The keys on the remote control function in
the same way as the keys on the front
panel of the casette deck (please see the
previous page for the function of each key).
This remote control operates within a
distance of 7 meters while directly in front
of the unit and at an angle of up to 30
degrees. Strong fluorescent lighting or
sunlight in the room may shorten this
range, as will dust or dirt which may
accumulate on the remote control lens or
the front panel remote sensor. Also, avoid
blocking the line of sight between the
cassette deck and the remote control. The
remote control is powered by two AA
batteries, included in the carton. When the
batteries weaken, replace both of them at
the same time. If the remote control will be
unused for a long period of time, remove
the batteries to prevent damage from
corrosion.
