Chapter 2 Installation
Power Supply
The DPM uses a rechargeable Nickel-Metal Hydride
battery pack. Charge life is about 20 hours with the
Bird WPS, 50 hours with other sensors.
The DPM can use an external power source. Using the
DPM with the ac adapter or the 12V cigarette lighter
adapter will also charge the battery. Charging time
from full discharge is 8 hours using the ac adapter.
When using the cigarette lighter adapter, charge time
will depend on the car battery charge. When the exter-
nal adapter is connected, the battery level indicator
will blink until the battery is fully charged. When
using the internal batteries, the indicator will be on
continuously and the black bar will show the battery
change remaining.
 Note: For optimum battery life, only
charge the batteries after the battery level indi-
cator empties completely and begins to blink.
