USER MANUAL
1 Introduction
1.1 Operating Principle
The Navigator 2.0 System detects presence of gamma rays, emitted from radioactive isotopes in body
organs or tissue. System use requires the Navigator 2.0 Control Unit, which allows the user to adjust the
system's settings and produces a variety of signal outputs. The control unit is powered by a rechargeable
battery. The system provides an increasing or decreasing sound and visual counts that vary as level of
gamma radiation increases or decreases.
The control unit works in conjunction with a hand-held probe that is connected to the control unit either via
a cable or wireless technology. Placing probe close to a radiation source increases number of counts
detected and localization occurs. As the distance between the probe and the radiation source is
increases, the number of gamma rays detected decreases.
The Navigator Control Unit is used with any of the following Navigator™ hand-held probe models. The
probes differ primarily in their size, shape, detector technology and connection to the control unit.
• 14mm Wireless Pilot Probe™ (angled tip & straight tip)
• 14mm Standard Lymphatic Mapping Probes (angled tip & straight tip)
• 11mm Superficial Head & Neck Probe (straight tip)
• 10mm Daniel Lung Probe™ (straight tip)
• 10mm Laparoscopic Probes (310mm & 190mm Lengths, straight tips)
The system is supplied non-sterile. This manual includes guidelines for the use of the probes and
accessories within the sterile field.
1.2 Intended Use
For the detection and quantification of gamma radiation from gamma-emitting isotopes in the body or
tissues. Use for non-imaging procedures to measure the amount of radionuclide absorbed by a particular
organ or body region.
1.3 Indications for Use
For the detection and quantification of gamma radiation from gamma-emitting isotopes in the body or
tissues. Use for non-imaging procedures to measure the amount of radionuclide absorbed by a particular
organ or body region.
1.4 Manufacture and Distribution
The system is manufactured and distributed by Dilon Technologies of Newport News, VA. Please direct all

4 Control Unit, Battery, and Cable
4.1 Control Unit Features: Front
The control unit contains the display, the battery, and most of the system controls. These system controls
are located on the front and rear 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 on the display, as well as an audible pitch that correlates to the intensity of the
measured gamma photons.
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 radioactive sire), and secondarily by the setting of
the controls on the control unit.

4.5 Charging the Battery (Battery Charger Part # N2-8000-02)
Place the charger on a flat, level surface, away from sources of heat and moisture. Plug the DC connector
from the power supply into the back of the charger, and connect the power supply to the mains AC, using
the only the cable provided.
All of the LEDs will flash momentarily to indicate that power is present.
Place the battery into either battery bay, ensuring that the 5-way connector is fully seated. The LEDs in the
battery status window will provide charge status, and the charger will automatically begin charging. Each
charge bay operates independently, providing simultaneous charge of each battery inserted. It takes
approximately 3.5 hours to fully charge a discharged battery.
CAUTION: To avoid the risk of electric shock, the battery charger cord must only
be connected to a Supply Mains with protective earth. Mains power quality should
be that of a typical commercial or hospital environment
While there is a calibration button for each bay, calibration is not necessary for use with the Navigator
2.0. If calibration button is inadvertently pressed, either a flashing blue or solid blue light will illuminate.
Simply remove battery and reinsert in order to resume charge. A green light will indicate that it is in charge
mode.
