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.

For the  basic system, there are  five  cables, one  power (P/N  512002 –  16 
Feet,  or  512001  –  35  Feet)  and  4  cameras  (P/N  510993  or  any  different  length 
cable). For external record indication and alarm/event marking, the record indicator 
/ event mark button harness (P/N 511986) is available (shown in Figure 12 on Page
