Then, turn off the device by turning the power button on the bottom of the device to
the off position.
b) If an Error Occurs:
If an error occurs, the device will turn off the TTFields and make a loud beeping
noise. The red Error light will light up (as shown below).
To turn off the device:
1. Press the TTFields button on the front of the device to stop the notification
signal. The red Error light will turn off.
2. Turn off the device by turning the power button to the off position.
3. See the Troubleshooting Guide (Section 15) for instructions on fixing
problems. Restart the device and restart treatment if no problem is found. If
the notification signal does not stop, contact technical support (Section 16).
c) When the Low Battery indicator lights up:
When the battery has about 20 % power left the “Battery” indicator will turn yellow,
alerting you that you will need to change battery soon.
When your battery runs out (after about 2–3 hours), the notification signal will beep,
and the TTFields therapy will stop. When this happens the "Battery" indicator will turn
yellow and red Error light will light up. This notification signal sound is the same sound
the device makes for an error. However, in this case both the yellow "Battery" and red
"Error" indicators will light up instead of just the red light.
