Extending battery shift life
Battery shift life can be extended by activating
economy mode (conventional radios) or by
using dynamic power control (trunked
radios).
During economy mode, the radio cycles
between the normal receive state and a stand-
by state, in which some of the radio’s circuitry
is switched off or placed on standby mode.
Dynamic power control optimises the radio’s
power use by reducing the transmit power in
high signal strength areas.
Typical drain rates for a conventional UHF
radio 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 cycling
enabled; and
■ 40 mA with high economy cycling
enabled.
Economy cycling in conventional radios is
programmed in the Power Save Features
screen of the Tait Orca Portable Conventional
Programming Application (TOPCPA). Dynamic
power control in trunked radios is enabled in
the User Selectable Parameters screen of
the Tait Orca Portable Trunked Programming
Application (TOPTPA).
Disposing of used nickel-cadmium
batteries
NiCd batteries contain a small amount of the
metal cadmium, which can produce potential-
ly toxic waste if not disposed of properly.
Contact your Tait dealer for recycling details.
