3. Precautions
3A. General
•
•
The output of this system is not to be considered a diagnostic measure of the extent of disease in
the patient, nor the recommended source of therapy.
Failure to thoroughly review and adhere to the information contained in this User and Service
Manual may pose a potential hazard to the patient and/or user and may void the warranty.
3B. Control Unit, Battery, and Charger
•
•
•
•
•
•
•
•
•
During system use, maintain electrical isolation of the patient. Do not connect the probe, cable (if
used), or the internal circuit of the control unit to earth ground, or to other voltage potentials.
Maintain patient electrical isolation. Do not defeat the electrical isolation of the surface of a probe
cable (if used), and the control unit housing. These isolate the battery-power circuit inside the
control unit, the conductors inside the probe cable, the probe surface, and the patient.
When optional system components are used with the system, maintain probe and patient electrical
isolation from earth ground. The optional components include the Co-Pilot™ Device, the probe
drape, the Top Gun™ Collimator, and Navigator 2.0 cart.
In the operating room, use the charger at a distance of six feet or greater from the patient. The
charger has a rating in the United States of a "patient proximity charger.”
Fully charge the battery before use in the system.
Replace the wireless probe battery with a new battery on EACH day of use, before the first surgical
procedure.
This system is not designed for use in an explosive atmosphere.
Keep the control unit off when changing connections between the probe, cable, control unit and
gain module, when used. Control unit should also be off when inserting battery into Wireless Pilot
Probe.
The control unit, cables, batteries, charger, and probes are sold non-sterile.
3C. Probe
•
•
•
•
•
•
DO NOT put any probe or probe cable in an autoclave.
With the exception of the Wireless Pilot Probe’s battery bay, DO NOT attempt to open probes.
o All probes are tested and sealed at the factory. Attempting to open the probe may cause
damage and will void the warranty.
Remove probe battery before cleaning Wireless Pilot Probe.
DO NOT drop the probe.
DO NOT strike the probe tip against a hard surface; the detector element may become damaged and
no longer be able to measure radiation.
o This will also void the warranty.
When using the 12mm probe, DO NOT place it on, or near, a magnetic instrument pad.
3C-1. Laparoscopic and Thoracoscopic Probe Use
•
This User/Service manual is designed to assist the use of the Navigator 2.0 system and is not a
reference to surgical techniques. For information on endoscopic procedures, techniques,
complications and hazards, please reference the following publications: Surgical Laparoscopy (Zuker
KA ed. St. Louis MO 1991) and Endoscopic Surgery (White RA Klein SR, Mosby Year Book Inc. St Louis

techniques are generally contraindicated. Please reference Textbook of Laparoscopy (Hulka JF.
Grunda and Stratton, Inc. Orlando FL 1985 op114-116) for information on absolute
contraindications, high-risk patients and low-risk patients.
The use of the Navigator 2.0 system with laparoscopy should only be attempted where there is
adequate visualization of the target tissue.
Trocars should be placed in accordance with standard laparoscopic and thoracoscopic techniques,
with specific regard to target organ geometry to assure probe access to the target organ. Please
reference current trocar labeling, suggesting working knowledge of laparoscopic techniques and
familiarization with trocar placements under direct visualization through a laparoscope.
CAUTION: Endoscopic procedures should be performed only by physicians with adequate
training and familiarity with endoscopic techniques. Medical literature should be consulted
relative to techniques, complications, and hazards, prior to the performance of endoscopic
procedures.

The control unit contains the display, the battery, and most of the system controls. These system controls
are located on the front and back of the control unit.
The control unit allows the user to adjust the system’s settings and produces signal outputs in the form of a
count rate, viewable in the display, as well as an audible pitch that represents the intensity of a probe’s
signal.
The number of gamma photons (called “events”) shown in the control unit display is determined primarily
by a probe and the probe’s position (with respect to the radioactively-tagged tissue), and secondarily by the
position of the controls on the control unit.

