# Understand Special Charging Indicator

#### Indicator Behavior:

When you connect the USB charger to your device, the charging indicator LED will initially flash red slowly. Following this, all four LEDs will flash simultaneously.

#### What This Means:

This specific pattern of flashing LEDs is an alert that the device's battery is excessively discharged.

#### Immediate Action Required:

To address this, continue charging the device using the adapter for a minimum of 5 minutes. This extended charging period is necessary to recover the battery from its overly discharged state.

#### Expected Outcome:

After charging for the recommended duration, your battery should return to a normal state, indicated by the standard charging LED behavior.

Note: Regularly allowing your battery to become overly discharged can affect its overall lifespan and performance. It is advisable to charge your device before the battery level becomes too low.
