Bushnell 740100 Instruction Manual

To calibrate your Bushnell 740100 Rangefinder, ensure it is turned on, look through the eyepiece at a known distance, and adjust the focus ring until the image is clear. The rangefinder automatically adjusts for accuracy, so no manual calibration is needed.
If your rangefinder is not accurate, check for dirt or obstructions on the lens and clean it with a microfiber cloth. Ensure the batteries are fresh and the rangefinder is set to the correct mode for your activity.
To change the units, press and hold the mode button until the unit of measure begins to blink, then press the mode button again to switch between yards and meters. Release the button to set your preference.
If your rangefinder is not turning on, check the battery compartment for corrosion or contact issues. Ensure the batteries are installed correctly, observing the polarity. If the issue persists, consult the user manual or contact Bushnell support.
