Notes on batteries
Incorrect battery usage may lead to leakage of
battery fluid or bursting batteries. To prevent
such accidents, observe the following
precautions:
• Install the + and – poles of the batteries
correctly.
• Do not try to recharge dry battery.
• When the recorder is not to be used for a long
time, be sure to remove the batteries.
• If a battery leak should develop, carefully and
thoroughly wipe away battery fluid from the
battery compartment before inserting new
ones.
Note on mechanical noise
The recorder gives off mechanical noise while
operating, which is caused by the power-saving
system of the recorder and it is not a problem.
To protect a recorded MD
To record-protect an MD, slide open the tab at
the side of the MD. In this position, the MD
cannot be recorded. To record again, slide the
tab back so the tab is visible.
