E - 4 Battery packs June 2003 IPN: M5000-00-105Extending battery shift lifeBattery shift life can be extended by activatingeconomy mode (conventional radios) or byusing dynamic power control (trunkedradios).During economy mode, the radio cyclesbetween the normal receive state and a stand-by state, in which some of the radioís circuitryis switched off or placed on standby mode.Dynamic power control optimises the radioíspower use by reducing the transmit power inhigh signal strength areas.Typical drain rates for a conventional UHFradio are: 1.5 A at high power transmit; 300 mA in receive at rated audio; 80 mA on standby (no audio); 55 mA with low economy cycling enabled; 45 mA with medium economy cyclingenabled; and 40 mA with high economy cyclingenabled.Economy cycling in conventional radios isprogrammed in the Power Save Featuresscreen of the Tait Orca Portable ConventionalProgramming Application (TOPCPA). Dynamicpower control in trunked radios is enabled inthe User Selectable Parameters screen ofthe Tait Orca Portable Trunked ProgrammingApplication (TOPTPA).Disposing of used nickel-cadmiumbatteriesNiCd batteries contain a small amount of themetal cadmium, which can produce potential-ly toxic waste if not disposed of properly.Contact your Tait dealer for recycling details.
