IMPORTANT SAFETY INSTRUCTIONS

This document contains important safety and operating instructions. 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) on the radio using the battery.

WARNINGS

  1. To reduce risk of injury, charge only the rechargeable Motorola Solutions-authorized batteries listed in Table 1. Other batteries may explode, causing personal injury or damage.
  2. Use of accessories not recommended by Motorola Solutions 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 or electric shock. If an extension cord must be used, make sure that the cord size is 18 AWG for lengths 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. Take it to a qualified Motorola Solutions service representative.
  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 electrical shock or fire.
  7. To reduce risk of electric shock, unplug the charger from the AC outlet before attempting any maintenance or cleaning.
  8. To reduce risk of injury, use charger with Motorola Solutionsauthorized power supplies listed in Table 2.
  9. This is a Class A product. In a domestic environment, this product may cause radio interference in which case the user may be required to take adequate measures.

OPERATIONAL SAFETY GUIDELINES

  • 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 main plug.
  • The socket outlet to which this equipment is connected should be close by and easily accessible.
  • In equipment using fuses, replacements must comply with the type and rating specified in the equipment instructions.
  • Maximum ambient temperature around the power supply equipment must not exceed 40 °C (104 °F).
  • Output power from the power supply unit must not exceed the ratings stated on the product label located at the bottom of the charger.
  • Make sure the cord is located where it will not be stepped on, tripped over, or subjected to water, damage, or stress.

BRIEF DESCRIPTION

The Dual-Unit Charger is intended for use with the Motorola Solutions-approved Lithium-Ion rechargeable batteries (listed in Table 1). The front pocket of the charger is capable of handling a radio with an attached battery. The rear pocket is designed only to charge the batteries (alone).

An illuminated LED indicates the state of charge for the rear pocket; charge status in the front pocket is indicated by the radio display.

The Dual-Unit Charger supports data pass (from the radio to a PC) through the use of the SKN6371C USB Cable (note: USB Data Cable supplied separately).

OPERATIONAL GUIDELINES

  • Always remember to power the Dual-Unit Charger first before inserting the radio handset with the attached battery into the front pocket or the auxiliary battery into the charger’s rear pocket.
  • Use the Data Cable for data ONLY. The data cable will not support battery charging.
  • The front pocket has charging priority over the rear pocket. Therefore, the handset in the front pocket may completely charge its battery before the battery in the rear pocket begins charging.

OPERATING INSTRUCTIONS

Dual-Unit Chargers are intended for use only with the authorized Motorola Solutions batteries and power supplies listed in Table 1 and Table 2 on pages 6 and 7; usage with unauthorized products may prevent proper operation.

The battery charger will accommodate a radio with an attached battery in the front pocket, and a battery alone in the rear pocket. To charge a battery, use the following procedure: (Refer to Figure 1 on page 12).

  1. Plug the round end of the power supply cord into the DC Connector at the back of the charger.
  2. Plug the power supply into the appropriate AC outlet. The charger LED will blink green once to indicate a successful power-up.
  3. Insert a radio with battery, into the charger’s front pocket by:
    a. aligning the groove on each side of the radio with the corresponding raised rail on each side of the charger pocket.
    b. sliding the radio into the charger pocket, ensuring complete contact between the charger and radio contacts.
  4. When the radio is properly seated in the pocket, the radio display will illuminate and display the charge status.
    Note: Charge new batteries overnight to ensure full charge. To minimize charge time, it is recommended to turn the radio OFF.
  5. Insert a battery into the charger’s rear pocket by: a. aligning the slot on each side of the battery with the corresponding raised rail on each side of the charger pocket. b. sliding the battery into the charger pocket, ensuring complete contact between the charger and battery contacts.
  6. When the battery is properly seated in the pocket, the charger LED will light in accordance with Table 3 on pages 13­14.
    Note: Charge new batteries overnight to ensure full charge.

TROUBLESHOOTING

When troubleshooting, always observe the color of the LED:

(LED is for Rear Pocket ONLY. Charge indications for the battery attached to a radio is indicated from the radio display)

Table 3: Rear Pocket Battery/Charger Status

LED Color Battery/Charger Status
No LED indication The Battery Pocket is empty.
Or, the Battery is not fully seated into the Charger Battery Pocket or something is preventing the Charger from detecting the Battery.
Single green blink Successful charger power-up.
Blinking red The Charger identifies the Battery as invalid, damaged or over-charged.
The Charger may have detected an open or shorted Battery contact, corrupted Battery data, an invalid Motorola Solutions identifier from the Battery memory device, no Battery memory device.
Steady red The Charger successfully detects a Battery in the Battery Pocket.
The Charger is charging the Battery.
The Battery is 0–90% charged.
Blinking orange The Charger successfully detects a Battery in the Battery Pocket.
The Charger is Waiting to Charge the Battery.
Note: The wait may be because the Battery is too hot, too cold, over-discharged, or temporarily gave charge priority to the radio. After the Battery temperature changes to an acceptable value or the Charger recovers the Battery from the over-discharged condition, then the Charger will transition to the appropriate charging mode.
Blinking green The Charger successfully detects a Battery in the Pocket.
The Charger is charging the Battery. The Lithium battery is more than 90% charged.
Steady green The Charger successfully detects a Battery in the Pocket.
Lithium battery charging is more than 95% complete.

No LED Indication?

  1. Make sure that the power supply cable is plugged securely into the DC Connector and that the power supply is plugged into an appropriate AC outlet.
    a. Unplug the power supply from the wall. Inspect the electrical contacts on the power supply plug.
    b. Unplug the power supply from the charger. Inspect the electrical contacts on the power supply cable and the charger DC connector.
    c. Firmly reattach the power supply to the charger.
    d. Firmly replug the power supply into the appropriate AC outlet.
  2. Remove the Battery from the Charger Pocket:
    a. Inspect the electrical contacts on the Battery.
    b. Inspect the electrical contacts in the Charger Pocket.
    c. Firmly reinsert the Battery into the Charger Pocket.

Blinking Red LED Indicator?

  1. Remove the Battery from the Charger Pocket.
    a. Verify that the Battery is a Motorola Solutions Battery listed in Table 1 on page 6.
    b. Inspect the electrical contacts on the Battery.
    c. Inspect the electrical contacts in the Charger Pocket.
    d. Firmly reinsert the Motorola Solutions Battery into the Charger Pocket.
    e. If the indication persists, contact Motorola Solutions representative.

Blinking Orange LED Indicator?

Wait. The Battery temperature will recover to the allowable range for resumption of charging. Or, the charger will recover the Battery from the over-discharged condition.

Note: Charging outside of the stated temperature and voltage limits can drastically reduce the life expectancy of the battery. When the battery charger detects the proper battery conditions, charging begins automatically (steady red LED).

SERVICE
