Appendix E Using a PHD+, PHD+ II, or PHD Laser+
A PHD (Portable Handheld Device) is a barcode scanner that collects, stores, and
transmits data. You can use a PHD to simplify certain circulation, cataloging,
inventory, and reporting activities. Follett Software currently supports four PHD
models. This appendix provides a comparison of the three Telxont models and
instructions for their use and maintenance.
Important: This appendix is intended to complement, not duplicate, the reference
materials that came with your Telxon PHD.

PHD+, PHD+ II, and PHD Laser+: the Telxon models
Currently, Follett Software supports three Telxon PHDs: the original PHD+, the
PHD+ II (July 1993), and the PHD Laser+ (spring 1997). As the following table
shows, there are a few differences between the three models:
Feature PHD+ (PTC-620) PHD+ II (PTC-600) PHD Laser+ (PTC-960L)
Number of scans 300 to 350* 4000 to 5000* 4000 to 5000*
Number and size of batteries 4 AAA 3 AA 1 alkaline 9 volt
Backup battery lithium supercap (super
capacitor)
supercap (super capaciĆ
tor)
* These are general estimates. The actual number of scans depends on the amount of memory in the
unit. To determine the maximum scans, from the PHD main menu, press <L>. The unit's available
memory appears (in bytes). Divide this figure by 22.
The battery requirements are also different for the three units. Consult your
Telxon guide or Maintenance information" (page 668) for battery information.
