Plantronics Calisto 620 - Manual (Page 17)

Can I sync multiple Calisto 620s to
one USB adapter (to cover a large
area)? No. The current adapter is designed for a one-to-one connection.
Can I use Calisto 620 in my car? Theoretically yes, but Calisto 620 is not designed to be used in a
car.
My Calisto 620 carrying case is too
small to carry the wall charger and
USB cable. The Calisto 620 carrying case is form-fitting to the
speakerphone and is designed to protect the speakerphone only.
The wall charger and USB cable are very durable, and can be
readily carried in a computer bag, zipper pocket, etc., without
concern for damage.
