!In case of any abnormality in the endo-motor functioning (noise,
shakiness, vibrations), stop using the device immediately and try to
find the cause of malfunction, basing on the information represented
in the part 11.
! This endo-motor has function of the file limit torque which lessens
probability of break during its use. In spite of it, files may break down
because of wrongly set limit torque value in the program or because of
worn-out files use. Carefully follow manufacturer’s instructions con-
cerning use of the endodontic instruments and avoid use of worn-out
and damaged files.
!Do not use instruments of “continuous” rotation in “reciprocal”
movement and vice versa.
! Do not use curved, deformed or not corresponding to the ISO file.
Use of such a file may result in injury.
!Always clean the shank of file to be set. Mud penetration into the
head clutch may cause loss of concentricity and the file clutch power
worsening, loss of the apex-locator contact.
! Do not start the micro-motor until the file is securely fixed in the
clutch head.
!Avoid inadvertent contact with rotating micro-motor parts and/or
rotating file.
!In some cases apex determination with apex-locator may be not
enough accurate and reliable (see part 8. “The fundamental operating
instructions of the apex-locator”). Make an X-ray image and base on
the information received from both methods before using the mixed

hotline @ geosoft.ru
Red light (13-fig.1) indicates that battery is being charged. When the
battery is fully charged, indicator changes color to yellow-green.
Note: Standard time for the battery charging is about 1,5 hours,
however, it depends on the battery current charge, level of its wear,
temperature. Operation and charge time of the old battery is shorter
than of a new one. In the case of meaningful reduction of the device
operation duration you should address to the service department to
replace the old battery for a new one.
6.2 Indication of the battery discharge
When the battery charge is lower than minimally allowable level
(<20%), warning “LB” indicator (2-fig.2) appears on the device
display.
Having seen such an indicator, charge the battery according to the
p.6.1.
Otherwise, when the battery charge falls to the critic level (<10%), the
device switches off automatically. You will see “LB” indicator
displaying when you try to switch the device on again.
Attention! When discharged, charge the device power supply in time.
Exclude the battery full discharge.
6.3. Power saving function
