RECEIVER SWITCHABLE BETWEEN NETWORK SUPPLY MODE AND POWER-CONSERVING BATTERY SUPPLY MODE |
摘要 |
A radio warning receiver has a battery or accumulator (7) and means (8) for switching over to battery operation mode when network power (6) fails. Battery power is conserved by turning off (9) power to the end stage (3), placing the warning receiver in a so-called Stand-By Mode, until a control signal is detected (5) which indicates that a warning is to be broadcast. Then, power to the end stage is restored (11) for the duration of the warning broadcast.
