Digital BUS-WATCH
®
R1001 / R4001
In order to prevent the possibility of hard-drive damage during
cold periods, the Digital BUS-WATCH® is equipped with a
temperature sensor. The heater is activated when the temperature is
below 40° F and the Digital BUS-WATCH® is turned on via system
switch or timer. The red LED labeled HTR on the front panel indicates
this. The colder the temperature, the longer the heater remains on, with
a maximum of fifteen minutes at the coldest temperatures. When the
unit has completed its heating cycle, it will restart and operate
normally. As the temperature inside the unit drops during operation,
the heater will periodically come on to maintain a working operating
temperature. The unit can operate to temperatures below -40° F. The
menus and the Installers Mode are still operational during the Initial
Drive Warming Period.
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.
