Long Term Storage
Although the Digital BUS-WATCH® systems draw very little current in the
stand-by mode, if the systems are installed but not used for an extended period of time
(longer than 2 weeks) it is recommended that the power be disconnected from the
DVR to avoid draining the vehicle battery. The DVR internal clock will hold time and
date for up to 10 years sitting on a shelf, and the daylight saving time functions will
kick in upon re-initialization when power is applied.
