body or chassis.
• Cover the unused leads with insulating tape to prevent them from
short circuiting.
• DO NOT disassemble the unit since there are no user serviceable
parts inside.
• To keep the heat dissipation mechanism running effectively, wipe
the accumulated dust off periodically.
• Listening to the tape, radio, CD or digital audio player, etc. with
