5.1. Preparing the Device for Operation
•Unbolt a screw and open battery compartment cover at the bottom of the device.
•Insert one 9V battery (sold separately) into the battery compartment observing correct polarity.
•Close up the battery compartment cover, tighten the screw.
After changing the battery, it is recommended to run the CL (CLEAR) mode (refer mode selection procedure).
•Take off lens caps
•Look through the eyepieces (1) (fig. 1).
•Adjust interpupilary distance by turning lever (9) (fig. 2) until two images converge into one
•Make dioptric correction individually for each eye by rotating rubber rings (4) (fig. 2) of each eyepiece
Now your unit is ready for operation as a conventional 7x binocular (passive state).
5.2.Distance Measuring Procedure a. Measuring state
When the Rangefinder is in the passive, low power state, the LCD Display is blank (transparent).
Pressing any of the operating buttons activates the System and the Display. Initially the System always assumes READY mode of operation and word READY appears on the Display.
Pressing Action button (6) (fig. 1) at this point triggers a distance measuring session, and the result will be displayed in numerical form (4) (fig. 3) (if measurement is unsuccessful then four dashes
must be over 20m away.
If the Action button (6) is held (pressed) for more than 3 seconds the System automatically enters SCANNING mode. This feature is not available on all versions.
At this mode the System repetitively performs distance measuring and displaying. The time interval between measurements is approximately 1 second.
The maximum measuring range for most objects will be 1512m. The maximum measured distance will vary greatly depending on the reflectivity of the target, weather conditions and more.
Target reflectivity depends on its color, surface finish, shape etc. Bright colors are more reflective than darks. A polished surface is more reflective than a rough one. Larger targets are easier for distance measuring. Measuring a target faced at 90o (perpendicular to the laser beams path) provides optimal results.
Bad weather conditions (rain, fog, snow, mist) will reduce the maximum measured range.
Bright sunny days will reduce performance as well
While the unit will work through many glass types, measuring through glass will affect the results.
