MAINTENANCE
INTERNAL HARDWARE SERVICING
The PTS ii is designed with self-test and self-monitoring features to warn of failures. Refer to Alarm Conditions under
Section 2 Operating Instructions. Although very unlikely, modes of failure may also occur that cause erratic operation
and/or illegible displays and may or may not trigger alarms. If the maintenance, calibration, and troubleshooting
procedures do not restore normal operation, contact Delfi for service advice.
CAUTION:
Do not attempt to disassemble or open the enclosure of your PTS ii. The PTS ii is not designed to be
disassembled and serviced by anyone other than Delfi staff. Disassembly and attempted service by anyone other than
Delfi staff poses a risk of electric shock, damage to the unit, and injury to the patient and will void all warranties. Internal
parts in the PTS ii can only be serviced at the factory by Delfi staff. Please contact Delfi if you have problems with your
PTS ii that cannot be resolved by following the maintenance and troubleshooting procedures described above
