SERVICE PROCEDURES

3.1

General service information

Field service of the hemodynamic modules is limited to replacing faulty printed circuit boards or

mechanical parts. Faulty printed circuit boards should be returned to Datex-Ohmeda for repair.
Datex-Ohmeda is always available for service advice. Please provide the unit serial number, full

type designation, and a detailed description of the fault.

CAUTION

Only trained personnel with appropriate equipment should perform the tests and repairs outlined in

this section. Unauthorized service may void warranty of the unit.

3.2

Service check

These instructions include complete procedures for service check. The service check is

recommended to be performed after any service repair, however, the service check procedures can

be used also for determining possible failures.
The procedures should be performed in ascending order.
The instructions include a check form (

Appendix A

) which should be filled in when performing the

procedures.

The mark

in the instructions means that the performed procedure should be signed in the

check form.
The procedures are designed for monitors with S/5 monitor software of revision 01. However, most

of the procedures also apply to monitors, which contain some other monitor software

type/revision.