Description
Power button: Turns power on and off.
Volume knob: Increases/decreases the volume of the
audible signal.
Display Screen: When turned on, displays the photon count
per second. Upon completion of a 10-second count, the total
number of photons detected will show on the display screen
for 4 seconds, and then the display returns to showing
counts per second.
Isotope Indicator: Indicates the isotope selected. Isotopes
detected on the Navigator 2.0 are I125, 511keV (for I-131 or
FDG-18), In111, and Tc99.
Range Settings: Adjusts the audible pitch, based on density
of events detected:
1x – Low event rates; all events are heard.
10x – Medium event rates; 1 in 10 events are heard.
100x – High event rates; 1 in 100 events are heard.
Pressing the Range button cycles through the ranges; Select
the one most useful to the procedure being performed.
NOTE: Range selection only controls pitch of the sound
generated by the unit; it has no effect on count rates
displayed or signal conditioning.
Threshold: For CABLED PROBES only, it controls the count
range of photon energy detected by the probe.
When the Threshold is off, the indicator is not illuminated,
and all photon energy, including scattered photons, is
detected.
When the Threshold is on, the indicator is illuminated. In this
setting, the detection of scattered photons is reduced or
eliminated. Signals of amplitude outside the pre-configured
energy range are discarded. Only those events within the
particular energy range are counted and displayed.
NOTE: The Threshold is normally on when using probes. The
Threshold may be set to off to count all events detected by a
cabled probe. (The Wireless Pilot Probe features integrated
threshold)

4C-1. 3mm Diameter Cable (Part # PM-4000-20) and Gain Module (Part # PM-0400-40)
The 12mm Lymphatic Mapping Probe uses a cable that has two conductors and an outside diameter of
approximately 3mm. It also uses a Gain Module (pictured below), which connects the control unit to the
probe cable.
1. Connect the 3mm Diameter Cable to the probe, matching the red indicator dot on the probe to the
red indicator dot on the cable.
2. Connect the other end of the 3mm Diameter Cable to the gain module, matching the red indicator
dot on the cable to the gain module’s cable input port.
3. Connect the gain module to the control unit, matching the arrows on the gain module cable
connector to the arrow above the signal input port. The gain module connector will “click” when it is
seated properly.

The connector has a locking mechanism. To disconnect the cable from the probe and from the gain module,
pull directly back on the hood; DO NOT pull or twist the connector jacket.
4C-2. 6mm Diameter Cable (Part # GP-4001-00)
A different cable is used for the standard lymphatic mapping probes (straight or angled), Superficial Head &
Neck Probe, laparoscopic probes, and the Daniel™ Lung Probe. This cable has five receptacles inside the
probe end, and seven pins inside the plug, that connect to the control unit. The cable is approximately 6mm
in diameter.
Connect the cable to the control unit, matching the arrows on the cable connector to the arrow above the
signal input port.
The connector is a locking connector. To disconnect the cable from the probe and from the control unit, pull
directly back on the hood; DO NOT pull or twist on the jacket.
WARNING! Do not pull or twist the jacket of the cable, to remove from control unit. You must pull on the
hood at the end of the cable. Pulling or twisting the jacket may damage the cable and
render it unusable.
4D. Optional Co-Pilot™ Device (Part # GP-6801-00)
The optional Co-Pilot is a single-use device used for initiating counting periods and adjusting the audible
range from the probe, inside the sterile field. It includes two small buttons, and a long, small-diameter cable.
To plug in the Co-Pilot, match the spacing of the prongs with the spacing of the receptacles on the control
unit. It should then be clipped onto the base of the probe.
The Co-Pilot is supplied sterile and may be used inside or outside of the sterile drape.

Threshold
For Cabled Probes only, this feature increases specificity when only a low number of
events are observed. Threshold control defaults to ON. When ON, the system counts
only the events in a narrow energy range around the signal. Change Threshold to OFF to
allow the system to count all signals it detects, opening the value range to scatter.
(NOTE: The Wireless Pilot Probe features integrated threshold.)
Range
The Range function defaults to 1X, meaning that the audible signal fluctuates according
to every single count it detects. In the 10X position, every 10th event produces an
audible output. In 100X, only every 100th event produces an audible output.
The Range control only affects the sound. The count shown in the display is
independent of the range setting.

