INTRODUCTION
1.1 About planned maintenance These instructions include procedures for a planned maintenance (PM) for Datex-Ohmeda S/5 Anesthesia Monitor and S/5 Critical Care Monitor. The Planned maintenance should be performed once a year. These instructions include a Check Form (APPENDIX A) to be filled in when performing the corresponding procedures. The symbol check form.
? in the instructions means that the performed procedure should be signed in the
The procedures should be performed in ascending order, bypassing those that are not applicable for a particular monitor. If you need further information how to perform a certain PM procedure, please refer to the corresponding slot in the Product Service Guide in the Technical Reference Manual. All menu selections related to
Datex-Ohmeda products are written in following typeface:
e.g. Parameters - More... - TONO As you enter the service menus, you need following passwords:
Monitor Setup - Install/Service (password 16-4-34) - Service (password 26-23-8) In case you evaluate the measurement accuracy with a patient simulator, add simulator’s accuracy specification to the one of the monitor. The procedures are designed for monitors with S/5 monitor software L-ANE01(A) or L-ICU01(A). However, most of the procedures also apply to monitors with older monitor software.

PLANNED MAINTENANCE CHECKLIST
2.1 Visual inspection/preparation 2.1.1 General NOTE: Wear a static control wrist strap when handling PC boards. Electrostatic discharge may damage components on the board. •
Make sure that the monitor is switched to standby. Disconnect the mains power cord from the 8-Module Frame, F-CU8. If the monitor is connected to the Datex-Ohmeda network, disconnect the Mon-Net cable from the Network Board, B-NET or UPI4NET board, B-UPI4NET. If the Memory Module, M-MEM is connected, remove any memory cards.
1.
Check all units visually. Check e.g. that all parts are intact, the cables and screws are connected and tightened properly. Especially check the following parts: Video displays : the display power cord is locked to the display. F-CU8: the equipotential tap and all the screws are tightened properly. Airway Module, G-XXXXX: the equipotential tap is tightened properly. Check that modules go in smoothly and lock up properly in all module slots.
2.
The lead-acid battery in the power supply unit is recommend to be replaced after every 4 years. Replace the battery, if necessary. The SRAM/Timekeeper battery on the CPU board is recommend to be replaced after every 8 years. Replace the battery, if necessary. NOTE: The Factory Reset should be performed if the SRAM/Timekeeper battery, or the SRAM/Timekeeper chip is replaced.
