Appendix E Using a PHD+, PHD+ II, or PHD Laser+
To charge the batteries for your PHD unit, make sure the device is turned off.
Connect the battery charger to the port (location and type of end vary from unit
to unit). Plug the battery charger into an electrical outlet.
Charge all units for 16 hours initially. Thereafter charge them for a minimum of 8
hours only when the LOW BATTERY message appears. Remove the battery
charger from the outlet, and then disconnect the charger from the PHD.
Installing a rechargeable battery pack
If you change from alkaline batteries to NiCd batteries in a PHD+ or PHD+ II, no
modification of the unit is needed.
If you purchased the rechargeable battery pack for the PHD Laser+, please follow
these instructions to install it:
1. With the unit turned off, remove the hand strap by twisting the clip at the
lower end. Then, remove the battery cover.
2. Locate the white wiring harness on the lower left side. Attached to the
harness are two wires connected to the battery and one that forms a loop.
Grasp this loop and pull up. The harness will unplug from the unit.
3. Remove the harness, wires, and 9Ćvolt battery from the unit.
4. Carefully remove the gluedĆin foam insert that surrounded the battery.
5. Place the rechargeable battery pack into the unit, making sure that it is right
side up. Check to see that the battery pack is making connection with the
contacts located in the bottom of the scanner.
Note:
Do not remove the wrapping from the batteries.
6. Replace the battery cover and hand strap.
7. Connect the recharger to the bottom of the unit and recharge the unit for a
minimum of 14 hours. The packs do not come charged from FSC. When the
unit is recharging, the red light located in the middle of the keypad should be
lit. This indicates that the unit is charging.
8. Keep the wiring harness and the foam insert. You may use it later if you wish
to convert back to alkaline batteries.
Backup power
The PHD+ contains a lithium backup battery. When the NiCd batteries are
removed, the lithium battery has a life of about 1000 hours (16 days) if the device
is not turned on. We recommend you replace the lithium battery every five years.
Note:
For information on replacing the lithium backup battery, contact the Follett
Returns Department.
The PHD+ II and PHD Laser+ contain a super capacitor (supercap). The super
capacitor provides backup power to protect the application program only long
enough for the NiCd batteries to be charged. By itself, it can only sustain the
PHD+ II/PHD Laser+ for 20 minutes of continuous use.
