3.3 Changing Power Sources
The controller will tell you when to change a battery through three indicators:1
1 Battery indicator will show 1 yellow light.
2 Alarm indicator will be solid yellow.
3 Display will read [Low Battery] [Replace Battery].
Changing from Two Batteries to a Battery and AC/DC Adapter
1. Plug the AC adapter into an electrical outlet or the DC adapter into a power
port found in most cars.
2. Disconnect the battery with the least remaining charge.
3. Connect AC or DC adapter.
Proper connection is veried when the AC/DC Indicator on the controller turns
green and the corresponding Battery Indicator turns off. If the AC/DC Indicator
doesn’t turn green, the controller is using battery power and the [Power
Disconnect] alarm will sound.
Changing from an AC/DC Adapter and Battery to Two Batteries
Before switching from AC or DC power to battery power, make sure that a fully
charged battery is available. Connect the fully charged battery after disconnecting
the AC or DC adapter.
