polarity of the exposed contact of the battery. Check the polarity of the battery to be installed and insert the battery so that the opposite polarity end goes into the battery compartment. To re-install the battery cover, reverse the steps taken to remove the cover. DO NOT OVERTIGHTEN THE KNURLED SCREW. Secure it with finger tightness only. Verify correct battery installation by turning on the sight and checking that the reticle image appears. If the batteries are left in the sight backwards, they will be drained of their power.

ELECTRONIC FEATURES

The Bushnell® Holosight® XLP controls are push-button switches located at the top of the unit as shown in Figure 1. To ensure proper operation of the push button switches, press the switch firmly. Audible and tactile feedback is provided when properly actuated.

1.ON/ Auto Battery Check

Pressing either the Up or Down push-button switch will turn the sight ON. If the Up arrow is used to turn the sight ON it will be set at an 8 hour shutdown mode. That is, if the unit is not re-adjusted for brightness for a period of 8 hours, it will turn off. If the Down arrow is used to turn the sight ON it will be set at a 4 hour shutdown mode. See step 4 under this section for description of Auto shutdown. The sight will automatically perform a battery check every time it is turned on. If the batteries have less than 20% of life left, the sight will turn on with the reticle image blinking on and off for 5 seconds. If the remaining battery life is more than 20%, the sight will turn on with a steady reticle pattern. The battery condition can be checked any time by turning the sight off and on.

2.OFF

To turn the sight off press both UP and DOWN push-button switches simultaneously. Verify that the unit is off by looking through the display window.

3.Brightness Adjustment

Push-button switches vary the brightness intensity of the holographic reticle image. Pressing and releasing the push-button switch moves the brightness level UP or DOWN one (1) step from the previous setting. Pressing and holding the Up or Down push-button switch will change the brightness level up or down continuously. There are fifteen (15) brightness settings providing a dynamic range of 100,000:1 from the lowest setting to the highest setting. When the sight is turned ON, the brightness intensity level is at Level 10.

4.Auto Shutdown

The Bushnell® Holosight® XLP is equipped with an auto shutdown feature and will automatically shut itself OFF 8 or 4 hours after the last push-button control is used. This is determined by the method used to turn it ON in step 1.

MOUNTING

The Bushnell® Holosight® XLP is equipped with mounting hardware to attach to a Weaver-style rail or to a 12 gauge model 1100, 870 or 1187 Remington® shotgun. To achieve the best results and accuracy, the Bushnell® Holosight® XLP must be mounted properly. For the Weaver-style rail mount, the base must be parallel to the bore to achieve the maximum elevation and windage adjustments.
