DISPLAY TEST
From the main menu, press keys “D” and “T” (Display Test)
simultaneously for at least 3 seconds. The display will show the
following message for approximately one second:
A display pattern will then appear:
This pattern is used to check that all display characters operate
correctly. Examine the pattern carefully. To return to the main menu,
press any key on the programming keypad, or press the call button “C”
on the directory.
ERROR MESSAGES
Error messages may appear on the display in the event of directory
malfunction. Being able to interpret these messages correctly can be
extremely useful in pinpointing the cause of the problem.
IF AN ERROR MESSAGE IS SHOWN ON THE DISPLAY, TAKE
CAREFUL NOTE AND INFORM THE NEAREST SERVICE CENTER
OF ITS EXACT CONTENTS.
ERRORS DURING INITIALIZATION
The fi rst time a directory with a new EEPROM is turned on, the
program will test the memory to check that it operates correctly. As the
EEPROM is new, the program uses English as the default language,
even if the directory must later be set up for another operating
language. All messages displayed at this stage will thus be in English.
The fi rst message to appear will be:
This message indicates that the EEPROM test is in progress. The
number “xx” will increase progressively to indicate the percentage of
the test that has been completed.
The following message will appear if the EEPROM is missing or is
incorrectly installed:
If a read/write discrepancy is detected (i.e., because of an EEPROM
defect), the display will show:
Here, “xxxx” is the address (in hexadecimal format), “yy” is the written
data (in hexadecimal format) and “zz” is the read data (in hexadecimal
format).
ERRORS WHEN DELETING ALL DATA
Error messages may also appear when deleting all names from the
memory (see above). If the EEPROM is missing or is incorrectly
installed, the display will show:
If a read/write discrepancy is detected (i.e., because of an EEPROM
defect), the display will show:
Here, “xxxx” is the address (in hexadecimal format), “yy” is the written
data (in hexadecimal format) and “zz” is the read data (in hexadecimal
format).
DISPLAY CONTRAST ADJUSTMENT
Display contrast can be adjusted by means of a potentiometer
located at the rear of the directory and accessible from the exterior.
Display contrast is set to an optimal level during URMET DOMUS
inspection. For certain installations, however, small corrections may
be necessary.
