The relevance of the safety instructions always depends on the degree of difficulty of the dive and its requirements. The same applies to the execution of technical work.These safety instructions can therefore not be considered comprehensive.

• The user must always be provided with the product description.
• The product may only be used for its intended purpose.
• The training and level of knowledge must fully cover the intended use.
• The user's level of training may restrict the intended use.
• If the user does not understand this description or has doubts, he must not use the product.
• These instructions are not a substitute for training.
• Defective, worn or modified products must not be used.
• The contact of normal steel parts with stainless steel parts also leads to rust stains on stainless steel parts.

• Never shine the light directly or indirectly (with or without aids) into the eyes of people or animals.
• Keep the lamp away from children.
• The batteries must always be removed for transportation. If the lamp is well insulated in your luggage, there is a risk of overheating if it switches itself on.
• Overheating may occur if the LED bulb is used in lamps without sufficient cooling equipment.   
• Despite the high reliability of LED lamps, it can happen that an LED fails. This circumstance must be taken into account when designing the redundancy.
• Turn on each lamp once before each dive.
• Batteries are more reliable than rechargeable batteries.
• When new batteries are used, their no-load voltage (= unloaded operation) must be measured with an accuracy of 0.01V. Note this voltage on each battery. Measure the voltage before each demanding dive. If a battery has discharged more than 0.03V, replace the entire set.
• Do not use batteries for demanding dives older than 1 year.
• Buy batteries from suppliers with high throughput to purchase batteries with short battery life.  to get storage time.
• Only use reliable battery types from well-known manufacturers.
• If the lamp will not be used for a long time, remove the batteries, because they can leak.
• Should the lamp actually run full of water during a dive, be very careful when opening, as the lamp may be under high pressure.
