$250.00 without further notification.
TROUBLESHOOTING (Continued):
• If these responses do not solve the problem, check the unit
operation by touching the file clip to the lip clip. A consistent
“LONG” display indication shows the unit is operating properly.
• If the unit is not operating properly, turn the unit off, wait 5
seconds, then turn it back on to reset. Verify the unit passes
the self-test, and repeat the above operation check.
• If the problem is still not solved, contact your local dealer or our
office listed on the back page of this manual.

TROUBLESHOOTING (Continued):
k. The canal may be extremely dry, moisten the canal with
water or sodium hypochlorite.
l. The canal may be exiting at a sharp angle. Sometimes the
file is not able to follow a sharp bend and the file cannot
be inserted any further.
9. The display indicates perforation right away or provides
imprecise, erratic or short indications.
a. Verify the pulp chamber is clean and dry.
b. The canal maybe filled with blood or electrolytic fluids. In
this case, the meter sometimes jumps when the file tip
breaks the surface of the fluid. The display will return to
normal as the file approaches the apex.
c. The tooth maybe covered with cutting debris or chemi-
cals. Clean off the surface of the tooth if so.
d. The file may be making contact with the gums or other soft
tissue in the mouth. This will cause inaccurate readings.
e. Too much pulp may be left in the canal. Sometimes a
large amount of pulp in the canal can interfere with accu-
rate readings.
f. Amalgam restorations or crowns may cause the unit to
overreact if the restoration is in contact with the file probe.
If this is the case, move the file out of contact with the
metal restoration.
g. Caries on proximal surfaces can cause inaccurate readings.
h. If a lateral canal is present, the unit may indicate apex at
the branch canal.
i. If the crown has been lowered by removal of the occlusal
surface, the possibility of electrical contact with the gums
is increased. Wash the canal with sodium hypochlorite in
this case.
j. Verify the file clip metal is clean, free of debris and corro-
sion, clean if not.
k. The unit often overreacts if the canal has an exceptionally
large foramen and is filled with an electrolytic solution.
The unit should return to normal display as the file
advances toward the apex.
l. If the unit still overreacts near the apex, dry some of the
electrolytic solution and use a larger file closer to the size
of the apex.

You’ve purchased the very latest in Apical Foramen
Location technology. Aseptico has developed a new technology
called "Impedance Vector Mapping". This approach uses a sin-
gle pure tone signal to precisely identify the electrical charac-
teristics of the endodontic file’s present position. These charac-
teristics are used to develop an index to an internally stored
collection of clinical experience regarding the electrical charac-
teristics of the Apical Foramen. This collection of clinical experi-
ence is called a "Personality Mapping" for the device.
The Endopex V is microprocessor controlled and may be oper-
ated in dry and moist tooth canals.
Congratulations!
The accuracy and efficacy of the Endopex V has been devel-
oped and affirmed via studies at a major American dental
school and in the hands of professional endodontists.
Watch for new Aseptico products that contain Impedance
Vector Personality Maps to assist in more unusual, difficult, or
special cases.
Rubber dam should be used in all endodontic cases. We rec-
ommend the use of HandiDamTM - Aseptico’s premium pre-
framed rubber dam, available online at www.aseptico.com or
contact a sales representative at 1-800-426-5913.

TROUBLESHOOTING (Continued):
b. Verify that the lip clip has a good connection to the
patient’s oral mucosa.
c. Verify the file clip metal is clean, free of debris and corro-
sion, clean if not.
d. Verify the pulp chamber is clean and dry.
6. The display indicates only when the file is very near the
apex.
a. The canal may be obstructed by dentin debris or shav-
ings. The unit will only indicate correctly when the file
passes through the apical constriction.
b. The canal may be extremely dry, moisten the canal with
water or sodium hypochlorite.
c. If the apical foramen is too large or incompletely formed,
the indication may suddenly jump as the file tip approach-
es the foramen.
7. There are no audio indications.
a. Verify audio indication has been turned on.
8. The display gives no indications or gives incorrect indi-
cations.
a. Verify that the lip clip has a good connection to the
patient’s oral mucosa.
b. Make sure all connections to the cable assembly are
secure. Specifically check the cable assembly jack is
properly inserted in the unit, the lip clip is well seated in
its receiving connector, and the file clip assembly is well
seated in its receiving connector.
c. Verify the file clip metal is clean, free of debris and corro-
sion, clean if not.
d. Verify the pulp chamber is clean and dry.
e. The file clip plastic or metal may be damaged, replace it
if so.
f. Verify the file clip is securely attached to the file and the
file is inserted in the canal.
g. Verify the canal has not been retreated with silver points.
h. Verify the apex is complete.
i. The canal may be calcified.
j. The canal may be obstructed by dentin debris or shav-
ings. The unit will only indicate correctly when the file
passes through the apical constriction.

