Power On Self Test (POST)
Power On Self Test
The Phoenix POST is used as standard. This checks the functioning of the
standard PC AT components on the motherboard. To enable it to test
POS-specific functions, relevant function tests have been added to the
Phoenix POST.
The error messages are output on the cashier display, the external cashier
display or the VGA monitor. The cashier display and the monitor have a
high priority, but if a VGA adapter is plugged in, the messages always ap-
pear on the monitor. Error messages only appear on the external cashier
display when there is no monitor or standard cashier display.
The messages are output on the cashier display in the following format:
TEST POS TEST TYPE ERROR NUMBER
Error text
Here is an example of an error message on the cashier display:
TEST POS MC 02
BATTERY EMPTY
ANY KEY TO RETRY
In the Power On Self Test, static errors are reliably locali-
zed, whereas sporadically occuring errors are determined
only to a limited extent.
If the POST indicates that there is an error, contact your technician or cu-
stomer service. You will find a list of the POST error messages in the ap-
pendix.
