CORE Attachment and Littmann CORE Battery Issues

Use this guide if your Littmann CORE or CORE Attachment won't charge or won't turn on.
 

What the light means

• Blinking white: on, not connected.
• Solid white: connected to the app.
• Solid orange: charging.
• Solid green: fully charged.
• Blinking orange: low battery.
• No light: off or no charge.
   

My device won't charge

1. Plug in the micro-USB cable. The light should turn solid orange (charging) and then solid green (full). 
2. No light? Try a different micro-USB cable—worn or thin cables are the most common cause.
3. Try a different USB wall charger, not a computer port.
4. A full charge takes about 3 hours and lasts about 8 hours of continuous use. Turning the device off between patients extends battery life.

My device won't turn on

1. Charge until the light is solid green.

2. Unplug and slide the power switch to ON—it sits flush with the volume buttons when on. The light should blink white. 

   

3. If nothing happens, press the volume + and – buttons quickly a few times.
4. Turn the switch off, wait 10 seconds, and turn it on again.
