It is a designed mechanism for this device to switch to Standby mode automatically to prevent over-heating and possible damages due to the over-heating.

If the device switches to Standby mode automatically, please allow your device to cool down for around 15 minutes before switching it on again.

Make sure there is good ventilation for your device:

• Avoid placing your device just next to a wall. Keep your device at around one-footstep-distance from the wall.
• Avoid placing your device next to another electronic device. The electronic device may generate heat during operation, affecting ventilation of your device.

If the problem persists, contact Philips Consumer Care (Philips Support Page) for assistance.
