2. Precautions for safety
2.1. Laser damage
The instrument uses a visible red laser for distance measuring. The laser is emitted from the center of telescope
objective when measuring or laser pointer is turned on.
The instrument's laser plummet uses a visible red laser to indicate the position of the vertical axis. The laser is
emitted from the bottom of the instrument along the center axis during leveling and centering operations.
In accordance with the state of the international standard IEC 60825-1(2014-05), the product is classified as
different Laser class on different working mode.
Working Mode
Laser Class
Distance measuring with reflector prism and tape
Class 1
Distance measuring without reflector
Class 3R
Laser plummet
Class 2
Direct laser beams can cause eye discomfort, temporary blindness and residual images. Prolonged exposure to laser
beams can cause permanent damage to the eyes.
•Do not look directly at the laser beam at any time, and do not use optical equipment such as binoculars
to view the laser beam.
•It is prohibited to direct a laser beam at another person.
•Do not stare at the spot of laser for a long time at close range.
•Avoid direct the laser at any highly reflective object that is not a reflector prism or tape, such as windows,
mirrors, traffic signs, etc.
•Turn off the pointer and plummet laser as much as possible when not working on distance measuring or
centering.

Stonex R20 – User Manual 7
2.2. Glare damage
Looking directly at hard light can cause eye discomfort, temporary blindness and residual images, and prolonged
exposure to direct bright light can cause permanent damage to the eyes.
•Viewing the sun through the instrument's telescope is prohibited at any time.
•Avoid using instruments to aim at objects that are strongly reflecting sunlight, such as mirrors, glass,
water, car surfaces, etc.
•Avoid observing strong lights and other light sources.
2.3. Fire risk
The design and manufacture of the instrument and its accessories follow the relevant standards and directives to
avoid as much as possible the danger of high temperature, fire and other dangerous conditions in normal
operation. However, using the instrument under special conditions, using it irregularly and disassembling it may
lead to localized high temperature, fire or even explosion.
•The use of this instrument in coal mines is prohibited.
•When there are dangerous, flammable or explosive gases or liquids in the vicinity of the workplace, it is
prohibited to operate the instruments.
•Do not use the instrument in a hot environment or near flames.
•Batteries must not be placed in fire or high temperature environments.
•The battery should not be covered by any object during charging to avoid the risk of overheating and
fire.
•The battery must not be disassembled.
•Avoid keys, metal objects connected to the electrodes of the battery, or the electrodes of the charger.
•Avoid the use of unqualified, faulty or damaged sockets when charging, and prohibit any operation that
uses wires directly connected to the plug.
•Avoid contact of the instrument, batteries, chargers, adapters, power cables, etc. with any liquid. Avoid
using, storing, or charging the instrument in a raining, dripping, or wet environment.
•Batteries shall be transported in proper packaging.
•Do not use any batteries, chargers, adapters, power cables, etc. that are not supplied by the Company.
•If any abnormality or damage is found in batteries, chargers, adapters, cables, etc., stop using them
immediately and dispose of them properly.
•Keep batteries, chargers, etc. clean to avoid excessive dust accumulation.
•Do not make any modifications to the instrument, batteries, chargers, adapters, cables, etc.
2.4. Electric shock risk
This instrument is powered by rechargeable batteries. The charger needs to be connected to city power during the
charging process, and any improper handling of electricity may result in electric shock.
•Prohibit operate near high-voltage power transmission and large power facilities.
•Whenever possible, avoid using centering rod near electrified railroads, power lines, etc.
•Outdoor work during thunderstorms is prohibited.
•Do not operate instruments, batteries, chargers, etc. with wet hands.

Stonex R20 – User Manual 8
•Avoid keys, metal objects connected to the electrodes of the battery, or the electrodes of the charger.
•Avoid the use of unqualified, faulty or damaged sockets when charging, and prohibit any operation that
uses wires directly connected to the plug.
•Avoid contact of the instrument, batteries, chargers, adapters, power cables, etc. with any liquid. Avoid
using, storing, or charging the instrument in a raining, dripping, or wet environment.

2.5. EMC
The instrument is designed and manufactured in accordance with the relevant standards for electromagnetic
compatibility, but it may still cause electromagnetic interference that interacts with other electronic equipment
nearby. Instrument and charger in operation may interfere with nearby sensitive electronic equipment and affect
their normal operation. Strong sources of electromagnetic radiation in the nearby environment may also interfere
with the instrument, causing unpredictable measurement errors, abnormal operation and, in particularly serious
cases, even irreversible damage.
•Avoid using instruments in environments of strong electromagnetic interference, such as near large
electrical utilities, high-power radio transmission facilities, wireless communication equipment, big
electric motors, etc.
•If abnormal display, abnormal jumping of measurement data and other abnormalities are detected
during operation, stop operation immediately and turn off the instrument. Continue operation only after
confirming that the surrounding electromagnetic compatible environment is suitable for continued
operation.
2.6. Mechanical injury
Instruments and tripods are heavy objects that may cause damage to people, equipment or other items if
dropped, fallen or broken. Be careful when handling, using, and transporting the instruments, as they are precision
instruments.
•To avoid the risk of injury from collapsing, the tripod should be set up carefully according to the
instruction, and the clamping screws should be tightened after the adjustment of the tripod legs.
•The instrument must be properly fixed on the tripod and checked frequently to avoid injury from falling
or damage to the equipment.
•In all cases, be aware of the possible danger posed by the sharp toe of the tripod legs. Care shall be
taken when setting or handling.
•Dropping and high intensity shaking of the transport case may damage the case and the instrument.
•Do not sit or stand on the transport case, and avoid placing heavy objects on the case.
•Do not use a transport case with broken body, damaged hinges, or latches.
•Avoid strong vibrations, shocks to the instrument, tripod, transport case, etc.

Stonex R20 – User Manual 9
2.7. Other saftety items
•It is not permitted to use the instrument in locations where measurement operations are prohibited by
law or other regulations.

•The use of a qualified tribrach is required for the instrument. Fasten the instrument with its tribrach
correctly.
•When measuring, the instrument and tribrach must be properly and solidly fixed on the top plate of
tripod with the fixing screw. The clamping screws should be tightened after the adjustment of the tripod
legs.
•Avoid vibration of the instrument and tripod during measurement.
•When handling instruments, avoid bumping and dropping as much as possible.
•When lifting the instrument, always grip the handle properly and make sure it is securely attached to the
instrument.
•Do not leave the apparatus in a hot environment for too long, paying particular attention to
environments where the temperature may be too high, such as in a car in hot weather.
•Sudden changes in the temperature of the instrument will affect the measurement accuracy. If the
ambient temperature changes too much, the instrument should be left for a period to adapt to the
ambient temperature before starting measurements.
•Avoid direct sunlight on the instrument during measurement, and it is recommended to use umbrellas or
other shelters.
•Check the battery level to ensure sufficient operating time.
•It is recommended that you do not remove the battery while the instrument is on. Please remove and
install the battery after the instrument is turned off.
•Any obstructions in the path of view between the instrument and the target to be measured during
distance measurement operations may lead to erroneous measurements.
