It is not possible to write to a preset program.
3.Reloading the factory programs
While holding down the RHYTHM/AUX PITCH
button and the ▲ button, turn on the power.
The LCD will ask “RELOAD?”
If you press the ENTER/REC button, the facto-
ry-set programs will be re-loaded into the user
program area. The display will indicate “RE-
LOAD”, “VERIFY”, “COMPLT” for a short time,
and then the power-on screen will appear.
Never turn off the power during the reload op-
eration.
If you decide not to reload, press the EXIT but-
ton while the “RELOAD?” indication is still shown.
The power-on screen will appear (without reload-
ing), and then you will enter Play mode.
Be aware that if you reload the factory pro-
grams, the user programs and any settings that
are remembered when the power is turned off
(master level etc.) will all be overwritten.
Troubleshooting
If the PX4A does not operate as you expect,
please check the following points first. If this does
not resolve the problem, contact your dealer.
1.Power does not turn on.
• Are batteries installed? Is the correct polar-
ity observed? Alternatively, is the correct AC
adapter connected to an AC outlet?
2.No sound
• Are your guitar, amp or headphones con-
nected to the correct jacks?
• Is your amp turned on and set correctly?
• Are any cables broken?
• Is the master level of the PX4A set to “0” or
to a low level?
• The VOLUME control knob may have been
turned down.
• Is the PX4A muted?
Take note that if all effects are off, the chain
display will disappear, and it will not be pos-
sible to distinguish Bypass or Mute from the
LCD display.
