Using the Keypad
Dispense Coins / Empty Tubes
Press a button once to dispense a coin from a
corresponding tube. If you press and hold for more
than three seconds, coins are dispensed
automatically until only a sufficient minimum (the
safe count) are left to operate the dispense
mechanism. To empty a tube or a cassette, you
may have to take out the last coins by hand.
Float-Up Tube Counts Automatically
Press the buttons, then feed tube coins through the
acceptor to refill the tubes to their pre-set float
level. When float levels are reached, further coins
are rejected. If automatic float is left by pressing B,
tube counts re-set to pre-programmed float levels.
Re-set the Tube Counts
Press the buttons to force tube counts to re-set to
pre-set float levels. If there are not enough tube
coins to meet the pre-set levels, coin counts remain
incorrect until recalibration takes place. ★If an
audit FEM is fitted, reset via Mode+A+Bis not
available.
Automatic Float Down to Pre-set Levels
If the unit is programmed for this function,
press the buttons to dispense coins until tube
counts reach their pre-set float levels. If the
numbers of coins already in the tubes are equal to
or below the float levels, no coins are dispensed.
Set the Vend Prices
Press the buttons. Insert coins equal to the lowest
price. Make a selection. A 45-second time-out
starts after each coin. More selections at the same
price can be made without inserting extra coins.
Add coins for the next highest price, and make a
selection. Continue until all prices are set. Press C
to cancel credit and to exit price teach.
