ABOUT THE DISPLAY:

AUTOMATIC BRIGHTNESS DISPLAY:
The CRF.1 is equipped with a built-in light sensor that reads ambient light. The internal software adjusts the red brightness intensity based on the measured light reading. This allows for the right amount of red brightness for the surrounding environment.
Note: The brightness display is 100% automatic no need to adjust brightness manually.

MENU & NAVIGATION:

ANGLE MODE:
The CRF.1 provides you the ability to measure and display either Line of Sight (LOS) or Angle Compensated distance (COMP). Angle compensated distance is an automatic calculation using the line of sight distance and factors in the degree of elevation angle.
When in Line of Sight Mode and unit is on: “LOS” indicator will be visible in bottom of display.
When in Angle Compensation Mode and unit is on: “COMP” indicator will be visible in bottom of display.
To change Angle Mode:
With CRF.1 on, press the DISP/MENU button for 3 seconds. To change, press the or button until the desired mode is displayed, then press the FIRE button to accept. Angle Mode selection will be displayed within bottom of display as “LOS” or “COMP”.
DEGREE OF ANGLE:
This indicator will only display angle in Line of Sight mode and displays a range from -70 to + 70 degrees
AIMING RETICLE:
Choose from three reticle options (Crosshair, Bracket, and Square).
To change Reticle:
With CRF.1 on, press the DISP / MENU button for 3 seconds. Continue to press and release DISP / MENU button to navigate to the reticle menu. To change, press the or button until the desired reticle is displayed and then press the FIRE button to accept and exit.
UNIT OF MEASURE:
The CRF.1 provides distance measurements in yards (Y) or meters (M).
To change unit of measure:
With CRF. 1 on, press the DISP / MENU button for 3 seconds. Continue to press and -continued on next page release DISP / MENU button to navigate to the Y/M Menu. To change, press the or button until the desired unit of measure is displayed and then press the FIRE button to accept and exit.
FIELD/ FOREST BUTTONS:
Pressing either button allows you to easily and quickly select for your application and environmental setting.
Field – Press the FLO “Field” button when you want to acquire small, hard to hit targets and ignore larger objects in the background (e.g. target in front of trees). Displayed as FLO. Forest – Press the FOR “Forest” button when you want to acquire distance to objects located behind trees, bushes; or when in rainy or snowy conditions (e.g. target behind cover). Displayed as FOR.
SCAN INDICATOR:
With the laser on, press and hold the FIRE button, scan back and forth to various objects; while doing so, watch for changes in the measurement number displayed as you move the aiming reticle across targeted objects. This is a quick way to get an accurate reading on multiple objects. This will be indicated as SCAN within the display.
DISP BUTTON:
Pushing this button once toggles the Automatic brightness display. This button allows you to change the color of the information displayed from black to red or red to black. We recommend that in low light conditions the red display be used, and in bright, sunny conditions the black display be used.
BATTERY LIFE INDICATOR:
Within the display, the Battery Life Indicator shows how much battery charge is remaining.
The Battery Indicator will display the first time the POWER button is pressed and will also display in the MENU. If the Battery Indicator blinks – battery needs to be replaced and the unit will not be operable.
REPLACING BATTERY:
Open the door latch, insert a CR2 battery with positive end facing outwards. Once installed, reinstall the battery door and re latch. 

RANGEFINDING TIPS:

1. Unlike mankind, not all objects are created equal.
   a. Some objects are more reflective than others.
   b. Larger and more reflective objects are easier to detect.
   c. Objects that are lighter in color are generally easier to acquire than dark objects.

2. Rain, snow and fog are not a laser’s friend.
   a. This type of precipitation hinders ranging performance. In these conditions laser will produce a more accurate reading in Forest mode.
   b. Ranging in cloudy conditions can improve ranging performance; bright sunshine can decrease ranging performance.
   c. Ranging over a reflective body of water can cause inaccurate readings.
   d. Flat and perpendicular surfaces reflect better than curved or angled surfaces.

3. Can’t get a reading (horizontal hash marks instead of distance)?
   a. Press and hold the FIRE button while holding the reticle on the target. Ensure that the FIRE button is not released before a distance is displayed.
   b. Use the SCAN feature and technique. With the laser on, view through the eyepiece and align the aiming reticle onto the object and press and hold the FIRE button and move the laser slowly over the object until distance is displayed.

NOTE:
The CRF.1 is designed to reach highly reflective targets out to 2000 yards. If a reading is not displayed, target may not be within the distance threshold, size, color, or  reflectivity needed to provide an accurate reading.

CARING FOR YOUR RANGEFINDER:

CLEANING:

1. Remove as much dust and dirt as possible from the lenses with a blower or bristled brush.
2. Apply a few drops of lens cleaning solution to a lens tissue or microfiber cleaning cloth. Ensure that the cleaning cloth is free from dirt and grit so as not to scratch the lenses. NEVER use a I-shirt, facial tissue or heavy cotton cloth on your lenses as they can scratch the lenses.
3. Using a circular motion, gently remove oil, fingerprints, and grime from the lens surface, working from the center outward.
4. For cleaning and disinfecting surfaces other than glass, spray a microfiber cloth with Lysol spray and wipe down product or use a disinfectant wipe (e.g. Lysol, Clorox, CaviWipes).

When your CRF.1 is not in use for over 3 months, we recommend removing the battery and storing your CRF.1 in a dry location at room temperature.
