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.
