SAFETY GUIDE
Internal EDM (Visible Laser)
Warning:
The total station is equipped with an EDM of a laser grade of 3R/Ⅲa. It is verified by the
following labels.
On the vertical tangent screw sticks an indication label “CLASS III LASER PRODUCT”.
A similar label is sticked on the opposite side.
This product is classified as Class 3R laser product, which accords to the following
standards.
IEC60825-1:2001 “SAFETY OF LASER PRODUCTS”.
Class 3R/Ⅲa laser product: It is harmful to observe laser beam continuously. User
should avoid sighting the laser at the eyes. It can reach 5 times the emitting limit of
Class2/II with a wavelength of 400mm-700mm.
Warning:

STONEX R2
3
Continuously looking straight at the laser beam is harmful.
Prevention:
Do not stare at the laser beam, or point the laser beam to others‟ eyes. Reflected laser
beam is a valid measurement to the instrument.
Warning:
When the laser beam emits on prism, mirror, metal surface, window, etc., it is dangerous
to look straight at the reflex.
Prevention:
Do not stare at the object which reflects the laser beam. When the laser is switched
on (under EDM mode), do not look at it on the optical path or near the prism. It is only
allowed to observe the prism with the telescope of total station.
Warning:
Improper operation on laser instrument of Class 3R will bring dangers.
Prevention:
To avoid to be harmed, each user is required to take safety precautions, and take
everything under control within the distance that would incur dangers (according to
IEC60825-1:2001).
The following shows the explanation related to the key sections of the Standard.
Laser instrument of Class 3R is applicable outdoors and in construction field
(measurement, defining lines, leveling).
a) Only those persons who are trained with related course and authenticated are allowed
to install, adjust, and operate this kind of laser instrument.
b) Stand related warning symbols in the scale of use.
c) Prevent any person to look straight at or use optical instrument to observe the laser
beam.
d) To prevent the harm caused by laser, block the laser beam at the end of the working
route. When the laser beam exceeds the limit area (harmful distance*) and when there are
motivating persons, stopping the laser beam is a must.
e) The optical path of the laser should be set higher or lower than the line of sight.
f) When the laser instrument is not in use, take care of it properly. The person who is not
authenticated is not allowed to use.
g) Prevent the laser beam from irradiating plane mirror, metal surface, window, etc.
especially beware of the surface of plane mirror and concave mirror.
* Harmful distance means the maximum distance between the start point and the point
which the laser is weakened to a degree that doesn‟t harm people.
The internal EDM instrument equipped with a Class 3R/III a Laser has a harmful distance
of 1000m (3300ft). Beyond this distance, the laser intensity is weakened to Class I
(Looking straight at the laser beam causes no harm to the eyes.)

previous one. Pay particular attention to this when switching angle measurement mode to
distance measurement mode, because insufficient battery power might lead to interrupted
operation.
●Before outdoor operation, battery power status should be well checked.
③When the measurement mode is changed, the battery power would not immediately
show the decrease or increase. The battery power indicating system shows the general
status but not the instantaneous change of battery power.
²Battery Recharging Cautions:
☆Battery should be recharged only with the charger SC-21 going with the instrument.
☆Remove the on-board battery from instrument and connect it to battery charger. When
the indicator lamp on the battery charger is orange, the recharging process has begun.
When charging is complete (indicator lamp turns green), disconnect the charger from
its power source.
²Battery Removal Cautions：
Before removing the battery from the instrument, make sure that the power is turned off.
Otherwise, the instrument may be damaged.
²Battery Recharging Cautions：
☆The charger has built-in circuitry for protection from overcharging. However,
do not leave the charger plugged into the power outlet after recharging is
completed.
☆Be sure to recharge the battery at a temperature of 0°～±45°C, recharging may
be abnormal beyond the specified temperature range .
☆When the indicator lamp does not light after connecting the battery and charger,
either the battery or the charger may be damaged. Please connect professionals
for repairing.
²Battery Charging Cautions：
☆Rechargeable battery can be repeatedly recharged 300 to 500 times. Complete
discharge of the battery may shorten its service life.
☆In order to get the maximum service life, be sure to recharge it at least once a
month.
2.4 REFLECTOR PRISMS
When measuring distance, a reflector prism needs to be placed at the target place.
Reflector systems come with single prism and triple prisms, which can be mounted with
tribrach onto a tripod or mounted onto a prism pole. Reflector systems can be
self-configured by users according to job.
Illustrated are some prism systems that match:
