Troubleshooting
System Reset
In rare cases the P-2000’s internal processor may freeze or lock-up causing
abnormal operation. This is common to all micro-processor controlled
devices particularly if the unit has been subjected to excessive static dis-
charge, AC line noise, or power spikes.
In most cases it is easy to solve this problem by simply unplugging the P-2000
from its AC power source for about ve minutes. After waiting, reconnect the
power cord and turn the unit on. If the unit functions normally, no further
action is needed.
In the event that the unit still does not operate properly, it may be necessary
to manually reset the processor. Note, however, that when the processor is
reset you will lose all settings including digital audio assignments, surround
mode settings, speaker congurations, tuner presets and any other memory
items. For this reason we strongly recommend that you record these settings

on the chart provided on page 18 of this manual so that it is easy to restore
them after resetting the processor.
To reset the unit you must rst remove the volume control knob on the front
panel by grasping it and gently pulling the knob straight out towards you.
When the knob is removed you will see a very small hole in the aluminum
front panel at the “nine o’clock” position. With the unit on, use a toothpick or
unfolded paper clip to gently press the button behind the opening. Hold the
button in for a second and then release it. This should reset the system.
Replace the volume control knob, being careful to line up the at surface on
the control shaft with the matching at surface on the inside of the knob.
Push the knob straight on to the shaft until it is rmly seated.
If the manual reset does not solve the problem, contact Atlantic Technology
for further advice.
