1)
The Solo has a three square inch solid-state high contrast LCD on the back that is used
to indicate paid status, expired status, and failed status. The LCD uses a red polarizer,
which produces a high contrast, high visibility red color with a programmable variable
flash rate.
2)
The Solo can either statically display or flash the following information: "Out of Order",
"Expired", 2 x International "No Parking" icons, and a solid red display. When the Solo is
in normal operation and there is paid time remaining on the meter, the rear display will
appear blank with the LCD’s entire gray/silver background visible. When paid time has
expired, the word EXPIRED, in RED on the LCD’s gray/silver background will appear,
and depending on the factory profile settings, this message may alternate with the
reverse image equivalent, where the entire display is RED except for the word EXPIRED
which will show on the LCD’s gray/silver background.
3)
The Solo has five rear mounted LED indicators, a left Red/Green led pair and a right
Red/Green led pair as well as a single yellow LED. The normal configuration is to have
the left hand green LED flashing when the meter is “OK” or when in a valid “time
displayed” state. It flashes the left hand red LED when in a “No Parking” or “Meter
Expired” state and flashes the yellow LED to indicate to the service and maintenance
