The A1 Slope is a laser rangefinder with adjustable eyepiece focus, unit selection (yards/meters), and slope mode toggle. The display activates with the Power/Fire button, showing distance and laser status. It has a non-replaceable rechargeable battery (4-hour charge). Accuracy issues may result from incorrect unit settings.
BASIC OPERATION
While looking through the A1 Slope, depress the Power/Fire button once to activate the display. If the display icons and numbers are blurry, rotate the eyepiece in either direction until they are in focus (see “Adjusting the Eyepiece” below).
1. Place the aiming circle (center of the display) over a target at least 5 yards away. Press and hold the Power/Fire Button until the “line of sight” distance displays near the bottom of the display. Crosshairs surrounding the aiming circle indicate that the laser is transmitted.
2. After a range is acquired and displayed, you can release the Power/Fire button. The crosshairs surrounding the aiming circle will disappear once the Power/Fire button is released (i.e., the laser is no longer transmitting).
3. Once activated, the display will remain visible and display the last distance measurement for 10 seconds. Press the Power/Fire button again to range to a new target. The maximum time the laser is transmitted (active) is 5 seconds. To re-fire, press the button down again.
ADJUSTING THE EYEPIECE
The A1 Slope is equipped with an adjustable Fast Focus eyepiece diopter dial (+/- 3.5 diopter adjustment) that allows you to focus the displayed data and icons relative to the viewed image from the monocular optics. Rotate the eyepiece until the display is in focus.
ACTIVE LASER
Crosshairs surrounding the aiming circle indicate that the laser is transmitted. Once a range is acquired, you can release the Power/Fire button. The crosshairs surrounding the circle will disappear once the Power/Fire button is released (i.e., the laser is not transmitting).
