PM-PRO POWER CONDITIONER/MONITOR
will not be tripped falsely by the transient high inrush currents often encoun-
tered when turning on large reactive loads like power amps. Its trip point is
unaffected by ambient temperature. The breaker/switch controls power to the
eight switched rear panel outlets, but does not affect the voltmeter, the amme-
ter, or the status LEDs. If it trips, reduce the load on the PM-PRO and push it
back to the ON position. (Note: The PM-PRO-E's circuit breaker is not mag-
netic.)
