Masser products are purpose built electronic devices for professional use. Any update, maintenance or repair work should therefore be done by a professional. Our main service is in Rovaniemi, Finland.
Devices sent to service should be packed carefully. Remember to include a cover letter, where the need for service and return address are mentioned. Our service will contact you if necessary.
If you are outside EU, please contact us before sending the device. We will send to you instructions.
