ELECTRICAL SAFETY ISSUES
Pay close attention to these important electrical and safety
issues.
The JM-1P requires a grounded outlet. Always use a
grounded outlet and plug.
Do not use a ground-lifting adapter or cut the AC cable
ground pin.
Do not exceed the current capability of the 20-amp AC
Input connector for the loudspeaker. When looping loud-
speakers, consider the total current draw for all loud-
speakers on the circuit, including the first loudspeaker.
Make sure the AC power cable for the loudspeaker has
the appropriate power plug (on the other end) for the
area in which you will operate the loudspeaker. In addi-
tion, the AC power cable must be rated for the total cur-
rent draw of all loudspeakers looped from the power
source.
Do not operate the unit if the power cables are frayed or
broken.
Keep all liquids away from the JM-1P to avoid hazards
from electrical shock.
