PRECAUTIONS REGARDING SAFETY
• There is a possibility that the instrument cannot calculate correctly when receiving
reflected laser beam from forth and back directions in case of measuring the target on
the road.
• There is a possibility that synthesized values are calculated and the distance may
become longer or shorter than the actual one when the operator measure the target
of slope or sphere or rugged shape.
• There is a possibility that the instrument cannot calculate correctly by collecting the
reflected laser beam from a man or a car that comes and goes in front of the target.
• When using reflector sheet, set the reflector sheet to have its surface be approx.
vertical to the aiming line. If it is positioned not to be approx. right angle, there is a
possibility that correct distance measurement may be impossible by dispersion or
reduction of laser beam.
In the following environments, the distance might not be able to be measured.
There is a reflection things (mirror, stainless board and white wall, etc.) in the direction
of the target and under too strong sun light.
[Battery & charger]
• Never use any battery charger other than the BC03 battery charger as this may
result in damage to the instrument.
• If water should happen to splash on the instrument or the battery, wipe it off
immediately and allow it to dry in a dry location. Do not put the instrument in the
case until it is completely dry as this may result in damage to the instrument.
• Turn off the power when removing the battery from the instrument as removing
the battery while the power is still on may result in damage to the instrument.
• The battery mark displayed on the instrument is only an estimate of remaining
battery power and is not completely accurate. Replace the battery quickly when it is
about to run down as the time a battery lasts on one charge differs depending on
conditions of ambient temperature, and the measurement mode of the instrument.
• Confirm the battery level remaining before operating.
[Auto focus]
The Auto focus mechanism is very precise but will not function under every condition.
Focusing depends on brightness, contrast, the shape and size of the target.
In such a case, press the AF button and focus on the target by operating the Power focus
key or the AF ring.
[LD POINT, laser pointer]
When you make a correct direction using the “LD POINT”,aim the laser beam at the wall and
mark the center and then confirm the discrepancy between the reticle center and the
marked point beforehand.
