The cables / cords used on the unit must not exceed the lengths specified below.
Operating environment
For the intended use, the unit may only be operated in premises used for medical pur-
poses.
The unit may be operated in the vicinity of an electrosurgical unit. The safety instruc-
tions for the unit and the electrosurgical unit must be observed. Please read the safety
instructions on the following subjects in particular:
• distance between the unit and the electrosurgical unit. In this User Manual, refer
to the safety instruction Stacked units.
• Distances between the unit and the electrosurgical unit’s cords.
• Distances between the unit's cords and the electrosurgical unit’s cords.
Position the units and cords so that they are as far apart as possible.

Note: A minimum safety distance of 30 cm should be maintained between the unit and portable HF telecommunications
units that transmits in the stated frequency band. This includes mobile phones, WLAN and RFID, and Bluetooth units. Failure
to comply may lead to a reduction in the unit’s performance features.
Interference may occur in the vicinity of units marked with the following symbol.
a) The pulse modulation is defined as a square-wave signal with a 50% duty factor.
