These instructions include a Check Form
corresponding procedures.

The symbol
check form.

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

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.

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.

3. Clean or replace the F-CU8 fan filter.

Remove any paper chaff from the paper compartment.

Planned maintenance instructions

Clean the thermal printhead and the small glass window in front of the static brush with a
cotton swab dipped in isopropyl alcohol, if necessary.

NOTE: Avoid contact with the rubber paper roller. Be careful to limit the application of
alcohol to the thermal printhead and the window.

Reinstall the paper roll.

?

2.1.7 Modules with NIBP measurement

1. Check the NIBP pump filter. Replace the filter, if necessary.

2.2 Functional Inspection

2.2.1 General

1. Connect the mains power cord to the F-CU8.

Check that the stand-by LED is lit.

2. Switch the monitor on.
Check that the monitor starts up properly, i.e. the alarm LEDs turn on and off, normal start-

up sound is heard from the loudspeaker and monitoring screen appears.
No error messages should appear onto the screen.

3. Check that all of the connected modules are recognized, i.e. the required parameter
information is shown on the screen.

If the Recorder Module, M-REC, is connected, the module should record two lines of start­up information.

Preset measurement settings for those parameters that are connected are, for example:
