Your new Endo DTC®is one of the most advanced units available
to the dental profession. This system features advanced digital
torque control technology with auto-stop reverse to help prevent
file breakage in the canal, five programmable memory buttons
with an onboard file library, an integrated calibration system, and
the versatility of an autoclavable 30,000 RPM brushless micro
motor. These features combine to make the perfect rotary file
system for endodontic and other dental procedures.
Congratulations
This system is engineered to provide many years of reliable
service. Please read the instructions provided in this manual to
receive the best and longest service from your Aseptico
equipment.
Separate manuals may be provided to cover the operation and
maintenance of handpieces or other accessories for your unit.

QUICK START OPERATION
After the unit has been set up, you are ready for
quick start operation as follows:
1. Turn the Power Switch on the rear panel of
the console from the 'OFF' (0) to the 'ON' (-)
position.
The Console LCD Display will light and the
Startup Screen (shown below) will be dis-
played for a few seconds. The Startup Screen
displays the software version onboard your
Endo DTC®.
ASEPTICO AEU25
Software Rev. TUL06
2. Set The Default Handpiece:
On your first use (and after Recalling Factory
Setup, see System Setup Menu page 7) you
must specify which handpiece you are using
with the Endo DTC®. This ensures accurate
torque response. The handpiece included
with your Endo DTC®has either Tul 8M or
Anthogyr 1/8* written on it.
A. The screen will display:
1/8 TUL HANDPIECE
1=next 2=ok
• If your 1/8 reduction contra-angle
handpiece is the Tul 8M model, press
Button #2 to set this as your default
handpiece, then go on to Step 3 below.
• If you do not have the Tul 8M model, press
Button #1 and go on to Step B.
B. The screen will display:
1/8 AG HANDPIECE
1=next 2=ok
• If you have the Anthogyr 1/8 handpiece,
press Button #2 to set the Anthogyr 1/8 as
your default handpiece.
3. Insert an endodontic rotary file into the
handpiece.
4. Use the Calibration function to calibrate the
Endo DTC®. See Caution at right.
Press and release the “CAL” button. The
unit will run for a few seconds, measuring
the handpiece for an accurate display of
speed and torque values.
5. Select the Preset Button corresponding to
the endodontic rotary file series you are
using.
By default, the Endo DTC®preset buttons
are set for the file series shown in Chart 1.
Pressing the Preset Button repeatedly will
cycle through the individual files listed
below each series name.
6. Press the foot pedal to activate motor and
begin operation.
When using the optional AE-7D Dual Foot
Control:
The black (right side) pedal controls the
on/off operation of the handpiece (exactly
like the standard AE-7P foot pedal).
The blue (left side) pedal provides a hands-
free way to operate the preset buttons:
• To step to the next individual file of an
entire file series on the active preset but-
ton: Press and release the blue pedal.
• To step to the next preset button: Press
and hold the blue pedal for 1/2 sec. (until
you hear a double beep), then release
the blue pedal.
7. After 20 minutes of inactivity, the Endo
DTC®will go into Sleep Mode to conserve
power. To exit Sleep Mode and resume
operation, press the Foot Pedal.
*The ratios 8:1 and 1/8 are equivalent; one is a U.S. term (8:1), one is a European term (1/8).

5
During Calibration, the
handpiece will operate,
rotating through a pre-
programmed speed
range. Before calibrating,
be sure a file or bit is
secured in the handpiece
with the collet closed.

