly time is always 48 hours.
