FIRMWARE UPDATE
The PAA3X allows for rmware updates which
will be periodically available through Phonic’s
website (www.phonic.com).
OPERATING TIPS
● If you feel a function is not working, rst make
sure you’ve selected the correct Input Source
in the Settings menu. Throwing the PAA3X
at the wall solves nothing.
● Capture your readings quickly using the
screen cap button. The right-most button
will immediately save a screen shot to any
FAT-32 formatted SD card you have inserted.
● If the signal clips, adjust the display range.
A higher display range will prevent the unit
from clipping when signals go higher than
the current display ceiling.
● It is not recommended that you continue us-
ing PAA3X for any measurements when the
battery is low. Always ensure you have the
charger on hand, just in case.
● Push and hold the power button for 3 seconds
to turn the unit on and o. In the unlikely event
that the PAA3X crashes, push and hold the
power button for 10 seconds to turn it o.
● Using the jog wheel is the fastest way to
control the PAA3X. Getting familiar with it
will save you a lot of time in the long run.
● If you will be reading measurements o the
PAA3X over a long period of time, be sure to
turn the system’s sleep mode ‘o’, otherwise
the screen will go dark after a few minutes.
This is done through the Utility menu found
in the Main menu.
● When testing sound pressure, the MAX
(maximum sound pressure level) eld can
be reset by simply scrolling to it and hitting
enter when it’s highlighted.
● The PAA3X can only be charged through the
USB connector. This may be done using the
included adapter.
● When the PAA3X is charging, the power
LED on the side will ash. This LED will stop
ashing when the battery is fully charged.
