2.3.4 LCD display mode
There are 5 modes of LCD display:
Auto-scrolling display
Meters’ default display mode is the Auto-scrolling display. This will cycle to the next
screen automatically every certain second (configurable). The auto-scroll display table is
configurable with up to a maximum of 32 display items; refer to the table in item 2.3.7.
On request display via push button
During the Auto-scrolling display mode, the meter will switch to the on-request display
mode after push the enquiry button. Under the on-request display, the button may be
used to cycle through to the various display screens. Should the button not be pressed
after duration of 30 seconds, the meter will resume the Auto-scrolling display mode. The
on-request display table is configurable with up to a maximum of 32 display items; refer to
the table in item 2.3.7.
Key-in display mode
When the user presses any key, the LCD will display the key value. The display will switch
back automatically if there is no further key operation in a given reasonable time. If a
short code or active token is entered correctly and followed by the Enter key the LCD will
display the corresponding information and will switch back to previous display after 10
seconds.
Power off display
When powered off the meter will display the credit balance remaining.
Meter error display
Should the meter detect memory error or some other damage it would stop auto-scrolling
and display the word ‘Error’.
