AC ADAPTOR PRECAUTIONS
USE THE AC POWER ADAPTOR ONLY AFTER READING AND
UNDERSTANDING THE FOLLOWING PRECAUTIONS.
HUSKY AC Adaptors are class II (double insulated with no earth) and built to
EN60950: 1988 or EN60742: 1989, BS415 and DIR73/23/EEC safety
requirements, and international EMC standards including EN55022 classes
A & B.
HUSKY AC Adaptors supplied for use in North America meet UL safety
requirements, FCC Part 15 EMC regulations (classes A and B) and CSA
EMC regulations (classes A and B).
•Hazardous voltages inside, do not attempt to open.
•No user serviceable parts inside, do not attempt to open.
•Indoor use only.
•Avoid liquid spillage, do not connect if suspected damp.
•Ensure ventilation is not restricted.
•Use only the HUSKY MP2500 AC Adaptor. This special adaptor should
never be replaced by an alternative unapproved model, as damage may
result.
•Inspect adaptor before connecting, do not use if there are signs of
damage or deterioration.
•Ensure rechargeable batteries are fitted and they are orientated
correctly.
•Battery chemical leakage is corrosive, do not touch. (In case of
accidental contact wash immediately with running water.)
•Ensure that connectors are firmly mated.
•Avoid mechanical strain to cables or connectors.
•Switch on or connect mains (line) supply only after making all
connections.
•Switch off or disconnect mains (line) supply before disconnecting.
