The range appears in the area next to "Dist2". After a
suitable range is obtained, press TEST / ▼ ARROW.
Note that "Distance too short" appears if the range
difference is less than 300 feet.
The difference between the two ranges displays on the
screen as follows:
1120 feet
NOTE: The operator and the two aiming points must
be in a straight line for the distance
measurements to be accurate.
The user can increase or decrease this range using the
unit's arrows. When complete, press ENTER.
The Audio Control Menu, which permits the user to
enable or disable the audio alert prompts during the
stopwatch function, will appear. Use either arrow to make
the selection and press ENTER. The "stopwatch ready"
screen displays.
The stopwatch system operates in the same manner as
the "pre-measured" ENTER method described earlier in this
section.
