Troubleshooting - Fender PASSPORT P150 Owner's Manual

GROUNDING AND HUMS
Ground loops are one of the most
common causes of hum and buzz in
sound reinforcement systems and other
audio products. A ground loop usually
occurs if the separate pieces of
equipment are plugged into different AC
circuits. Also, if the audio wiring is placed too close
to the power cords, hums or buzzes can bleed into
the system. Likewise, improperly maintained power
and audio cables are yet another cause of
bothersome noise. In order to help minimize stray
hums and buzzes, here are some helpful hints.
1. Keep all electronics connected to the sound
system on the same electrical circuit.
2. Keep audio signal cables away from the AC
power cords.
3. Use balanced cables when applicable.
4. Always plug the Passport into a grounded AC
electrical outlet.
5. Be sure to use properly maintained cords and
cables with the Passport.
AIRFLOW FILTER CARE
Your Passport uses a system of forced
air cooling to keep the unit from
overheating and falling into protect
mode. The air filter at the base of the
power tower prevents dirt and other
materials from being pulled into the unit
and possibly damaging it. It is important to
periodically remove this filter and clean it by briskly
shaking it and/or washing it with a light soapy
solution. Avoid spilling any liquids on the operating
surface, heat sink, grille, volume and tone controls,
switches and line cord. ALWAYS unplug the
Passport before cleaning it or approaching it with
fluids. Before plugging in the Passport wait until the
unit has completely dried.

TROUBLESHOOTING

If the Passport is set up but does not
function, please check the following
items:
• Is the Passport's power cord properly plugged into
an electrical outlet?
• Is there power at the outlet?
• Is there sufficient airflow to the heatsink inside the
power tower?
• Is the air filter at the bottom of the tower dirty or
clogged?
• (If applicable) does your instrument have power?
• Are the volume control knobs on the Passport
turned above the minimum or counterclockwise
positions?
• Are the volume control knobs on your instruments
turned above their minimum position?
• Is the mic/instrument properly plugged into the
Passport?
• Is the mic/line switch at the mic line input in the
proper position?
• Is the mic/instrument turned on?
• Are your audio cables frayed, cut or damaged?
If after checking all of the above the Passport is still
not performing correctly, consult your nearest
authorized Fender Service Center.
COVERING CARE
Your Passport is housed in a rugged
plastic body for long life and lasting
good looks. To clean the Passport, use
a sponge with a light soapy solution.
As always, avoid spilling any liquids on
the operating surface, heat sink, grille,
volume and tone controls, switches and line cord.
ALWAYS unplug the Passport before cleaning it or
approaching it with fluids. Before plugging in the
Passport wait until the unit has completely dried.
