Listed below are the different Light Emitting Diode (LED) indicators and switches found on this device and their respective functions:

Front Panel

On A/C (Green, stable) - lights up solid when the RG Battery Backup is operating on A/C power.
Testing Battery (Green, flashing) - flashes when the RG Battery Backup is conducting a self-test. The LED will behave as described if the self-test is initiated manually and periodically thereafter. A self-test procedure will approximately last for five (5) minutes.
On Battery (Yellow, stable) - lights up solid when the RG Battery Backup is operating on battery power. You will hear an alarm tone every 10 seconds but this will automatically shut OFF once A/C power is restored.
Low Battery (Yellow, flashing) - flashes when the battery power is running low. There will be an alarm tone every second until the unit performs a forced shutdown when the battery power is depleted.
Replace Battery (Red, flashing) - may indicate that the battery needs to be replaced immediately. There will be an alarm tone every five (5) seconds when this occurs. You can conduct a self test by observing the alarm tone. If it persists, replace the battery as soon as possible to ensure the proper operation of the RG Battery Backup.
Fault (Red, stable) - lights up solid when a fault takes place. There will be a continuous beep when this occurs. To resolve this, you can reset the unit by powering OFF the unit, disconnecting it from the power outlet then reconnecting it after a few minutes then turning ON the unit again.
Mute switch - used to enable or disable the Mute function of the alarm tone. The alarm tones will be disabled if the switch is set to ON.
