OVERVIEW
These Plantronics®Discovery™Bluetooth Headsets combine
the latest wireless technology with a sleek design to give you
convenient hands-free call communications wherever you go.
Using Bluetooth technology, you can roam up to 33 feet
(10 m) from Bluetooth devices, such as laptops, PDAs, or
phones, that support headsets and hands-free technology.
Ultralight and ultracomfortable, Discovery headsets weigh
just a third of an ounce, fit discreetly in your ear, and include
three sizes of soft gel ear tips for a personalized fit.
For even more convenience, you can use your existing
phone charger to recharge the headset. The length of talk
time from a charge depends on the model you order. The
Discovery 640 provides up to five hours of talk time between
charges; the Discovery 645 DSP provides up to three hours
of talk time.
Both models come with four charging adapters that work
with most phone chargers, eliminating the need for a
separate charging cable. An AC adapter is also included.
What’s more, each headset system includes an innovative
charging system that uses a AAA battery charger to extend
talk time up to 15 hours for the Discovery 640 and up to 9
hours for the Discovery 645 DSP. This way, your phone is
ready when you are.
Plan to use the headset in a busy office, call center, or
other noisy environment? Then take a look at the Discovery
645 version. For optimal sound quality, it features built-in
digital signal processing (DSP) technology that actively
reduces transmitted background noise, so your voice can
be heard clearly by your caller.
Both the 640 and 645 feature a one-touch call-control
button and support last number redial, as well as voice-
activated dialing so you can place calls hands free when
you’re on the go. The headsets also support multipoint
technology, which means you can connect simultaneously
with two different Bluetooth audio devices and have calls
received on either device ring through to the headset.
With each headset, you also get an ear stabilizer for a
more secure fit and a stylish, chrome pocket case that provides
convenient and secure storage for the headset and vibrates
to alert you to incoming calls.
NOTE: Last number redial and voice-activated dialing must be
supported by your device or cellular provider.

Bluetooth.
If you use low-power radio communications to wirelessly
link phones, computers, and other network devices over short
distances, it’s likely those devices use Bluetooth technology.
Bluetooth, named for a Danish king who ruled more than
1000 years ago, is a technology that primarily supports simple
wireless networking of personal devices and peripherals like
wireless headsets, mobile phones, and PDAs. Bluetooth
devices generally communicate at speeds less than 1 Mbps
and are divided into three power classes.
Class I Bluetooth devices are considered long-range units.
They have a range of up to 100 meters (328 ft.) and a
maximum power output of 20 dBm.
Class II Bluetooth devices have a standard range of up to
10 meters (32.8 ft.) and a maximum power output of 4 dBm.
Class III Bluetooth devices are definitely built for short-
range communication, with a range of up to 10 centimeters
(3.9 in.) and a maximum power output of 0 dBm.
Bluetooth networks feature a dynamic topology called a
piconet or PAN. These networks contain a minimum of two to
a maximum of eight Bluetooth peer devices that use protocols
that are part of Bluetooth standard. The current Bluetooth
standard is version 2.0, and it’s actually the specification’s third
version, following its 1.1 and 1.2 incarnations.
Although the Bluetooth standard uses the same 2.4-GHz
range as 802.11b and 802.11g, it’s much slower than Wi-Fi,
more limited in range, and supports fewer devices.
Technically Speaking
Recognize any of these situations?
• You wait more than 30 minutes to get through
to a vendor’s tech support.
• The so-called “tech” can’t help you or gives you
the wrong answer.
• You don’t have a purchase order number and the
tech refuses to help you.
• It’s 9 p. m. and you need help, but your vendor’s
tech support line is closed.
According to a survey by Data Communications
magazine, 90% of network managers surveyed say
that getting the technical support they need is extremely
important when choosing a vendor. But even though
network managers pay anywhere from 10 to 20% of their
overall purchase price for a basic service and support
contract, the technical support and service they receive falls
far short of their expectations—and certainly isn’t worth
what they paid.
At Black Box, we guarantee the best value and the
best support. You can even consult our Technical Support
Experts before you buy if you need help selecting just
the right component for your application.
