Frequently Asked Questions - MS-80A Omaha
How do I switch between yards and meters?
Press and hold the MODE button for 3 seconds. The display will switch between yards (Y) and meters (M). The selected unit will be saved even after power-off.
How do I replace the battery?
Open the battery compartment cover, remove the old CR2 3V lithium battery, and insert the new one with correct polarity. Ensure the compartment is sealed tightly to maintain waterproof protection.
What is the scan mode and how do I use it?
Scan mode provides continuous distance measurements while you press and hold the POWER button. It is useful for tracking moving targets or measuring multiple objects quickly.
How should I clean the lenses?
Use the included cleaning cloth to gently wipe the objective and eyepiece lenses. For stubborn dirt, moisten the cloth with a drop of isopropyl alcohol and clean in a circular motion. Avoid using abrasive materials.
Is the rangefinder waterproof?
It is IPX4 splash-proof, meaning it can withstand rain and water splashes. Do not submerge it in water. If it gets wet, dry it thoroughly before storing.
What is the maximum measuring distance?
The device can measure distances from 5 up to 800 meters/yards, with an accuracy of ±1 meter/yard. Performance may vary with target reflectivity and atmospheric conditions.
How do I adjust the diopter (eye focus)?
Rotate the eyepiece until the internal display (reticle and numbers) appears sharp. This adjustment compensates for individual vision differences and should be done once for best results.
Can I use the rangefinder while wearing glasses?
Yes, the eyepiece has a long eye relief of 16 mm, allowing comfortable viewing with eyeglasses. You can also fold the rubber eyecup for easier access.
How does the flag pole lock feature work?
For golfing, the flag pole lock mode prioritizes the flag distance over background objects. When enabled, the device will lock onto the flag and display the distance with a stabilized icon.
What precautions should I take in cold weather?
The device operates within -10°C to 50°C. In very cold conditions, the battery may drain faster. Keep the rangefinder warm inside your jacket when not in use, and use a fresh battery for optimal performance.
