On your marks - filter - start! Priming problems? Let us help!

Even though the operating instructions on how to use the start button of any JBL external filter ( External filters ) are really clear and comprehensible, JBL receives enquiries on this subject time and again. Admittedly: The FIRST actuation of the "start button" on the pump head of all JBL CristalProfi e External filters requires some force. But after pressing it down for the first time it goes very easily. Many users stop the "pumping process” too early! They probably think that pressing the start button ONCE starts, continues and completes the priming process. This is not the case. The necessary volume to start the pump cannot be achieved by pressing the start button only once. Think of this start button as an air pump, which, of course, cannot pump up the whole tyre with just one motion. If you pump the start button several times, you’ll see the water start to collect in the hose. Only stop when the water flows. This means the pumping was successful. After that the water will continue to flow on its own and fill the filter completely. 

Remember: Pump the button, don’t just press it - it’s that easy!

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.
