performance test (water temperature: 4°C) specified by EN250.
When using these regulators in cold water at temperatures of 10°C or below, be sure
to observe the following notices.
General Caution Items
* Before you use the regulator, be sure to receive specialized instruction on cold
water diving from a diving instruction authority so that you learn the necessary skills
and knowledge.
* Be sure to receive orientation for the diving environment.
* Be sure to obey the instructions of your instructors and guides.
Equipment Handling Caution Items
The conditions for freezing up of the regulator change in accordance with the
breathing conditions of its user (breathing volume, breathing speed, number of
breaths) and the environment conditions before and during use.
* Do not take shallow, fast breaths. It makes freezing occur more easily.
* To avoid free flow condition due to freezing NEVER push the purge button while
the regulator is outside of the water.
* Store the regulator at room temperature. When diving, store your regulator in its
bag to keep it warm until just before use.
* When waiting between dives, always keep your regulator warm. Do not leave it out
in a cold environment.
* Your regulator may freeze depending on the conditions. If your regulator freezes, it
may free flow. If it does, use breathing technique for free flow conditions.
* When diving in water temperatures of 10°C or below, always swim at a safe depth
from which you can perform an emergency swimming ascent.
