temperature when using the instrument.
3. The instrument should be loaded in box placed in dry and ventilated place and
prevented from shock, dust and moisture when it is not in use.
4. In order to get good accuracy, you should leave the instrument in the box if the
instrument temperature has large difference between working and storing you
may unpack the box and employ the instrument until the instrument reaches the
temperature at the working field.
5. If the instrument is not used for a long time, the battery should be unloaded and
stored separately and charged once a month to prolong battery life.
6. The instrument should be installed in box when it is transported. Extrusion,
collision and violent vibration need to be carefully avoided during the transport
process. The soft mat May be placed around the box on the long-distance
transportation.
7. It is better to use high quality wooden foot stool to make sure the stability of
measurement and improve its accuracy, when setting up the instrument.
8. Only use absorbent cotton or lens paper to wipe the instrument gently if
exposed optical device need to be cleaned.
9. Use flannelette or hairbrush to clean the instrument after using. Do not electrify

Security Guide
Pay attention to the following safety matters when you use the laser ranging
free of prism.
Warning:
Total station fit out laser level 3R/Ⅲa which is recognized by the loge, which is
above:
the vertical locking screw saying:“3A laser product ”.This product belongs to Class
3R level laser .According to the following standards IEC 60825-1:2001Class 3R/Ⅲa
laser product can reach five times of emission limits of the Class 2/ Ⅱin the
wavelength between 400nm-700nm.
Warning :
Continuous stare into the laser beam is harmful.
Prevention:
Do not stare at laser beam or point to others. The reflected beams is the
effective signal of the instrument. It’s safety to observe by eyepiece.
Warning:
When the laser beam is irradiated reflected by prisms, plane mirrors, surface of
metal and windows, it’s dangerous to look straight into the reflected beams.
Prevention :
Don’t stare at the reflected beams. When the laser is switched on (distance
mode), do not obstruct optical path or stand near the prism. Target at a prism with
total station telescope only.
Warning :
It’s dangerous to use the Class 3R laser device improperly.
Prevention:
To avoid injury, each user must carry safety prevention measures and operate
the instrument within the safety scope according to standard IEC60825-1: 2001).
The following is the explanation of the main part of the standard:
Class 3R level laser products are used outdoors and in construction (surveying with
No-Prism).
A: Only trained and certified persons are allowed to install, adjust and operate the
laser equipment.
B: Set up appropriate laser warning sign within the operating field
C: To prevent anyone from looking into the laser beam use an optical instrument to
observe.
D: In order to prevent laser damage to persons, the laser beams should be blocked at
the end of the working route, and also should be cut off when people work in the
restricted area (harmful distance)where laser beams crossing are harmful.
E: The route of the laser beam must set to be higher or lower than the human eye.

F: Properly store and safe keep the laser products when they it is not used,
unauthenticated personals are not allowed using it.
G: Do not point laser beams at surfaces such as plane mirror, metal surface, window,
especially the surface of plane mirror and concave mirror.
Harmful Distance is the maximum distance from the starting point of the laser
beams to where people are right safe. The built-in harmful distance of the Class 3R/
Ⅲa laser is 1000m(3300ft) and the laser intensity will reduce to that of Class 1
products (which does not harm eyes) if people is out of this range.

2Turn the instrument approximately 90° and adjust screw C until the
bubble in the center of the level;
3Turn around the instrument 90°again. Repeat above steps until the
bubble remains in the center of the plate level even though the
instrument is rotated to any position.
2. Centering by centering tool ( optional or laser )
1) Set up a tripod
Extend a tripod to the appropriate height make sure the legs are spaced at
equal intervals and the head is approximately level .Set the tripod so that the head
is positioned over the surveying point. Brace tripod on the ground and keep one
leg fixed.
2) Set up instrument and spotting
Put instruments on a tripod carefully, and tighten the center connection
screw. Adjust the optical centering tool to make reticule clear (open instrument
and laser centering if it’s a laser centering tool).Handle another two unfixed legs,
and adjust their position through the observation of the optical plummet. Make
the three legs of the tripod fixed on the ground when the optical plummet is
aligned to the station approximately .Adjust three feet screws of total station and
keep the optical centering tool (or laser centering) aiming at the station accurately.

guarantee its capacity under other modes .Because consumption of power in
distance measurement mode is more than that in angle measurement mode ,the
instrument may end ranging sometimes due to insufficient capacity of battery
(when switching between modes).
Notice in charging:
Though overcharging protection is installed in the instrument, please plug off the
battery immediately after finishing charging.
Charging range from 0°~±45℃. Abnormal responds of instrument occurs over
this range.
Rechargeable for300—500 times, it may shorten Service time of the battery
completely.
Charge the battery once a month no matter if it is used to prolong its longevity.
4. Reflecting prism
When measuring distance with prism mode, a reflecting prism must be set
at the target site. You can connect the prism to the base, and then connect the
base onto the tripod .you can also set the prism onto the centering rod. There
are single-prism group and three prism group available on the market, so you
can select them according to your requirements.
5. Loading or unloading the base
Loading
Put the three fixed feet in the corresponding bases, make the instrument in
a triangular base, clockwise lock the button by 180°to lock the base, and then
fix screw with a screwdriver to screw it out at a fixed lock knob.
●Unloading
If necessary, the triangle base can be removed from the instrument
(including the same base of reflection prism base connector) by loosening the
lock knob base fixed screw with a screwdriver, and anticlockwise locking button
about 180°, then separate the instrument from base.
6. Adjust telescope objective and aiming target
Aiming method (reference)
①Rotate the telescope and point it to the bright sky and focus reticule clearly (by
rotating eyepiece in own direction and focusing reticule slowly ).
②Aim at the target with the crosswire in optical sight , and keep an appropriate
distance when aiming ( about 200mm).
③Use telescope focus screw to make target clear.
