LOCALIZATION PROCEDURE
1. Power on the LOCalizer Reader.
The firmware version number is displayed.
There is a brief delay while the integrated loop probe is tested.
If the Surgical probe is installed, there is a corresponding delay while it is tested.
2. Use the up and down arrows on the brightness control to adjust the screen to the
desired intensity.
3. Check the battery charge indicator to ensure there is adequate charge. It is highly encouraged to
change the batteries before each procedure. Batteries can be replaced following directions in the
"CARE AND MAINTENANCE" section.
NOTE: The LOCalizer Reader may turn ON with a critically low battery, but will not continue
operation normally.
4. Use the Loop Probe on the LOCalizer Reader to identify the general location of the Tag from the
surface of the breast. The sound level and pitch increases as the LOCalizer Reader approaches
the Tag. The scale shows the approximate distance to the nearest point of the Tag in millimeters.
When using the Loop probe the range of the LOCalizer Reader is at least 60 mm.

FIGURE 3. Assessing Tag location/position with Loop Probe using signal strength (not to scale)
NOTE: The sound and distance display rise to a maximum when the Tag is in line with and directly
under the sensing head surface (Figure 3). Identification of the Tag location can be refined by
moving the Probe until both ends of the Tag are detected.
NOTE: The Tag's unique identification number is displayed once the probe is close enough to the
implanted Tag.
5. Use the up and down arrows on the volume control to adjust the audio tone to the
desired volume.
6. If excising the Tag and lesion, plan and mark the surgical area with the approximate location
of the Tag.
7. In preparation for surgery, place the sterile LOCalizer Instrument Cover over the LOCalizer Reader
per the Instrument Cover Instructions for Use.
NOTE: The LOCalizer Reader can be used on an un-breached breast surface in a non-sterile
setting. In a sterile setting, use of the Instrument Cover is required. The Surgical Probe is only
intended for sterile use.
