1. Precautions for Safety
1.1 Note
◆Don’t collimate the sun directly
Avoid to insolate the instrument, and don’t collimate the sun directly for protecting eyes
and instrument.
◆Avoiding the librations on the instrument
When transporting, keep the instrument in the case and try your best to lighten librations.
◆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 Maintainence
If the instrument is not in using for a long time, the battery should be taken out from the
instrument and store in seperate 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 power 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 check
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
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
When the instrument working, it is normal if you hear the noise from instrument motor, it
will not affect the instrument work.

2
◆Stored data responsibility
FOIF should not be held liable for the lost data because of wrong operation.

to the safer class 1. Follow the safety instructions on the labels to ensure safe
use.
CAUTION: CLASS 3R LASER RADIATION WHEN OPEN
AVOID DIRECT EYE EXPOSURE.
CAUTION: CLASS 2 LASER RADIATION WHEN OPEN
DO NOT STARE INTO THE BEAM
！CAUTION

●Never look directly into the laser beam source, it could cause permanent eye
damage.
●Never stare at the laser beam, it could cause permanent eye damage.
●Never look at the laser beam through a telescope or other optical devices, it
could cause permanent eye damage.

2. Preparation before Measurement
2.1 About Battery
2.1.1 Battery Power Symbol
NOTE:
◆The working time of battery will be effected 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 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 show the
power’s decrease or increase immediately.
◆It is suggested to check every battery power before field work.

2.1.2 Replace the Battery
1) Remove the battery
①Press the button downward as shown left
②Remove the battery by pulling it toward you
2) Mount the battery
①Insert the battery to the instrument
②Press the top of the battery until you hear a
Click.
2.1.3 Recharge the Battery
As above figures show, connect the charger and the battery, then plug the charger
into the outlet of 110V-220V 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:
Solid Red Light—indicates that the charger is working;
Solid Green Light— indicates that the charge has finished;
Flashing 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 turn
green.
◆Once the red light flashes constantly after the charger is plugged into the
outlet of 110V-220V AC power supply, please remove the battery and
reconnected it after 3 or 5 min.

2.2 Setting Up the Instrument
Mount the battery in the instrument before performing this operation because the
instrument will tilt slightly if the battery is mounted after leveling.
I. 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.
II. 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.
2.3 Centering and Levelling-Up
1. Position tripod legs so that the plummet is aimed to the ground mark point.
Turn the focusing ring of the optical plummet to focus.
2. Turn three footscrews of the tribrach till the center of reticle exactly coincides
with the surveying point in any position.
3. Move the tripod legs to centre the circular level. The instrument is now
roughly leveled-up.
4. Center the bubble in the circular 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.
5. Center the surveying point again
Loosen the centering screw slightly. Looking through the optical plummet
eyepiece, slide the instrument over the tripod head until the surveying point is
exactly centered in the reticle. Re-tighten the centering screw securely.
6. Check again to make sure the bubble in the plate level is centered.
If not, repeat procedure 4.
2.4 Accurate Levelling-Up with Electronic Level on screen
It is convenient for 670/680 series to level-up with electronic level, especially
when it is difficult to observe the circular level and plate level.
1. Power on the instrument and enter into
measurement mode, press F1: [TILT] at P3
or press key {BS} directly, and the electric
level displays on screen.
2. Level it by turning three foot screws, see
above operation “3. Center the bubble in the
plate level”. Be sure the ● is always in the
center.
Note: 1. On this menu you can turn on/off the X/Y compensator by pressing ▲
or ▼ key.
2. If the instrument is equipped with laser plummet, after opening this menu, the
laser plummet adjusting bar will display. With pressing or key the laser
lightness can be adjusted.
