Inspecting the Cables and Cords
1 Examine all system cables, the power plug and cord for damage. Make sure that the prongs of the
plug do not move in the casing. If damaged, replace it with an appropriate Philips power cord.
2 Inspect the patient cables, leads and their strain reliefs for general condition. Make sure there are
no breaks in the insulation. Make sure that the connectors are properly engaged at each end to
prevent rotation or other strain.
3 Apply the transducer or electrodes to the patient, and with the monitor switched on, flex the
patient cables near each end to make sure that there are no intermittent faults.
Maintenance Task and Test Schedule
The following tasks are for Philips-qualified service professionals only. All maintenance tasks and
performance tests are documented in detail in the service documentation supplied on the monitor
documentation DVD.
Ensure that these tasks are carried out as indicated by the monitor's maintenance schedule, or as
specified by local laws. Contact a Philips-qualified service provider if your monitor needs a safety or
performance test. Clean and disinfect equipment to decontaminate it before testing or maintaining it.
Troubleshooting
