This product is a replacement sensor for the DRI Sleeper Eclipse. Please follow the included instructions to pair the new Urosensor with the Eclipse alarm base. The Urosensor should be rinsed in cold water after each use and pat dry, or use a hair dryer to remove moisture between the sensing strips. Do not use chlorine-based cleaners or put the Urosensor in the washing machine or dryer, as this will damage the sensing strips. When not in use, the Urosensor should be placed in the cradle on the alarm base, which has been turned off and stored safely. The Urosensor is a consumable item because the battery cannot be replaced as the unit is permanently sealed to prevent moisture from entering the electronics.
