45Extension cord — Tohelp prevent electric shock, do not use a
polarized AC power plug with an extension cord, receptacle, or other outlet unless the polarized plug can be completely inserted to prevent exposure of the blades of the plug. When not in use — Unplug the AC power plug from the power socket if the unit will not be used for several months or more. When the cord isplugged in, a small amount of current continues to flow to the unit,even when the power is turned off.
Outdoor Antenna 1 Power lines — When connecting an outdoor antenna, make
sure it is located away from power lines.
2 Outdoor antenna grounding — Be sure the antenna system
is properly grounded to provide protection against unexpected voltage surges or static electricity build-up. Article 810 of the National Electrical Code, ANSVNFPA 70, provides information on proper grounding of the mast, supporting structure, and the lead-in wire to the antenna discharge unit, as well as the size of the grounding unit, connection to grounding terminals, and requirements for grounding terminals.

Occasional care and maintenance of the unit and the software are needed to optimize the performance of your unit.
If the unit fails to perform as described in these Operating Instructions, check the following guide.
To clean the cabinet
Use a soft and dry cloth. If the surfaces are extremely dirty, use a soft cloth lightly moistened with mild detergent solution. Do not use strong solvents, such as alcohol, benzine or thinner as these could damage the finish of the unit.
To clean the heads and tape paths After every 10 hours of use, clean the heads and tape paths with a head cleaning cassette or cotton swab moistened with cleaning fluid or denatured alcohol. (These cleaning kits are
commercially available.) When cleaning with a cotton swab, wipe the recordinglplayback
head, erasure head, capstans, and pinchrollers.
Recording/
c
Pinchroller
After cleaning the heads and tape paths with a liquid head cleaning cassette or a moistened swab, wait until the cleaned parts are completely dry before inserting the tapes.
To demagnetize the heads
The heads may become magnetized after long-term use. This
may narrow the output range of recorded tapes and increase noise. After 20 to 30 hours use, demagnetize the heads with any
commercially available demagnetizer.
