Suunto None manual Batteries. Recycle or dispose of used batteries properly, Mix accordingly

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.
