Familiarize yourself with the various parts of your GUANIEE 10x42 1042RF Laser Rangefinder Binoculars:

4. Setup
4.1 Battery Installation
Your binoculars require one CR2 (3V) battery. To install:
- Locate the Battery Cover on the underside of the binoculars.
- Unscrew the Battery Cover by turning it counter-clockwise.
- Insert the CR2 battery with the positive (+) terminal facing inwards.
- Replace the Battery Cover and turn clockwise until securely tightened.
4.2 Adjusting Eyecups and Diopter
Proper adjustment ensures a clear and comfortable viewing experience:
- Twist-up Eyecups: Rotate the eyecups up or down to achieve the optimal eye relief. If you wear eyeglasses, keep the eyecups fully down. If you do not wear eyeglasses, twist them up until you see a full field of view without shadows.
- Diopter Adjustment: Look through the binoculars at a distant object. Close your right eye and use the Center Focus wheel to bring the image in your left eye into sharp focus. Then, close your left eye and use the Diopter Focus ring (on the right ocular) to bring the image in your right eye into sharp focus. Once set, use only the Center Focus wheel for general focusing.
4.3 Focusing
After diopter adjustment, use the Center Focus wheel to focus on objects at varying distances.
