1. Precautions for safety
1.1. Note
Don’t collimate the sun directly
Avoid insolating the instrument, and don’t collimate the sun directly for protecting eyes and instrument.
Avoid the vibrations on the instrument
When transporting, keep the instrument in the case and try your best to lighten vibrations.
Carry the instrument
When carrying, the instrument handle must be hold tight.
Check the battery power
Before using it, you should check the power whether it is enough.
Battery maintenance
If the instrument is not used for a long time, the battery should be taken out from the instrument and stored in
separate place. Meantime, the battery should be charged every month.
Take out the battery
It is not suggested to take out the battery when the instrument is on, otherwise, the stored data may be lost, so it
is better to replace the battery after having powered off the instrument.
Set up the instrument on the tripod
When using it please insure the connection between tripod and instrument is firm. It is better to work with wooden
tripod for the measurement accuracy.
Assemble the tribrach on the instrument
The setting of tribrach would influence the accuracy. The tribrach should be checked frequently, the screw which
connects the tribrach and alidade must be locked tightly. And the central fixing screw should be tight.
High temperature condition
Don’t put the instrument in high temperature condition for a long time, it is bad for the instrument performance.
Temperature changing sharply

Stonex R25/R25LR Total Station - User Manual 4
The sharp temperature changing on the instrument or prism will shorten the distance measurement range, for
example, after taking the instrument out from a warm car to a cold condition, wait for some time, it can be used
when it adapts the surrounding condition.
The noise from the instrument
While the instrument working, it is normal hearing the noise from instrument motor. This will not affect the
instrument work.
Stored data responsibility
STONEX should not be held liable for the lost data because of wrong operation.

3.2. About battery
3.2.1. Battery power symbol
NOTE:
•The working time of battery will be affected by many factors, such as ambient temperature, recharging
time, recharging and discharging times. On the data safe side, we suggest the users 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 the
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 show the power’s decrease or increase immediately.
•It is suggested to check every battery power before field work.
Measurement is impossible, it is necessary to replace or recharge battery
The battery is lower, it is better to replace or recharge it
Measurement is possible

Stonex R25/R25LR Total Station - User Manual 13
3.2.2. Replace the battery
3.2.3. Recharge the battery
As above figures show, connect the charger and the battery, then plug the charger into the outlet of 100V-240V AC
power supply, recharging will begin.
NOTE:
•For a new (or long time no use) battery, in order to fully extend its capacity, it is absolutely necessary
to carry out 3 to 5 complete charging/discharging cycles, and the charging time must be 10 hours at
least each time.
•The indicator light on the charger will illuminate three separate colors for varies mode conditions:
oSolid Red Light —indicates that the charger is working;
oSolid Green Light —indicates that the charge has finished;
oFlashing Red Light —indicates no battery on charging; poor connection or some problems exist.
•It is recommended to continue charging for 1 or 2 hours after the light turns green.
•Once the red-light flashes constantly after the charger is plugged into the outlet of 100V-240V AC
power supply, please remove the battery and reconnected it after 3 or 5 min.
1) Remove the battery
-Press the button downward as shown left;
-Remove the battery by pulling it toward you.
2) Mount the battery
-Insert the battery to the instrument;
-Press the top of the battery until you hear a Click.

3.3. Setting up the instrument
Set up the tripod first: extend the extension legs to suitable lengths and
tighten the screws on the midsections. 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. Make sure the tripod shoes are
firmly fixed in the ground.
Mount the instrument on the tripod head. Supporting it with one hand,
tighten the centering screw on the bottom of the unit to make sure it is
secured to the tripod.
3.4. Centering and levelling-up
Basic levelling-up with the circular level
Move the foot screws A and B in opposite direction till the circular
bubble is perpendicular to a line shaped with screw A and B. The
direction of rotation in left thumb indicates the movement of the
circular bubble.

Stonex R25/R25LR Total Station - User Manual 15
Move the bubble to the center of the circle by turning screw C.
Accurate levelling-up with the plate level
Loosen the horizontal motion clamp and turn the instrument till the
plate level is parallel to a line shaped with screws A and B. Adjust the
screws A and B to make the bubble in the center of the level.
Turn the instrument approximately 90°. Adjust screw C, till the bubble
in the center of the level.
Repeat above steps until the bubble remains in the center of the plate level while the instrument is rotated to
any position.
Accurate levelling-up with electronic level on screen
It is convenient for R25 series to level-up with electronic level, especially when it is difficult to observe the circular
level and plate level.
Firstly, power on the instrument, press {FUNC} button, and then select “F1(Level/Plummet)”. The electronic level
displays on screen.
Secondly, level it by turning three-foot screws and ensure the bubble is in the plate level. Make sure that the black
spot is in the center.

Stonex R25/R25LR Total Station - User Manual 16
NOTE:
•On this menu you can turn on/off the X/Y compensator by pressing ◄/►keys.
•If the instrument is equipped with laser plummet, opening this menu, the laser plummet adjusting
bar will display. With pressing ▲/▼keys the laser lightness can be adjusted.
Centering with laser plummet
External influences and the surface conditions may lead to the requirement of the adjustment of the laser intensity.
The laser can be adjusted in 25% steps as required. If the instrument is equipped with laser plummet, after activating
electronic level, the laser plummet adjusting bar will display. With pressing ▲/▼keys the laser lightness can be
adjusted.
Press the {FUNC} key, and then click F1 or (1) keys to enter the display shown in the upper figure. With pressing
▲/▼keys you can turn on or off laser plummet and set it as four levels of brightness. Thus, that laser emitting
downwards can be seen.
Loosen the center screw of tripod, and move the base plate on tripod head until the laser spot coincides with ground
mark point. Then tighten the center screw.
Repeat leveling and two steps until the instrument keeps leveling and the laser spot coincides with ground mark
point when rotating alidade of instrument in any direction.
After centering, please turn off laser plummet to save power.

3.5. Assembling and disassembling for three-jaws tribrach
It is convenient to assemble or disassemble the instrument from tribrach by loosen or tighten the tribrach clamp.
Disassemble
Rotate the tribrach clamp anticlockwise until the lever is loosen.
One hand holds up the tribrach, another hand holds the carry handle of the instrument and lift out the instrument
from the tribrach.
Assemble
Put the instrument into the tribrach lightly, let the communication port against in the indentation of the tribrach.
Rotate the tribrach clamp clockwise until the lever is tighten.
NOTE: Fix the tribrach clamp: if the instrument doesn’t need assembly or disassembly from tribrach frequently, it is
necessary to fix the tribrach clamp by fixed screw to avoid the disassembly by accident.
Screw out the fixed screw by driver to fix the clamp.
NOTE: These designs, figures and specifications are subject to change without notice. We shall not be held liable for
damages resulting from errors in this instruction manual.