6. Probe Connectivity and Use
6A. Navigator 2.0 with Wireless Pilot Probe
The Wireless Pilot Probe is used in various procedures. A typical sequence of setting up the Wireless Pilot
Probe for a procedure with a Technetium-99m isotope (such that may be used in a lymphatic mapping
procedure for a sentinel node biopsy) is as follows:
6A-1. Before Surgery
•
•
•
•
•
Insert a charged battery into control unit (see Section 4B-1).
Upon initial insertion of new Wireless Pilot Probe battery, probe may need to be lightly shaken to
activate LED in probe base.
LED on the Pilot Probe indicates that it is linked with control unit and ready for use. When placed in
a resting position, the LED turns off within seconds, to save energy. When the Pilot Probe is moved,
it instantly powers up for immediate use.
For intraoperative use, insert the Wireless Pilot Probe into a sterile drape.
Insert a probe battery into the Pilot Probe as follows:
1. Hold probe firm; turn battery cap counterclockwise and remove from probe. Inspect O-ring
integrity. If O-ring is missing or damaged, use new battery cap. Contact Dilon Technologies or
your distributor for battery cap reorder information.
N2-5000-07-001 Rev 2

Revised 10/21/2015
Navigator 2.0 User Manual & Service Guide
2. Install 3V CR 2 lithium battery in Pilot Probe battery holder with positive (+) end facing toward
the base of the probe and negative (-) end toward the middle of the probe. Incorrect
placement of battery into battery holder for extended periods of time will cause battery to
drain quickly.
3. Insert battery holder into probe negative (-) end in. Lightly turn until holder lowers into place.
4. Hold probe firm; push battery cap into probe and turn clockwise until O-ring is no longer visible.

7. Running the Peak Procedure: 12mm Lymphatic Mapping
Probe Only
It is important to note that the 12mm Lymphatic Mapping Probe DOES NOT use the ‘Calibration Verification
Quick Test’ referenced later in section 11B – instead, the probe-control unit configuration is brought to its
highest sensitivity point via the ‘Peak Procedure,’ described below.
7A. Running a Peak Procedure
A Peak Procedure finds the best “sensitivity” of a probe when “paired” with a control unit. The setting on
the gain module at which the probe counts the most events.
Adjusting the gain module dial increases/decreases the count rate in the Navigator 2.0 Display. Starting with
the control unit turned on and the dial in the full counter-clockwise position (0), the location on the gain
module dial where the count rate reaches its maximum value is called the Peak Setting. The system should
then be left in this setting for any subsequent procedures that day.
The probe must be held in a fixed position with respect to an isotope source during a Peak Procedure. This
source can be either a check source or the injection site (or some other region of high activity) of the
patient.
Only the Navigator 12mm Lymphatic Mapping Probe requires a Peak Procedure, because it is the only probe
that uses the gain module. The Peak Procedure should be performed on EACH day of use, before the first
surgical procedure.

11A. Overview
While the Navigator 2.0 System is virtually maintenance-free, the user should follow a number of steps to
ensure proper performance prior to each use.
1. Check each system component for any visible signs of abuse, neglect, or wear, before each use and
storage. This includes checking the following components and these features:

•
Should abnormalities be discovered, contact your sales representative or Dilon Technologies
directly.
Do not use a damaged control unit, battery, battery charger, probe, cable, or gain module.
2. Check each battery for function and charge before use. Should abnormalities be discovered, contact
your sales representative or customer support person.
3. To ensure proper functionality, follow each step as outlined in Section 4: “Control unit, Battery, and
Co-Pilot,” and the section in the manual pertaining to the relevant probe.
4. In addition to the above, preventive maintenance suggests that every two years a new battery, fuse
and cable (if used) might be considered.
5. User maintenance for the Wireless Pilot Probe is restricted to battery and battery cap replacement.
There are no user serviceable components or items on the Pilot Probe. Do not attempt to repair
damaged battery contacts, or any other damage to the probe.
WARNING! No modification of this equipment is allowed. Any modification to this will void any remaining
warranty, if attempted.
11B. Verification of Standard Gain (Calibration Quick Test)
The Navigator 2.0 system is designed to minimize periodic maintenance, such that would be performed by a
clinical engineering department or the manufacturer. Depending on the probe used, one of two procedures
can be performed by the user.
11B-1. Verification of Standard Gain (Calibration Quick Test) - Background
For CABLED PROBES only. Applies to the Standard Lymphatic Mapping Probes (SP-2A14-67 & SP-2S14-67),
Superficial Head & Neck Probe (SP-2S11-53), Laparoscopic Probes (SP-2S10-19 and SP-2S10-31), and the
Daniel™ Lung Probe (SP-2S10-31D).. Some institutions perform this Verification of Standard Gain every six
months or every year. The procedure does not calibrate the system; it simply reveals whether or not the
probe and control unit are set to a common gain standard (calibration). That common standard relates the

