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
• the charger,

• the radio using the battery
1 To reduce risk of injury, charge only the 
rechargeable Motorola Solutions-authorized 
batteries. Other batteries may explode, 
causing personal injury and 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 and electric shock. If an extension 
cord must be used, make sure that the cord 
size is 18AWG for lengths up to 6.5 feet (2.0 
m), and 16AWG for lengths up to 9.8 feet 
(3.0 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.

repairable and replacement parts are not 
available. Disassembly of the charger may 
result in risk of electrical shock or fire.

charger from the AC outlet before attempting 
any maintenance or cleaning.
