TROUBLESHOOTING
My power cable does not reach the wall
outlet. Can I use any extension cord to
make it reach?
No, Panamax extension cords are the only
extension cords that you can use while keeping
your warranty valid.
The provided coax or telephone jumper
cables are not long enough to reach my
equipment. Can I use other cables?
Yes, any length cable of the same type is fine.
There is an audible buzz/hum coming
from my Max 7500-Pro. What is the
cause of this and how do I make it go
away?
This can be caused by certain appliances; most
commonly lamps with High-Low dimmer switch-
es and some room heaters, which use only half
of the AC sine wave. These appliances distort
the AC wave through a small DC bias placed on
the AC supply. Some custom audio equipment-
especially amplifiers with toroidal power trans-
formers, may react unfavorably to this distortion,
and buzz. The Max 7500-Pro’s isolation trans-
former will remove this waveform distortion and
protect the loads plugged into the bank 3 and 4
outlets. If the distortion is bad, you may actually
hear the Max 7500-Pro buzzing slightly as it
works to correct the AC power. The best way to
stop the buzz is to find the source of the distur-
bance (most likely a quartz lamp) and plug it
into a different branch circuit. Panamax
Technical Support will be glad to help you if you
have any questions about this.
The 6 Amp, Isolation Transformer circuit
breaker continually trips. What is the
problem?
The four Isolation Transformer outlets share the
720 VA Isolation transformer for their power
source. The connected equipment plugged into
the four outlets are drawing more than 6 Amps
collectively, causing the circuit breaker to trip.
These four outlets are designed specifically for
low-current, digital source components. Check
to see if you have connected a high current
amplifier or subwoofer to the Isolation
Transformer Outlets. If so, unplug the high cur-
rent components and plug them into the High
Current Outlet Bank.
Some banks are not switching ON or OFF
with the MAX 7500-Pro. How can I fix
this?
These outlets may be set as either delayed or
always-on outlets. The 2-position switches on
the back panel control this. Change the setting
of this switch from always-on to delayed. This
will allow the corresponding banks to be
switched on/off.
I connected the LED Convenience Lamp
and the lamp will not work. What is the
problem?
Check to see if the MAX 7500-Pro is in an
unsafe voltage condition by looking to see if the
unsafe voltage indicator is flashing. If the indi-
cator is flashing, then wait until voltage is back
to normal and the light will turn back on. If the
unsafe voltage indicator is OFF and the light is
still not on, call Panamax Customer Service for
help.
