Plantronics Calisto 620-M - Manual (Page 18)

Can I sync multiple Calisto 620-Ms
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-M in my car? Theoretically yes, but Calisto 620-M is not designed to be used in
a car.
My Calisto 620-M carrying case is
too small to carry the wall charger
and USB cable. The Calisto 620-M 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.