OPERATION FUNCTIONS:
1. Power Switch – Controls power on/off to the unit. When
turned on, self-test will initiate and should illuminate a green
power L.E.D. within a few seconds to indicate a properly
functioning unit.
a. A flashing yellow L.E.D. indicates a low battery requiring
replacement.
b. The unit will automatically turn off if it fails the battery of
power on tests. Low batteries will cause self test failures.
c. If a subsequent attempt to power on succeeds, the unit
will function properly, but should still be returned for serv-
ice if it continues to automatically turn off during self test
with fresh batteries. Low batteries will cause self test fail-
ures.
2. Display Switch – Allows the selection of one of three dis-
play modes. The following modes are indicated by the illu-
mination of a corresponding L.E.D. color below the Display
Switch;
a. Single Bar March (Green) – One bar is illuminated to
indicate proximity to the apical foramen. This mode is
most conservative of battery life.
b. Logarithmic March (Yellow) – Further away from the api-
cal foramen, 3 bars will light, mid range proximities will
produce 2 illuminated bars, near proximities, apex indica-
tion and perforation indications will illuminate only one
bar or light. This mode is also conservative of battery life.
c. Persistent On March (Red) – Each illuminated bar
remains on during progression toward the apical fora-
men. This mode is least conservative of battery life, but
certainly gives the most visible indications.
3. Sound Switch – Controls sound indication on/off. The state
of the sound indication is indication by the on/off illumination
of an L.E.D. beneath the Sound Switch. When active the
following audio indications will be provided;
a. Distant proximity – silence.
b. Near proximity – 1/24th pulse chirp.
c. Impending proximity (one light bar preceding the Apex
indicating 0.5mm) – 1/3rd pulse beep.
d. Apex – 1/2 pulse beep.
e. Perforation – solid tone alarm.
TROUBLESHOOTING:
1. Nothing happens on the display after the main switch is
pressed.
a. The button should be held down firmly for two seconds to
turn the unit on.
b. Verify the battery is properly installed.
c. Verify the battery is fresh.
2. The power indicator turns red and the unit turns off after
a couple of minutes.
a. Verify the battery is fresh.
b. The first battery of self-tests has failed, wait 5 seconds,
turn the unit back on. If this does not solve the problem,
contact your local dealer or our office listed on the back
page of this manual
3. The power indicator turns yellow and the unit turns off
after a couple of minutes.
a. The second battery of self-tests has failed, wait 5 sec-
onds, turn the unit back on. If this does not solve the
problem, contact your local dealer or our office listed on
the back page of this manual
4. The power indicator is yellow and blinking.
a. Replace the battery.
5. The display gives unstable indications.
a. The file may be following the canal at a sharp angle.
When this happens, the display sometimes "jumps" to a
perforation indication. If this seems the case, retract the
file just enough so the perforation indication stops. This is
the working length.
CAUTIONS (Continued):
including the connection to the unit. A poor connection can
prevent accurate measurements.
7. Always take an x-ray to confirm the results.
8. Do not clean the main unit with Gluteraldhyde, Ethanol, or
similar chemicals to avoid discoloration and surface corro-
sion of the unit. If the unit contacts any of these chemicals,
wipe off immediately with a damp cloth.
9. Indications vary slightly depending on individual tooth char-
acteristics and canal shape; the dentist should apply clinical
judgment on each case.

DISINFECTION AND MAINTENANCE:
1. Main Unit
Wash display and outside of the enclosure with a soft cloth
using a mild detergent. Rinse off the unit by wiping with a
damp cloth. Never submerge unit or saturate with any disin-
fectant fluids.
2. Electrodes
The electrodes must be sterilized between each patient use.
Sterilize the file clip and lip clips at 132º C (270º F) for 5
minutes. Do not autoclave any other part.
3. Cable Assembly
The Cable Assembly may be wiped or dipped in a disinfec-
tant solution. Do not soak the Cable Assembly.
4. Batteries
Replace batteries with fresh cells when unit indicates low
battery when power light is yellow and blinking. From one to
three 9V batteries may be used together, for an estimated
15 hrs of battery life.
CAUTIONS:
1. Do not use this unit in conjunction with an electric scalpel or
on patients with pacemakers.
2. Replace the battery when the power light starts blinking yel-
low. Accurate readings cannot be assured with batteries that
are low on power.
3. Always remove the batteries for shipping or long-term storage.
4. Use files and reamers with a plastic (resin) handles.
5. Numbers indicating distances are for reference only. The
dentist’s judgment must be used to interpret indication
results. Clinical experience, including knowledge of root
anatomy, is crucial when interpreting indication results.
6. Always verify good connection of the lip clip to the patient’s
oral mucosa and all connections to the cable assembly
