OPERATIONAL CHARACTERISTICS / DIFFERENCES:
1. IMPRES batteries may be charged in conventional chargers. 
However, in order for the Smart Energy features to be enabled, 
IMPRES batteries must be charged in the IMPRES Adaptive 
Multi-Unit Charger. The first time an IMPRES battery is charged in 
an IMPRES Adaptive Multi-Unit Charger, the charger initially 
indicates a STEADY YELLOW on the charger indicator. This first 
charge must be allowed to complete to a STEADY GREEN 
indication on the charger indicator. This properly calibrates the 
IMPRES battery and enables the Smart Energy features. If this 
process is interrupted, the charger will calibrate the battery upon 
the next insertion.
2. Since the IMPRES Adaptive Multi-Unit Charger automatically 
determines the conditions necessary to recondition an IMPRES 
battery, the charger may go into recondition mode when a radio or 
battery is inserted. This is indicated by a STEADY YELLOW on the 
charger indicator. The recondition mode can be over ridden, if 
required, by removing and reinserting the radio or battery. (Please 
see instructions later in this guide.)
3. The IMPRES Adaptive Multi-Unit Charger is designed to charge 
any battery listed in Tables 1 through 8. However, only genuine 
IMPRES batteries will provide Smart Energy features.
4. The IMPRES Adaptive Multi-Unit Charger must be used to calibrate 
IMPRES Smart batteries to ensure they accurately record, store 
and display IMPRES battery usage data.
