Understanding LED indicator status lights and information

Battery Indicator (when checking battery status)

Color	Indicates
Green	70% or more of full charge
Yellow	20% to 70% of full charge
Red	20% or less (charging needed). If the battery LED is flashing red when not checking the battery, see Battery light is quickly blinking red

Battery Indicator (while charging)

Color	Indicates	Details
Yellow	Battery is Charging	The color of the LED will remain yellow until the battery reaches 100%. Once at 100% the LED will turn off (not turn green) and the system will stop charging so there is no risk of overcharging.
Off	Charging Cycle Done	Once the battery reaches 100% the system will stop charging and the LED will turn off. If the system remains connected to AC power and the battery drains to about 80% charge the system will start to charge the battery again (yellow LED will turn back on). This helps preserve battery life by minimizing charge cycles and will continue until AC is disconnected.

Battery Indicator (when in use)

Color	Pattern	Indicates
Yellow	Very Fast Flash (4 times second)	System thinks battery temperature is outside of -20°C to +65°C range and has disabled all functionality for safety/reliability reasons.
Yellow	Fast Flash (2 times second)	The battery is in pre-charge mode (will stop and go solid after a short time) or that the battery pack is either too hot or cold to charge (outside 0°C - 45°C).

Bluetooth® LED State	Description	Indicates
Off		Wireless source is not selected
On		Wireless source is connected
Fast Flashing	Flashes on and off twice every second	Wireless source is connecting
Slow Flashing	Flashes on and off once every three seconds	Wireless source is not connected and system is available to connect to a previously paired device
Slow Pulsing	Fades on and off once every second	System is in discovery mode and waiting for a signal

To check the battery status, see Checking the remaining battery charge

If all three white LEDs are lit at the same time see, All LEDs are lit at the same time

If the battery LED is flashing red when not checking the battery, see Battery light is quickly blinking red

If the battery LED is solid red all the time, see Battery light is always red

If the battery LED is solid yellow for longer than 10 hours while charging, see Battery LED is solid yellow after charging for an extended period of time
