The<unk>  was a combination voice and telemetry radio communications system used in the 1970s and '80s by paramedics to talk to the physicians supervising them from a hospital base station. The key difference between this unit and another two-way radio was that it had the ability to transmit a patient's electrocardiogram.<unk>  Model 3502; unit shown is identical to the one used on the television show Emergency! The<unk>  was produced by the Biocom Company. The<unk>  3502 used the internals of a General Electric PE series handheld radio mounted into an orange case, which was made of an orange laminated fiberglass with aluminum trim. The<unk>  had an internal rechargeable battery that powered the sensor equipment, the radio, and an amplifier that raised the transmitting power to 50 watts. The unit had a connector for a vehicle-mounted antenna allowing better signal reception and transmission from the back of an ambulance. The<unk>  could have any 6 (the maximum that could fit in the PE radio) of the 10 UHF "Medical" duplex channels in the 450-470 MHz range. This allowed flexibility in the overall system. The battery was a NiCad that could charge in only 15 minutes.
