The E4 is designed for home use. The rubberized outer case is designed to protect the electronics against splashes and minor drops. With proper care your E4 should last for years.
Cleaning and Disinfection
Before switching between users, carefully clean all parts of the device that come in contact with the skin. The disinfection processes should include one or more of the following methods:
-
Exposure to UV lamp.
-
Cleansing with cotton soaked with a small quantity of ethyl or isopropyl alcohol.
-
Cleansing with a solution containing Alkyl C12-16 Dimethylbenzyl Ammonium Chloride.
Power off the device before cleansing. Make sure any residual cleaning solution has dried prior to powering on the the E4 after cleansing.
E4 Battery
The E4's battery is a rechargeable LiPo battery. Like the batteries in most mobile phones, the E4 battery will lose some capacity over time and may require servicing / replacement after several-hundred charge cycles. To prolong the life of the E4's battery make sure to store the device in a cool and dry environment with the battery charged to approximately 50% capacity. Leaving the E4 connected to a power outlet after the charging indicator LED has turned off may reduce the life of the battery.
