Entering tokens via the keypad
Tokens such as credit, set power limit and tamper reset, are entered into the meter by keying in the
numbers printed on the token via the keypad. The numbers entered are displayed on the LCD as they
are being entered and scroll from right to left, with a decimal point displayed at every fourth digit for
ease of viewing.
Visual feedback is provided by flashing the happy face icon with each key press.
Audible feedback is provided by a „beep‟ on each key press.
Incorrect entries can be corrected with the backspace key, which removes the rightmost digit on the
LCD with each key press. Two backspace key presses in quick succession will clear the entire entry.
Acceptance of a valid token is automatic. Once a complete token has been entered, the meter
processes it and, depending on the result, displays one of the sequences described in
– refer section
7.2. Again, depending on what sequence is invoked, the keypad could remain locked for a variable
period of time i.e. it will not respond in any way to further key presses.
An incomplete token entry will be timed-out after 30 seconds; where after the customer interface unit
reverts to normal operation.
