Low battery monitor & battery saver circuit : How it works -
The BSC battery monitor works by manipulating the pulse rate characteristics after a given period of time in order to extend the life of the batteries . When (every time) the transmitter is switched on, the BSC (Battery Saving Circuit) starts to count in real time. When this count reaches twelve hours the BSC routine comes into play and slows down the pulsed signal interval to a battery saving level, this results in more power for longer and ultimately more tracking time.
Low battery monitor works in conjunction with the BSC but also monitors battery voltage. This triggers when approximately 80% of the batteries useful life has expired. When the transmitter trips into low battery mode, it latches and remains so until switched off. When the transmitter is switched back on, it may run as normal for a short while due to the batteries recovering slightly, but will soon trigger again. Low battery mode is announced by a slowing down of the pulsed signal interval (again to conserve remaining battery reserves) in conjunction with a transmitted double blip on every fifth pulse. Remember this monitor signals the end of the batteries useful life & should not be used as a reminder to change the batteries. Always check batteries after use as well as before with a "resistance" battery tester. See our battery tester page for more details.
