This is a class A equipment. In a domestic environment this product may cause radio interference in which case the user may be required  to take adequate measures.

Power Sources

Only Motorola Solutions authorized line cords listed in Table 2 should be used with the Multi-Unit Charger.

Table 2. Authorized Line Cords

DESCRIPTION

The Multi-Unit Charger comprises of a base unit which accommodates six charging locations. Each charging location is fitted with a charging pocket. The kit contains:

• 1 Multi-Unit Charger Base unit
• 6 Radio pockets or 6 Battery pockets *
• 1 Regional line cord
• 1 User Guide

To mix and match battery and radio charging, individual charging pockets have to be ordered separately from your local Motorola Solutions dealer to retrofit the Multi-Unit Charger. See Table 1 for approved charging pocket part numbers.

OPERATING INSTRUCTIONS

The Multi-Unit Charger will charge only Motorola Solutions authorized radios and batteries listed in Table 1. Prior to operating the charger, check that all radio and battery inserts are in place and properly latched.
The Multi-Unit Charger can charge up to six radios or batteries (in any combination) listed in Table 1.
Note: Prior to charging a battery with radio, turn the radio off.

Setting Up the Charger:

1. Install the desired combination of radio or battery pockets securely into the six available locations on the charger. To install, place the tabs on the bottom of the pocket into the slots on the charger base and press the top of the pocket into the latch until a positive click is heard and felt. Any combination of six pockets may be selected and installed.
   Note: To ensure proper installation, press the latch down into position to seat the insert into the MUC base, make sure all six locations have pockets installed. Attempting to use the charger with missing pockets will allow foreign objects to cause the charger to malfunction.

2. Plug the line cord into the rear of the Multi-Unit Charger and the plug into an appropriate AC outlet. The charger performs a quick power-up routine during which the LED indicators of each of the six charger pockets will flash once to indicate a successful power-up of that pocket.
   Note: The cooling fan begins running when the unit is plugged in and will remain running while the **unit is powered.

For Radio Charging:**

3. Insert a radio with battery (radio turned off) into the charger pocket and press down firmly until the connector on the bottom of the radio is mated to the connector on the charger. You will feel a slight snap when connection is made. Once the radio is properly engaged, the pocket LED illuminates. After 15 seconds, the LED will indicate that charging has started. To remove the radio after charging, hold down on the charger base and lift the radio straight up out of the pocket. The connector will automatically release.
   Note: To ensure the radio is properly charged, make sure the radio is inserted into the plug by firmly pushing down the radio into the base.
   General Limitations:
   

   • Radio will not start in Charge Mode (no charging) if the radio is OFF and battery voltage is above 4.1 V
     

   • **Radio will not start in Charge Mode (but trickle charging will run in the background) if the radio is OFF and battery voltage is below 3.4 V

For Battery Only Charging:

**

4. Insert a battery into the battery pocket by placing the top of the battery into the pocket and engage the holding features in the pocket. Press down on the bottom of the battery to engage the latch. After 15 seconds, the LED will indicate that charging has started. To remove the battery after charging, hold down on the charger base and lift the battery up via its top latch.

LED Indicator Status

When the radios and batteries are properly seated in the pockets, the charger LED will light to indicate the charging status as shown below:

Charger Status

(Radio and/or Battery)| Indicator
Power On| Single Blink Green
Rapid Charging| Steady Red
Top-off Charging| Blinking Green
Charge Complete| Steady Green
Battery Not Chargeable| Blinking Red
Waiting to Charge (Either the battery temperature is too hot or too cold, or battery voltage is too low or too high to allow Rapid Charging)| Blinking Orange

Optional Equipment

A wall mount bracket (part number: NNTN6844) or charger base tray (part number: NNTN7560) is available for the Multi-Unit Charger. Contact your local dealer to order this item. Installation is shown in the following image.

Mounting Multi-Unit Charger to Wall Bracket

1. Mount bracket to wall using appropriate fasteners in four locations (fasteners not included in kit).
2. Install two M4x25 screws (included in kit) through bracket into charger base as shown. Do not over tighten the screws.

Mounting Multi-Unit Charger to Charger Base Tray

1. Mounting holes are available at the back of Charger Base Tray for direct mounting to wall surfaces.

2. Position the base tray in the desired position and mount the base tray to wall using appropriate fasteners in four locations (fasteners not included in kit).
   
   Note: The Charger Base Tray can also be mounted with the Wall Mount Bracket (NNTN6844).

3. Pull out the locking plates at the two sides to align with the charger’s base screw holes.

4. Assemble two pieces of M4 screws (included in the package through the locking plates into the charger base as shown in the picture below. Do not overtighten the screws.

TROUBLESHOOTING

1. Verify no foreign objects or debris under charging pocket or in contacts.
2. Ensure charging pocket is properly latched into the charger base.
3. Verify radio or battery is properly inserted into pocket.

LED status changes unexpectedly or is inconsistent|

1. Charger function and LED status may appear inconsistent if a radio is operated in or near the charger. Discontinue use of the radio. The charger will automatically resume proper operation.

Charge time appears longer than usual|

1. Ensure all radios are turned off.
2. Normal charge times for lithium ion batteries are 3 to 8 hours, depending on battery capacity.

Radio or battery is not charged|

1. Radio or battery is not seated properly into pocket. Reinstall and verify charge status 15 seconds after insertion into charger.
2. Ensure radio is turned off.
