Service Mode Hardware Tests
The tests described below are accessible in Service Mode only. In Service Mode press the
Setup key and select Hardware Test to display the Hardware Test selection menu.
Coldstart Test
CAUTION Before executing a coldstart test be aware that the patient database will be erased by the test
and that the Monitor defaults will be reset to user defaults.
This coldstart test executes a reboot with a more intensive system Self-Test than a normal
reboot. The coldstart test is also executed in the Server and in the Extension if either one is
connected.
Executing the coldstart test automatically returns the Instrument to Monitoring Mode.
To execute a coldstart test, do the following:
Step 1 Switch the Monitor into Service Mode.
Step 2 Press the Setup key.
Step 3 Select Status Log.
Step 4 Clear the Status Log and Confirm (for both, Monitor and Server).
Step 5 Press Exit.
Step 6 Select Hardware Test.
Step 7 Select Coldstart.
Step 8 Press Confirm.
The Monitor (and Server, if connected) perform a reboot.
The coldstart reboot is the same as described in What Happens During a Regular Boot, AC
powered, without Battery except that the time taken from the switch off of the Alarm and
Suspend LEDs to the switch on of the backlight and display of the M3 logo is extended. The
whole reboot takes about 10 seconds.
After the system has come up again, check whether a CHECK STATUS LOG INOP is
displayed.
• If not, the test is successful.
• If yes, do the following:
• Go into the Status Log and check whether either the Monitor or the Server reports a fatal
error.
