Plug the power lead into a 220 - 230 V, 50 Hz, earthed (2-prong) AC
outlet.
Caution: The mains outlet (socket outlet) should be installed near the
equipment and be easily accessable.
Note: If your area experiences a high incidence of lightning or power
surges, we recommend that you install surge protectors for the
power and telephone lines. Surge protectors can be purchased from
your dealer or at most telephone specialty stores.
