b. Turn system lights on
Pressing the TEST button will turn the system lights on to verify cor-
rect installation or for troubleshooting a system problem. The lights
will be turned on anytime (day or night) for 5 minute intervals.
The lights can be turned on repeatedly with the TEST button
except when the system is in LVD (load disconnect/red LED on).
In LVD the TEST button will only work 3 times to avoid damaging
the battery.
If pressing the TEST button causes a load disconnect (LVD), the
lights will turn off. Wait 5 minutes and press TEST again to turn
the lights on in LVD.
