1. Main Components

1. Push button (on/off switch)
2. Clip holder
3. PX2 housing
4. O-ring (seal)
5. 2 × Alkaline LR03 / AAA batteries, 1.5 V each
6. Lamp head

---

2. Battery Replacement

• Unscrew the lamp head from the housing.
• Remove empty batteries.
• Insert 2 × 1.5 V AAA alkaline batteries in series, observing correct polarity.
• Screw the lamp head back tightly.
• To prevent accidental switching on, unscrew the head by approx. two turns.

Permitted batteries (certified ATEX / IECEx):

• Varta Longlife Extra 1.5 V AAA LR3
• Varta High Energy 1.5 V AAA LR3
• Energizer Ultra 1.5 V AAA LR3
• Duracell Plus Power 1.5 V AAA LR3
• Energizer Industrial 1.5 V AAA LR3
• Varta Industrial Pro 1.5 V AAA LR3
• Daimon 1.5 V AAA LR3

3. Battery Warnings

• Do not use damaged, leaking or corroded batteries.
• Never mix different types, brands, or ages of batteries.
• Risk of leakage of corrosive liquids or gases.
• Remove the batteries if the lamp will not be used for a long time.

Technical Note: Why batteries from different manufacturers must not be mixed

Even if all batteries are labeled “AAA 1.5 V,” they are not identical:

• Chemical composition: each brand uses different electrolytes and materials, which change electrical behavior.
• Internal resistance and capacity: small variations mean one cell may discharge faster.
• Voltage balance: weaker cells may be forced into reverse polarity by stronger ones, causing leaks or rupture.
• Heat generation: mismatched batteries can overheat, which is especially dangerous in ATEX environments.
• Certification validity: ATEX/IECEx safety approval applies only to specified battery types. Mixing breaks compliance.

⚠️ Mixing batteries from different brands or ages leads to uneven discharge, overheating, leakage, polarity reversal, and loss of safety certification.

4. Cleaning

• Danger of electrostatic charging of the plastic parts of the lamp.
• Clean the glass and housing only with cold or lukewarm (≈25–40 °C) water.
• If necessary, add a mild detergent (gentle, non-abrasive soap).
• Use a soft, lint-free cloth (that does not shed fibers) or a viscose sponge.

---

5. O-Ring

• Check the O-ring before every use.
• O-ring must always be clean.
• Replace the O-ring if damaged.
• Do not use any tools for replacement.

---

6. Safety Notes

• Do not open the lamp in explosive atmospheres.
• Maximum ambient temperature range: –20 °C to +40 °C.
• Protect the lamp from long-term direct sunlight.
• Only use original spare parts supplied by the manufacturer.
• The product complies with Directive ATEX 2014/34/EU.

Optical safety warning (EN 62471):

• Risk Group RG-1.
• Do not stare at the LED source for a long period. May be harmful to eyes.

7. Disposal and Recycling

Batteries, rechargeable batteries and electrical devices must not be disposed of with household waste.
They may contain hazardous substances such as:

• Cd (Cadmium)
• Hg (Mercury)
• Pb (Lead)

Therefore, they must be taken to designated collection points or returned to authorized dealers.
Compliance with this regulation is mandatory and contributes significantly to environmental protection.
