• This unit is paired with 9 or more
devices.
This unit can be paired with up to
8 devices; if a new device is
paired after 8 devices have been
paired, the device whose latest
connection time is the oldest
among the 8 paired devices is
replaced by the new one.

• When recognition of the unit by
the device to be connected is
deleted.
