“any of”
the
following initial conditions fails:
The oldest transaction in database shouldn’t be older than a configurable “Cardholder Retention
Time” Variable Object.

Battery and Charger Safety
Proper battery and charger safety is necessary to ensure the terminal will perform to its potential and
reduce the risk of overheating, igniting or explosion, resulting in serious bodily harm or property damage.
Do not disassemble, open, crush, bend, deform, puncture, shred or attempt to modify the battery or
charger.
Do not modify or remanufacture, attempt to insert foreign objects into the battery or charger, immerse
or expose to water or other liquids, or expose to fire, explosion, or other hazards.
Only use the battery and charger for the terminal for which it was specified.
Only use the battery with a charging system that has been qualified with the unit. Use of an
unqualified battery or charger may present a risk of fire, explosion, leakage or other hazard.
Do not short circuit a battery or allow metallic or conductive objects to contact the battery terminals.
