Our phone booths SOLO have changed slightly over the years. That’s why the solutions for this issue vary depending on the generation.
Please enter the serial number of your phone booth below. We’ll then show you how to solve the issue.
You can find the serial number on the door side inside the light slot of the ceiling element. It’s easiest to take a photo with your smartphone, as the number is slightly hidden.
The light in your phone booth SOLO should switch on automatically as soon as you enter the booth.
If this no longer happens, please check two things:
Please follow these steps:
Were you able to solve the problem? Great.
Does the light still remain off?
Together, we’ll definitely find a solution. Please send us a message here including the serial number(?) of your phone booth and a description of the problem.
We’ll get back to you shortly.
