3.6 Message Display

This section describes error messages displayed in the error status and user mes-

sages.

the Access Window and a corresponding error code is displayed in the middle line.

• While "Error" and an error code are displayed, a red backlight is flashing.

cleared at the same time).

• If two or more errors occur at the same time, the corresponding error codes are

displayed one by one each time a key is pressed. (Up to 16 error codes can be

stored at a time.)
