Suunto D4 manual

WARNING

NOTE

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 manu- facturer-specified batteries. Recycle or dispose of used batteries properly.

It is not possible to change between AIR, NITROX and FREE DIVE modes before the instrument has counted down the no-fly time.

There is one exception to this: You can change from AIR to NI- TROX 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.
