• Using the included screwdriver, remove all four screws from the green front cover. Unscrew in the counter-clockwise direction.
• Remove the green cover from the front of the rangefinder.
• Place the black cover on the front of the rangefinder. There are grooves in the front of the laser rangefinder. Slide the cover into these grooves.
• Replace the 4 screws and secure them into the 4 holes of the front cover by turning them clockwise with the included screwdriver. Do not overtighten. Just tighten the screws until they stop.

Tips for Using Your Rangefinder

• Your laser rangefinder comes defaulted to the Golf Mode. This rangefinder provides the Slope “Play” Distance when in the Golf Mode. In this mode, it will display the Line of Sight (LOS) Value on the top line and the Slope “Play” Distance on the bottom line. Your rangefinder will calculate the adjusted play distance based on the angle of decline or incline to the flag. This feature is based on hitting a golf ball, and should not be used for hunting.

• In Golf Mode, to make it easier to range the flagstick, your rangefinder has Pin Lock technology. When you press the Power (Range) Button down to range the flag, the rangefinder will display the nearest distance value (Golf Flagstick) of a group of targets that are within your field of view. The cross indicator ( ) will flash giving you visual confirmation that you have locked on to the golf flagstlck For optimum results, hold the rangefinder as still as possible on your target for up to 2 seconds or until you see the distance appear on your display.

• For hunting, choose the Hunt Mode. The rangefinder will display the Line of Sight (LOS) distance, Horizontal (Angle Corrected) distance, and the Angle value. For archery or shooting, you can use the horizontal angle-corrected shoot-at distance.
  The horizontal angle corrected distance is only for hunting. For hitting a golf ball, use the golf mode which provides the slope “play” distance.

• Under ideal conditions, your Astra Optix™ Pro A-1 Laser Rangefinder can measure the distance of reflective objects out to 800 yds. It can also measure a tree out to 500 yds., a deer out to 250 yds., and the flag out to 250 yards. The Pin Lock feature works up to a distance of 250 yards. The type of target you are ranging strongly impacts the maximum ranging distance.

• Shiny reflective objects such as metal buildings will range much better than less-reflective objects such as trees, animal fur, bushes or grass. Objects that are more dense, such as trees or rock, will range better than bushes or grass. Bright-colored objects normally range better than dark-colored objects. Rain, fog, snow, bright sunny days and dusty days will reduce the overall ranging performance. Cloudy days without fog, snow, rain or dust blowing in the air provide the best ranging conditions. Targets that have a flat surface 90° to the laser emitting from the laser rangefinder range better than targets that have a curved surface, or are positioned at an angle in relation to the emitted laser.

• The Low Battery symbol will flash when the battery life is lower than 25%. We recommend that you change the battery as soon as possible. If at any time, your rangefinder freezes or is not responsive after turning it on, reset the rangefinder by removing the battery. Wait 10 seconds and then replace the battery. This will usually fix the issue.
