Note: The following information applies to all devices.

Cleaning devices and the associated hygiene should be observed in everyday life. Dirt in the area of the speaker and microphone can also impair the sound quality.

Removing metal dust

Since the speakers are magnets, metal dust from the production environment accumulates here. This can usually be removed again using simple means.

	The metal dust can be removed from the speakers using a magnet (e.g., from a whiteboard)
	With the help of a bag in which the magnet is wrapped, the metal dust can then be easily removed from the magnet again

Removing dirt

	Cleaning clay is suitable for cleaning devices in narrow spaces
	This is pressed into the spaces and the dirt particles stick to it
	The material should not be pressed into the openings with sharp tools, as this can also damage the membrane

Why should devices not be cleaned with compressed air?

The devices are often IP68-rated and therefore dustproof and waterproof. However, this protection has its limits when pressure is applied. The usual pressure for compressed air nozzles in industry is above 4 bar. At this pressure, the device is not cleaned, but instead the dirt is pushed deeper into the device and even compacted. The pressure can also cause seals and membranes, which are necessary for IP protection, to be destroyed, thus compromising the tightness.

ATTENTION: IP protection is part of the Ex approval. If the membrane is damaged, water can penetrate the device, for example.

Disinfect

For cleaning and disinfecting i.safe MOBILE products, we recommend a spray consisting of 70 % pure alcohol (99.x % e.g., 2-propanol, isopropanol) and 30 % clean distilled water.

	Leave the explosion hazardous area.
	Switch off the device.
	Remove the charging cable and any other plugs from the device.
	Spray the device with the spray and wait a moment.
	Clean the device with a dry microfiber cloth.
	Make sure the device is completely dry (min. 5 minutes) before switching on.

Notes:

Although the disinfecting effect is better with a higher concentration, we recommend a maximum mixture of 70/30 to avoid damaging the materials used.

Attention: Damage caused by the use of aggressive disinfectants is not covered by the guarantee! As soon as you notice a change in color on your device, you must under no circumstances use your device within a potentially explosive area!

For detailed information on the effect of the disinfectant mixture and the exposure time, refer to the local government information.
