- Indicação de baixa potência: Se o volume da bateriatage drops below 2.2V, the reticle will quickly triple-flash once per minute, signaling that an imminent battery replacement is recommended.
- Optical Quality: Engineered with premium optical glass and advanced multilayer coatings, the Osight K delivers maximum light transmission, reduced glare, and enhanced durability, while also improving power efficiency.
- Configurações de brilho: Offers 8 daylight and 2 night vision brightness settings for versatility in various lighting conditions.

4. Configuração
4.1 Instalação da bateria
- Locate the side-loading battery compartment on the right side of the optic.
- Using the included adjustment tool or a small flathead screwdriver, carefully unscrew the battery compartment cover.
- If a battery is pre-installed, remove the plastic insulator film to activate it. If installing a new battery (CR1632, not explicitly stated but common for this type of optic), ensure the positive (+) side faces outwards.
- Replace the battery compartment cover and tighten it securely to ensure a waterproof seal. Do not overtighten.

4.2 Mounting the Optic
The Osight K is designed for direct mounting to RMSc/K footprint slides. Refer to the compatibility table in Section 7 for specific firearm models and recommended screws.
- Certifique-se de que a arma de fogo esteja descarregada e em local seguro antes de prosseguir.
- Align the Osight K with the RMSc/K cut on your slide.
- Select the appropriate mounting screws from the included hardware kit. The screws are pre-threaded with thread locker.
- Insert and hand-tighten the screws. Then, use a torque wrench (not included) to tighten the screws to the manufacturer's recommended specifications for your slide. Overtightening can damage the optic or slide.

4.3 Zeroing the Optic
Zeroing is the process of aligning the red dot with the point of impact of your firearm. This should be done at a safe shooting range.
- Mount the optic securely to your firearm.
- Using the included adjustment tool, locate the windage (left/right) and elevation (up/down) adjustment screws, typically found on the side and top of the optic.
- Fire a group of shots at a target from a known distance (e.g., 10-25 yards).
- Observe o ponto de impacto em relação ao seu ponto de mira.
- Adjust the windage and elevation screws as needed. Typically, turning the screw in the direction you want the point of impact to move will adjust the dot accordingly. Consult the 'READ ME' card for specific adjustment increments.
- Repeat firing and adjusting until the point of impact matches your aim point.
5. Operação
5.1 Power On/Off and Motion Activation
The Osight K features motion activation. When the optic detects movement, it will automatically power on. If no motion is detected for approximately 3 minutes, the optic will enter a sleep mode to conserve battery. Any subsequent movement will instantly reactivate the dot.

5.2 Ajuste de brilho
The Osight K offers 10 brightness settings: 8 for daylight conditions and 2 for night vision compatibility.
- To increase brightness, press the '+' button located on the side of the optic.
- To decrease brightness, press the '-' button located on the side of the optic.

5.3 Indicação de Bateria Fraca
Quando a bateria voltage drops below 2.2V, the red dot reticle will flash three times rapidly, once per minute. This serves as a warning to replace the battery soon.
