Key 0: NOT USED
No function is allocated to key 0 when the meter is operating in Prepayment mode. A short press of this key will
display 'Not Used' as shown below:
8.3 Diagnostic Displays in Default Mode
In this mode keys 3, 7, 8, 9 and 0 are not assigned with any functions hence will display 'NOT USED'. All other
keys have the same function as in 'Credit Mode' (see Section 8.1 Diagnostic Displays in Credit Mode).
