Installing Batteries
The BS004 radio operates with either 4 AAA Alkaline Batteries or optional NiMH battery. The belt clip

1. With the back of the radio facing you, remove the Battery Cover by sliding it down from the unit.
2. Insert 4 AAA batteries observing the polarity as shown, or install the optional battery. Installing the
batteries incorrectly will prevent the unit from operating or can damage the unit.
