Model
upgrades
The

offers

the
opportunity
to
upgrade
to
a
higher

Some
of
these
upgrades
may
be
available
as
kits
to
enable
a
Cyrus
authorised
service
agent
to
perform
the
upgrade.
In
these
cases
detailed
instructions
and
kits
of
original
parts
will
be
available
from
the
Cyrus
service

Under
no
circumstances
should
an

be
attempted
on

without

and
an
original

kit.