1. HANDPIECE RATIO SELECTOR:
Sets the Handpiece Ratio Indicator on the
Console LCD Display to read accurately for
different handpiece ratios.
Multiple handpieces with different ratios are
often required to obtain the various speed
ranges used in dental procedures.
The available handpiece ratios and speed &
torque ranges for each are shown in Chart 2
below.
Chart 2 - Ratio, Speed and, Torque
Push the Handpiece Ratio Selector up or down
arrows until the displayed handpiece ratio
matches the handpiece ratio you are using.
Ratio settings are held in memory even after
unit is turned off.
Auto Stop Reverse (ASR) is not available with
Increaser handpieces.
2. SPEED (RPM) SELECTOR:
Controls the speed of the motor and
handpiece. Push the Speed Up arrow to
increase speed and the Speed Down arrow to
decrease speed. The Speed (RPM) Indicator
on the Console LCD Display shows actual
RPM. For display accuracy, the displayed
handpiece ratio must exactly match the ratio of
the handpiece being used. Speed settings are
held in memory even after unit is turned off.
3. TORQUE SELECTOR:
Allows the user to adjust exact torque limits
in Gram•Centimeter increments. Push the
Torque Selector up/down arrows until the
desired torque level is indicated on the
Console LCD Display. By adjusting the
torque control to reduced limits for each
instrument size and operating the handpiece
at a constant RPM, the risk of instrument
breakage is greatly reduced.
Torque settings are held in memory even
after unit is turned off.
For most endodontic root canal applications,
the included 1/8 reduction contra-angle
handpiece is normally used. Proper-contra
angle maintenance, including cleaning and
lubrication are essential to minimize torque
losses when using the torque reduction set-
tings.
4. FORWARD/REVERSE SELECTOR
(FWD/REV):
Determines the rotation of the motor and
handpiece. A red LED light above this button
will indicate the reverse rotation during
operation. When the Reverse Beeper (BPR)
feature is active, an audible beeper (and the
red LED light) will indicate the reverse
rotation.
5. MAXIMUM TORQUE BUTTON (MAX):
Press and release to override the Endo DTC®
Torque Control feature.
With MAX Torque activated:
The LED above the Max. Torque Button will
display a steady red light, the Torque
Indicator will display "MAX", and the motor
will operate at full torque. When the Max
function is enabled, the Auto Stop Reverse
(ASR) and torque warning tone features are
automatically disabled.
With MAX Torque disabled:
When the motor reaches the programmed
maximum torque level, the LED above the
Max. Torque Button will blink green. This is
the normal setting for endodontic procedures.
ADVANCED OPERATION AND FUNCTIONS
Note: Speed and torque ranges are accurate when
handpieces are used with the supplied 30K motor.
Handpiece Speed Torque
Ratio Range (RPM) Range (g•cm)
5/1 1,500 - 150,000 2-15 (No ASR)
1/1 TUL or AG 300 - 30,000 4 -125
1/4 75 - 7,500 15 - 500
1/8 TUL or AG 40 - 3,750 30 - 1,000

STERILIZATION AND
MAINTENANCE:
HANDPIECES - Wipe with an alcohol
gauze. Clean and lubricate handpieces
with a cleaner/lubricant after each use and
before autoclaving. This will ensure proper
operation and a long service life for your
handpiece. Do not use a cleaner/lubricant
after autoclaving, only use before
sterilization. Follow the instructions provided
with the handpiece purchased for complete
maintenance instructions.
MOTORS - The entire motor and cord
assembly supplied with your unit must be
surface sterilized by autoclave. Prevacuum
sterilize at 132º C (270º F) for 3 minutes.
Before autoclaving the motor and cord
assembly, always install the autoclaving
plug into the motor and motor connector. A
plug with sealing O-ring is supplied with
the motor. Remove the handpiece from the
motor and install plug as shown at right.
The included motor/handpiece holding
cradle is also fully autoclavable.
CONSOLE - The exterior of the console
may be cleaned by wiping with a soft cloth
moistened with mild detergent or disinfect-
ing solution.
CAUTION FOR ALL STERILIZATION:
• Do not exceed 135° C or 275° F
• Do not submerge in any solutions
• Do not use ultrasonic cleaners
• Do not attempt to disassemble
the motor or motor connector.
• Do not oil or lubricate the motor.

Failure to comply with any of the above
instructions may void your warranty
WARNING

and motor connector before autoclaving.
• If the autoclaving plug for the motor becomes
difficult to remove or install, apply silicone grease
or similar lubricant to the o-rings.
