Pentax PocketJet 3 - Manual (Page 6)

Unplug AC Cable when Printer is Not in Use
Always unplug the AC cable from the AC power outlet when you stop
using the printer or finish charging the battery. The transformer inside
the AC adapter generates heat while it is plugged in. Unplugging the
AC adapter extends its life.
Battery Recycling/Disposal Information
This printer can run on an optional rechargeable Nickel-Metal Hydride
(NiMH) battery. The battery is recyclable. At the end of its useful life,
please consider recycling options (contact your local solid waste
officials) or proper disposal (see the paragraphs below). It may be
illegal under various state and local laws to dispose of the battery in
your solid waste collection.
The RBRC seal on the NiMH battery pack supplied for the
PocketJet 3 / 3 Plus printers indicates that Pentax is voluntarily
participating in an industry program to collect and recycle these battery
packs at the end of their useful life, when taken out of service within
the United States. The RBRC program provides a convenient
alternative to putting spent NiMH battery packs into the trash or
municipal waste stream, which is illegal in some areas.
Pentax payments to RBRC makes it easy for you to drop the spent
battery pack at local retailers of replacement NiMH batteries or at
authorized Pentax product service centers. You may also contact your
local recycling center for information on where to return the spent
battery packs. The involvement of Pentax in this program is part of its
commitment to protecting our environment and conserving natural
resources.
For users outside the United States, please contact your local reseller or
local solid waste official for information on recycling your used
batteries.
