available spare transponders of the types that the Allflex Pocket Reader is capable of
reading for this purpose. The chart below provides nominal read distance performance
that can be expected when the transponder is optimally oriented to the Reader.

Note
: In order to read a transponder, position the transponder as shown in Figure 3 below
within the read range specified in Table 3. Press and release the READ button. The Reader
will search for a transponder for 3 seconds (the factory set default value). If the transponder is
detected during this interval, the Red LED will flash, the audible beeper will sound, and the ID
Code will be displayed on the LCD readout. If no transponder is detected during this search
interval, there will be no audible/visual indication, and the LCD will display NO TAG FOUND.
When any tag number is read more than once, the LED and beeper indication will be a double
flash/beep indication. Holding the READ button down permits continuous scanning.
Note:
When reading installed transponders whose orientation cannot be ascertained, the
reading distance may be less than those listed in Table 3. The Reader may need to be moved
and its orientation may need to be changed in order to obtain a reading. Generally, reading such
non-visible (implanted) transponders will require such Reader movement.

Interpreting the Visual ID Codes
The Portable Reader is capable of reading the ISO HDX and FDX-B transponder
technologies, and it can be configured via the Options Menu to display the
corresponding ID Code information in 4 different formats (see Figure 4). Using the
Options Menu, the Reader can be configured to display a transponder’s Manufacturer
Code and the Identification Code, or only its Identification Code. Furthermore, the
transponder’s information can be displayed in either decimal (0 > 9) or in hexadecimal
(0 > F) representation.
Note:
The Manufacturer’s Code is displayed only for ISO compliant HDX and FDX-B
transponders that contain a decimal value in the range of 900 to 999, per ISO 11784
requirements, and per ICAR assignment. A value less than 900 is also displayed, but represents
a Country Code per ISO 11784 and ISO 3166.

Note:
The Manufacturer Code information appears on the LCD as the left-most 3 digits or 4
characters on the top line. When the LCD format has been set for hexadecimal representation, a
lower case “h” precedes the 10 digit ID Code information, except for HDX Industrial format
type transponders.
Note
: Industrial coded HDX transponder types exhibit either 16 (decimal) or 13 (hexadecimal)
characters as shown in Figure 4. It is not possible to display the 4 digit application code that is
embedded within another field in the transponder.