Navigator 2.0 User Manual & Service Guide
gamma photon energy detected by the probe to an energy window inside the control unit.
The Verification of Standard Gain uses 122 keV energy photons produced by the Isotope of Cobalt-57, to
create a known signal in the probe. The control unit expects these detected photons to be in an energy
window corresponding to the CENTERED (>0<) position of the test. The control unit also has a test setting for
an energy window BELOW (-) the expected signal, and an energy window for a signal ABOVE (+) the
expected signal. The desired outcome of the test is that the signal is greatest in the CENTERED (>0<)
position, as revealed by the highest count rate seen in the control unit’s display. The details of the test are
given below.
11B-2. Verification of Standard Gain (Calibration Quick Test) – Procedure. For CABLED PROBES only.
1. Clean the PROBE and, if used, the CABLE.
2. Charge the BATTERY, and install it into the CONTROL UNIT.
3. Place the system controls as indicated in Table 11B-2, “System Configuration - Cobalt-57 Alignment”.
4. Align a 57 Cobalt source directly with the probe tip. Maintain this exact position between the source
and the probe tip for the duration of the test.
5. Place the system controls as indicated in Table 11B-2 “System Configuration - Cobalt-57 Alignment.”
6. Place the SCAN/Calibrate Control in the CENTERED position, which is indicated by the following
symbol on the SCAN/Calibrate Control (>0<). Obtain a ten-second count. Record this total.
7. Place the SCAN/Calibrate Control in the BELOW position which is indicated by the following symbol
on the SCAN/Calibrate Control ( - ). Press the COUNT control to obtain a ten-second count. Record
this total.
8. Place the SCAN/Calibrate Control in the ABOVE position which is indicated by the following symbol
on the SCAN/Calibrate Control ( + ). Obtain a ten-second count. Record this total.
9. The highest count should be when the SCAN/Calibrate Control is in the CENTERED (>0<) position.
The count in the ABOVE position ( + ) and the count in the BELOW position ( - ) should be less than
the count in the CENTERED ( >0< ) position. The observance of these relationships verifies that the
probe and control unit have the same standard gain.
10. Return the SCAN/Calibrate Control to the SCAN position.
11. Return the other system controls to the settings for normal use.
12. End of Test.

NOTE: The front panel CALIBRATION INDICATOR blinks when the SCAN/Calibrate Control is in either the
BELOW ( - ), CENTERED (>0<), or ABOVE ( + ) test position. The CALIBRATION INDICATOR is OFF when
the CALIBRATION control is in the SCAN position.
NOTE: All Dilon Technologies probes can be used with any Navigator 2.0 control unit. The 12mm
Lymphatic Mapping Probe, used with a Gain Module, requires a different method of peak
calibration assurance, detailed in the section 7A, entitled “Running a Peak Procedure".”
11C. Fuse Replacement Procedure
The fuse is to be replaced when necessary by the user (when the fuse is "blown"). The Navigator 2.0 fuse is
to be replaced as follows:
1. Push-in and twist the fuse holder cap counter-clockwise.
2. Remove the fuse from the fuse holder.
3. Insert a new fuse into the holder.

12. Repair
Probes are sealed at the factory. No user serviceable parts are inside the probes. Damage to a probe may
result if a probe is opened by the user and will void any remaining warranty, if attempted.
Serviceable parts on the Navigator 2.0 control unit include a fuse, which may be inspected and replaced by
the user, and a replaceable battery. Beyond these two items, the control unit contains no user serviceable
parts and should not be opened by the user.
Please contact Dilon Technologies for additional service. An RMA number is required upon return for
service.
If the device cannot be repaired and or it is determined that its useful life is at an end, contact Dilon
