An intrinsic safety approach is provided for a battery powered communication device. Sparking is prevented at radio contacts during attachment and removal of a battery (104, 204, 304, 404) from a radio (102, 202, 302, 402) through the use of switches (112, 212, 312, 412/424) to isolate the radio capacitors from the radio contacts and/or dissipate energy from the radio capacitor through a discharge resistor (214, 314, 414). |
