PRECAUTIONS REGARDING SAFETY
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.
[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.
[Storage and Operating Environment]
To prevent making short-circuit when removing the battery and charger from
