3. Setup

3.1 Installazzjoni tal-batterija

The Nitecore EA81 requires 8 AA batteries for operation.

Ħoll l-għatu tad-denb tat-torċa billi ddawwru kontra l-arloġġ.
Insert 8 AA batteries according to the polarity markings (+/-) inside the battery compartment. Ensure correct orientation to prevent damage.
Invita l-għatu tad-denb lura lejn l-arloġġ sakemm ikun issikkat sew.

TWISSIJA IMPORTANTI: DO NOT USE RECHARGEABLE BATTERIES ON THIS LIGHT! Using rechargeable batteries or certain alkaline batteries may lead to leakage and damage to the flashlight. Always use high-quality, non-rechargeable AA batteries and inspect them regularly.

3.2 Kontroll Inizjali

After installing batteries, briefly press the power button to ensure the flashlight turns on. If it does not, check battery orientation and ensure the tail cap is fully tightened.

4. Istruzzjonijiet Operattivi

4.1 Power On/Off

To turn on the flashlight, press the On/Off switch (lower switch) until it clicks.
To turn off the flashlight, press the On/Off switch again until it clicks.

4.2 Livelli ta 'Luminożità

The EA81 features five brightness levels: Ultralow, Low, Mid, High, and Turbo.

With the light on, press the Mode switch (upper switch) repeatedly to cycle through the brightness levels in ascending order: Ultralow → Low → Mid → High → Turbo.
The flashlight will memorize the last used brightness level (except for Turbo and Ultralow) and will turn on in that mode next time.

4.3 Modi ta' Aċċess Dirett

The EA81 provides quick access to the lowest and highest output levels.

Instant Turbo (2150 lumens): With the light turned off, hold the Mode switch for more than one second.
Instant Ultralow (1 lumen): With the light turned off, hold the On/Off switch for more than one second.

4.4 Special Modes (Strobe, SOS, Location Beacon)

The EA81 has three concealed special modes for emergency or signaling purposes.

With the light on, press and hold the Mode switch for more than one second to activate Strobe mode.
Once in Strobe mode, press the Mode switch again to cycle through SOS and Location Beacon modes.
To exit special modes, briefly press the Mode switch. The flashlight will return to the previously used brightness level.

4.5 Advanced Temperature Regulation (ATR)

The EA81 incorporates ATR technology, which dynamically adjusts output performance according to its internal temperature. This prevents overheating and prolongs the lifespan of the flashlight. When the flashlight heats up, the output may automatically decrease to maintain a safe operating temperature.

4.6 Dawl Indikatur tal-Enerġija

The integrated power indicator light, located beneath the switches, displays the remaining battery power.

When the battery level is above 50%, the indicator light will flash once every two seconds.
When the battery level is below 50%, the indicator light will flash rapidly.
When the battery level is critically low, the indicator light will flash very rapidly, indicating that batteries should be replaced soon.

5. Manutenzjoni

5.1 Tindif

Regularly clean the flashlight body with a soft, damp cloth. For the lens, use a lens cleaning cloth and solution to avoid scratches. Keep the threads of the tail cap clean and lubricated with silicone grease to ensure smooth operation and maintain waterproofing.
