OPERATING INSTRUCTIONS
The IMPRES Adaptive Single-Unit Charger System is a fully automated battery care system. All a user needs to do is follow these simple steps:
- Place the radio / IMPRES battery into the charger.
- Remove the radio / IMPRES battery when it’s fully charged (LED turns steady GREEN).
The charger’s pocket accommodates either a radio with an IMPRES battery attached or an IMPRES battery alone. Prior to charging a radio with an IMPRES battery, turn the radio off. Batteries charge best at room temperature.
Charging Procedure
- Plug the charger end of the power supply cord into the power receptacle located at the back of the charger.
- Plug the wall receptacle end of the power supply cord into the appropriate AC outlet. A successful power-up sequence is indicated by a SINGLE BLINK GREEN on the charger indicator.
- Insert an IMPRES battery, or a radio with an IMPRES battery (with the radio turned off), into the charger’s pocket by:
- Aligning the groove on each side of the battery with the corresponding raised rail on each side of the charger pocket.
- Pressing the battery toward the rear of the pocket.
- Sliding the battery into the charger pocket, ensuring complete contact between the charger and batterycontacts.
- To remove a radio or IMPRES battery from the charger, use two hands to remove a radio or battery from the charger pocket – one hand to hold and support the charger, and the other hand to remove the radio or battery
Once the IMPRES battery is properly seated into the pocket, the charger indicator illuminates, indicating the charger has recognized the presence of the battery. Refer to the charging indicators in Table 1.
Table 1. IMPRES Battery Charging Indicators
| Charge Indicator | Description |
| Single Blink Green | Charger has successfully powered up. |
| Steady Red | Battery is in rapid charge mode. |
| Blinking Green | Battery has completed rapid charge (>90% available capacity). Battery is in Top-Off charge (Trickle charge). |
| Steady Green | Battery has completed charging and is fully charged. |
| Blinking Orange | Battery is recognized by charger but is waiting to charge. (Either the battery voltage is too low or the battery temperature is too low or too high to allow charging. When this condition is corrected, the battery will automatically begin charging.) |
| Blinking Red | Battery is unchargeable or not making proper contact. |
| Steady Orange | (This feature applies to IMPRES batteries only)
Battery is in recondition or initialization mode. The length of time the charger remains in this mode depends upon the state of charge remaining in the battery when inserted. (Fully charged batteries require more time to recondition – 8 to 12 hours or more – than fully discharged batteries.) |
| Blinking Red/Green | (This feature applies to IMPRES batteries only)
Battery has completed charging and is fully charged. Battery continues to be usable, but may be nearing the end of its rated service life. |
INITIALIZATION
In order for the features of Motorola Solutions IMPRES batteries and the Adaptive Charging System to be fully available, the data contained in Motorola Solutions IMPRES batteries must be initialized by the charger the first time it is charged. This process is indicated by a STEADY ORANGE light on the charger indicator (the same as if the battery were reconditioning). The process is automatic, includes an initial reconditioning of the battery, and begins charging upon completion of this process. This process requires time to initialize the battery, so the battery should be left in the charger for approximately 12 hours to complete the process. Do not remove the battery from the charger until the STEADY GREEN light is on.
AUTOMATIC RECONDITIONING
The Motorola Solutions IMPRES Adaptive Single-Unit Charger, when used in conjunction with a Motorola Solutions IMPRES battery, has the ability to determine when it is appropriate to recondition the battery (required to remove memory issues in IMPRES batteries). When an IMPRES battery is properly inserted into the charger, the charger determines if it is appropriate to recondition the battery. If the battery needs reconditioning, the charger automatically indicates a STEADY ORANGE.This process may take up to 12 hours to complete, depending upon the state of charge and capacity rating of the battery when it is inserted.It is important to note, for this process to be effective, the IMPRES battery must be allowed to complete the recondition/ recharge process. Leave the battery in the charger until the charger indicates a STEADY GREEN.At the completion of the recondition cycle, the charger automatically recharges the IMPRES battery.
Manually Terminating the Reconditioning Process
At any time during the reconditioning process of a Motorola Solutions IMPRES battery (STEADY ORANGE indication), reconditioning may be terminated by removing and reinserting the battery back into the charger within 5 seconds. This causes the charger to terminate the reconditioning process and begin the charging process. The charger indicator changes to a STEADY RED. The charger will attempt to recondition the battery at the next battery insertion.
Manually Initiating the Reconditioning Process
Within 2-1/2 minutes of the initial insertion of an IMPRES battery (STEADY RED indication), remove and reinsert the battery within 5 seconds to manually force reconditioning to occur. The charger indicator changes from a STEADY RED to a STEADY ORANGE. This forces the charger to recondition and automatically recharge the battery. This is a useful feature to have when IMPRES batteries have been in storage for several months or longer. Two or three manual recondition cycles may be required to rejuvenate the batteries, due to long term storage conditions.
TROUBLESHOOTING
When troubleshooting, always observe the color of the LED.
