Safety information 1

WARNING

Dangerous x-ray radiation and/or dangerous electrical voltage during checks and adjustment work steps!

If not observed, death or serious physical injury can occur.

The following items must be complied with when performing service work and tests:

- The product-specific safety information in the documents,

- The general safety information contained in ARTD Part 2.

• Connect the MOBILETT only to a mains power supply outlet
