MAGNETIC FIELD
CAUTION! Do not locate sensitive high gain equipment
such as pre-amplifiers or tape decks dirctly above or
below the unit. Because this amplifier has a high power
density, it has a strong magnetic field which can induce
hum into unshielded devices that are located nearby.
The field is strongest just above and below the unit.
If an equipment rack is used, we recommend locating the
amplifier(s) in the bottom of the rack and the pre-amplifier
or other sensitive equipment at the top.
WATCH FOR THESE SYMBOLS:
The exclamation point triangle is used to alert the user
to important operating or maintenance instructions.
The lightning bolt triangle is used to alert the user to
the risk of electric shock.
