IMPORTANT
SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This document contains important safety and operating instructions.
Please read these instructions carefully and save them for future
reference.
Before using the battery charger, read all the instructions and
cautionary markings on (1) the charger, (2) the battery, and (3) the
radio using the battery.
1. To reduce risk of injury, charge only the rechargeable
Motorola authorized batteries listed in Table 4. Other
batteries may explode, causing personal injury and
damage.
2. Use of accessories not recommended by Motorola
may result in risk of fire, electric shock, or injury.
3. To reduce risk of damage to the electric plug and cord, pull by the
plug rather than the cord when disconnecting the charger.
4. An extension cord should not be used unless absolutely
necessary. Use of an improper extension cord could result in risk
of fire and electric shock. If an extension cord must be used, make
sure that the cord size is 18 AWG for lengths of up to 100 feet
(30.48 m), and 16 AWG for lengths up to 150 feet (45.72 m).
5. To reduce risk of fire, electric shock, or injury, do not operate the
charger if it has been broken or damaged in any way.
6. Do not disassemble the charger – it is not repairable and
replacement parts are not available. Disassembly of the charger
may result in risk of electric shock or fire.
7. To reduce risk of electric shock, unplug the charger from the AC outlet
before cleaning.

Operational Safety Guidelines
• The radio can be in ON state only when the data is transmitted
wirelessly (i.e. via Wi-Fi). Otherwise, turn OFF the radio.
• This equipment is not suitable for outdoor use. Use only in dry
locations/conditions.
• Connect equipment only to an appropriately fused and wired supply
of the correct voltage (as specified on the product).
• Disconnect from line voltage by removing the main plug from the
outlet.
• The socket outlet to which this equipment is connected should be
close and easily accessible.
• Maximum ambient temperature around the charger must not exceed
40 °C (104 °F).
• Make sure the cord is located where it will not be stepped on, tripped
over, or subjected to water, damage, or stress.
• Output power from power supply unit must not exceed the ratings
stated on the product label located on the bottom of the charger.
Operating Instructions
The IMPRES Adaptive Charger System is a fully automated battery
care system. All a user needs to do is follow these simple steps:
1. Place the radio / IMPRES battery into the charger.
2. Remove the radio / IMPRES battery when it's fully charged (LED
turns steady GREEN).
The charger pocket accommodates either a radio with an IMPRES
battery attached or an IMPRES battery alone. Prior to charging a
radio with an IMPRES battery, radio can be in the ON state only
when the radio is transmitting data wirelessly. Otherwise, turn
OFF the radio. Batteries charge best at room temperature.
Additionally, the charger is equipped with 2-USB Type A Power
Outputs that facilitates the charging of two wireless device by a
constant 2.5 W of power ( 5 V at 500 mA) per connector.

Charging Procedure
1. Plug the charger end of the power supply cord into the power
receptacle located at the back of the charger.
2. 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 Green Blink on the charger indicator.
3. Insert an IMPRES battery, or a radio with an IMPRES battery (radio
can be in the ON state only when the radio is transmitting data
wirelessly. Otherwise, turn OFF the radio), into the charger
pocket by:
a. Aligning battery contacts with the charger contacts.
b. Pressing the battery into the pocket, ensuring complete contact
between charger and battery contacts.
4. To remove a radio or IMPRES battery from the charger, pull straight
up until the battery completely clears the charger housing.

1. Programming Port - program the charger.
2. Dual USB ports - power source to wireless accessories and fleet
management.
3. DC inlet - connect to power supply.
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.

Initialization
In order for the features of Motorola IMPRES batteries and the
Adaptive Charging System to be fully available, the data contained in
Motorola 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 or more
to complete the process. Do not remove the battery from the charger
until the Steady Green light is on.
Automatic Reconditioning
The Motorola IMPRES Adaptive Charger, when used in conjunction
with a Motorola IMPRES battery, has the ability to determine when it is
appropriate to recondition the battery (see IMPRES Feature/Benefit
Description section for complete list of IMPRES benefits).
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 or more 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.
Reconditioning Switch
The charger is equipped with a switch on the bottom of the unit that
can be utilized to manually terminate the reconditioning process (as a
systemic, on-going use-case). However, the charger will continue to
provide an indication that the battery needs to be reconditioned.

English
Switch the RECONDITION to “ON” located at the bottom of the charger
to enable the recondition feature.
Manually Terminating the Reconditioning Process
At any time during the reconditioning process of a Motorola 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
The IMPRES Adaptive Charger incorporates the features of:
• A universal input power supply

English
• A constant current rapid charger
• A negative pulse conditioning charger
• A reconditioning unit
• A 2-USB Type A Power Outputs
• A user selectable on/off switch for turning ON/OFF reconditioning.
The combination of the features listed above are unique in a desktop
charger. Therefore, operation of the radio with a battery attached while
in the charger is not recommended.
During the charging process, radio operation may result in minimally
reduced radio performance and extended battery charge time.
During the reconditioning process, the battery becomes fully
discharged. As a result, the radio may shut down during reconditioning
mode.
When troubleshooting, always observe the color of the LED.
