diving.
Danger
●Before use of this product, obtain a C-card after completing a proper training program at an
internationally recognized diving instruction organization, and be familiar with the proper use of a
diving gear, or use it under the direction of the diving instruction organization. It may cause accident
resulting in injury or death
●Never dive without a buddy. Make sure you keep buddy system. The diving without a buddy is very
dangerous as it may lead to a serious accident.
●When you use it for Nitrox (EANx) diving, you are required to attend and complete a class of the Nitrox
(EANx) diving. Please do not use it for the Nitrox (EANx) diving if you do not take and complete the
lectures.
Reference: EANx: Enriched Air Nitrox (Abbr.: Nitrox)
The mixed gases which raised a ratio of oxygen than usually use compressed air (21% of FO2).
●Please always set the fraction of oxygen (FO2) every diving. It is very dangerous when the fraction of
oxygen (FO2) of the tank and the setting value of this product are not equal.
[Note]: Useful Information to know.

IMPORTANT INFORMATION
Warning
●When you perform scuba diving, please always perform it with good health condition. When you feel
uneasiness in physical condition, avoid unreasonableness and stop the diving.

than the display data indicate. Otherwise it may cause decompression sickness and other diseases
come from diving.
●Do not attempt decompression diving. This product is designed for no-decompression diving. Although
it will do decompression calculations in an emergency if you accidentally enter a decompression dive,
diving under such condition may cause accident resulting in injury or death.
●Do not use this product in a purpose except the recreational diving.
●This product is designed for diving using compressed air (21% of FO2) and Nitrox (EANx) gas (22-
50% of FO2). It cannot be used for other mixed gases.
●Do not y or ascend to high place within 24 hours after diving. There is high possibility that you suffer
from decompression sickness due to the drop in barometric pressure. We recommend that you
should rest for at least 24 hours, or 48 hours if possible, before ying or ascending to altitudes.
●Please follow the display of warning and caution message of this product immediately. Otherwise, it is
much possible that you suffer from decompression sickness.
Danger
