FAQ

In the instruction manual illustration for the JBL PROCRISTAL UV-C, the UV-C device is pictured connected behind the filter in an aquarium, yet it is pictured in front of the filter unit in the pond. Why is that?

A UV-C device is generally connected at the outlet of the pump in order to ensure a proper flow.

In the majority of pond filters (with the exception of pressure filters), the filter canister is higher than the pond water level and the water flows out of the filter then flows freely downwards back into the pond. The pond pump is in the pond. This is why the UVC water clarifier needs to be installed between the pump and the filter unit, to keep backwater out of the UV-C device.

PUSH messages from JBL

What are PUSH messages? As part of the W3C standard, web notifications define an API for end-user notifications that are sent to the user's desktop and/or mobile devices via the browser. Notifications appear on the end devices as they are familiar to the end user from apps installed on the device (e.g. emails). Notifications appear on the end user’s device, just like an app (e.g. for emails) installed on the device.

These notifications enable a website operator to contact its users whenever they have a browser open - it doesn’t matter whether the user is currently visiting the website or not.

To be able to send web push notifications, all you need is a website with a web push code installed. This allows brands without apps to take advantage of many of the benefits of push notifications (personalised real-time communications at just the right moment).

Web notifications are part of the W3C standard and define an API for end user notifications. A notification makes it possible to inform the user about an event, such as a new blog post, outside the context of a website.

JBL GmbH & Co. KG provides this service free of charge, and it is easy to activate or deactivate.
