Operation and Maintenance Guide, v. 1.5
If the card is Invalid:
 The meter will display a message indicating a card error and to pay using coins (for
example, “Card Error, Use Coins”).
 If the card is left in the card reader device after the meter has displayed this
message, the meter will in almost all cases display a “Coins Only” message until the
card has been removed.
If the card is Valid:
 The meter takes a count of how much stored value is on the card. As money is
removed from the card, the token count value becomes smaller.
 If the user would simply like to check the balance of his or her card, removal of the
card can take place after the balance is displayed, and no value is deducted from the
card.
 If there are tokens remaining on the card, and the card is left in the meter after the
card balance has been displayed, the meter will attempt to initiate a purchase cycle.
Token Card Purchase Cycle
 If there is no time on the meter or it is in an overtime period (grace or penalty period), the
appropriate amount of time is added from zero and shown on the display. Several token
extractions may be required to complete a minimum purchase (if defined in the meter rate
profile) before time is displayed.
 If, for example the inserted card was to result in a purchase of 20 minutes of time, the
meter’s display would register 0:20, indicating zero hours, and twenty minutes of
countdown time remaining. The internal timer counts down for each minute shown on the
display. The meter display is decreased by one minute every time the internal timer
passes zero.
 If there is time on the meter, the appropriate amount of time for each token is added to
the time shown on the display up to the meter’s maximum time and this new time is
displayed. If the meter has a scheduled OFF (low power) period immediately following
the regular enforced time, the meter will only display the purchased time up to the next
scheduled OFF period (e.g. if the enforced period which ends at 6:00pm, is followed by
an OFF (low power) period, and the user inserts a card into the meter at 5:45pm, the
most time that the meter can display (or the user can purchase) is 15 minutes).
 If the Solo is on, but is functioning in a non-enforcement period (e.g. one hour before
enforcement begins), and a card is inserted to make a purchase, the time remaining
between the time of purchase and the enforcement period is automatically added to the
desired purchase time at no cost to the end user. For example, if enforcement begins at
9:00am, and a customer wishes to purchase one hour of time (value of $1.00) at 8:15am,
insertion of a card (after validation and display of the card balance) would result in the
starting time of 0:45, then permitting the user to continue purchasing time up until the
desired purchase has been made, resulting in a display of 1:45. Alternatively, the user
