Instruction Manual PC-USB
Electronic Control unit with USB for one LUNT Pressure-Tuner system
The PC-USB is a microprocessor controlled pressure control system for the LUNT Pressure-
Tuner (PT) tuning technique. All existing LUNT Pressure-Tuner systems can be retrofitted to the
PC-USB controller via an included adapter. The controller can be manually operated, or via a
computer by USB connection.

Power connection and charging the internal battery
The PC-USB controller needs 15 V DC. The controller can be connected to a power socket with
100 to 240 V AC by using the included AC adapter. Simply insert the supplied AC adapter into
the power connection located at the front of the PC-USB (labeled with “15 VDC”).
The PC-USB controller can also operate using the internal battery. If the PC-USB controller is
connected with an external power source, the internal battery will start charging and the
indicator light “Charging” will illuminate. The battery will also continue charging if the PC-USB
controller is off. After a full charge is performed the PC-USB controller should operate for more
than 8 hours under normal conditions without external power source.
The charger circuit will stop when the battery has reached full capacity. The AC adapter could
also be left in indefinitely if necessary.
