1 Before You Start
Before you start, please carefully read this part.
1.1 Precautions for Safe Operation
For the safety of your product and prevention of injury to operators and other persons as
well as prevention of property damage, please read this part carefully before using your
product.
Precautions can be divided into the following types according to the degree of loss or
injury in case of negligence or omission:
Warning: Precautions requiring special attention. Ignoring this indication may
possibly result in death or serious injury to the operator.
Caution: Precautions mainly for informing, such as supplementary instructions and
using limitations. Ignoring this indication may possibly result in personal injury or
property damage.
1.1.1 Warning
This instrument is only for qualified surveyor or professional users who have a good
knowledge of surveying.
Please wear the required protectors (safety shoes, helmet, etc.) when operating.
Only e-Survey authorized distributors can disassemble or rebuild the instrument.
Please do not collimate the sun directly. Otherwise, eye injury or blindness and
objective damage may occur.
Please do not cover the charger when charging. Otherwise, fire may occur.
Please do not use wet battery or charger, defective power cable, socket or plug,
and power cable and battery not specified by e-Survey. Otherwise, fire or electronic
shock may occur.
Please do not put the instrument close to burning gas or liquid and the battery in the
fire or high temperature condition, and do not use the instrument in coal mine.
Otherwise explosion may occur.
Please avoid short circuit of the battery. Otherwise, fire may occur.
Please avoid disturbance of severe electrostatic discharge. Otherwise, this
instrument may have some degradation of performance like switching on/off
automatically and so on.
1.1.2 Caution
Please set up the instrument on the tripod, and make sure the connection between
the tripod and instrument is firm. It is better to work with wooden tripod for the
accuracy of measurement.
Please correctly and carefully assemble the tribrach on the instrument for if it is not
correctly or stably installed, the accuracy may be affected, and frequently check the
tribrach to make sure all screws that connect the tribrach and alidade are tightly
locked, and the central fixing screw is tight.
When transporting, please try your best to lighten libration on the instrument.
When carrying the instrument, please tightly hold the handle.

SHANGHAI ESURVEY GNSS CO., LTD.

The sharp temperature changing on the instrument or prism will shorten the
distance measurement range. Therefore, after taking the instrument out from a
condition in which the temperature is totally different from now, please wait for some
time until the instrument adapts to the surrounding condition.
Please do not take out the battery when the instrument is on, and replace the
battery after powering off the instrument. Otherwise, the stored data may be lost.
Please do not touch the instrument with wet hand. Otherwise, there is danger of
electric shock.
Please do not arbitrarily stand or seat on the carrying case, or turn over it.
Otherwise, the instrument may be damaged.
Please be careful of the tripod tiptoe when setting up or moving it.
Please do not drop the instrument or the carrying case, or use defective belt,
agraffe or hinge. Otherwise, the instrument may be damaged.
Please do not touch liquid leaking from the instrument or battery. Otherwise,
harmful chemicals could cause burn or blisters.
1.2 Exemption from Responsibility
You are expected to follow all operating instructions and regularly check the performance
of this instrument.
The manufacturer assumes no responsibility for any damage and loss of profits caused by
the following conditions:
A faulty or intentional usage or misuse.
Any disasters, such as earthquakes, storms, floods etc.
A change of data, loss of data, an interruption of business etc.
Wrong transport, or actions due to connecting with other products.
Usage not explained in the user guide.
1.3 Safety Standards for Laser
E3L adopts the safe and visible laser on the basis of Specification Standard of radiant
products (FDA CDRH.21CFR Part 1040.10 and 1040.11) and Safety of laser products –
parts 1: Equipment classification, requirements and user’s guide (IEC 60825-1:2001).
According to above standards, E3L is class IIIa/3R laser products. When the prism or
reflective sheet is selected in Config mode as target, the output is equivalent to the safer
class 1.
Warnings for Safety
To avoid permanent eye damage, please pay special attention to the following warnings:
Never point the laser beam at other’s eyes.
Never directly look into the laser beam source.
Never stare at the laser beam.
Never look at the laser beam through a telescope or other optical devices.

2.6 Battery
About the battery, please note the following:
The battery’s working time will be affected by many factors, such as ambient
temperature, recharging time, recharging and discharging times. Therefore, it is
suggested to recharge the battery full or prepare several full batteries before
operation.
The battery symbol only indicates power capability for current measurement mode.
The power consumption in distance measurement mode is more than in angle
mode, if the instrument enters into distance measurement mode from angle mode,
the power maybe auto-off because of lower battery.
The symbol only indicates the supply power but not the instantaneous power
change. And if the measurement mode changes, the symbol will not immediately
show the power’s decrease or increase.
It is suggested to check every battery power before field work.
