Hi Gusstone,

Combilift has procedures on its Knowledgebase that you can follow if you have access.

If you do not have access, you can submit a "Technical Support" request via the form at the bottom of the Combilift main web site, www.combilift.com , the team will get back to you. There is no login required and no charge for this and the team are happy to help. The form works easily on a mobile phone also.

Thanks Richard
