BRIEF DESCRIPTION
The Dual-Unit Charger is intended for use with the Motorola Solutions approved Lithium-ion (Li-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 above mentioned batteries alone.
An illuminated LED indicates the state of charge for the rear pocket; charge status in the front pocket is communicated via the radio display.
The Dual-Unit Charger supports data pass (from the radio to a PC) through the
use of the mini-USB to 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.
