[. . . ] High volume! ³· Even short exposure to high volume levels will damage your hearing!Set the volume for the connected headphones to the minimum before putting the headphones on. First, set the volume control to the lowest volume by turning it to the left as far as possible. When people use headphones, they tend to choose a higher volume than with loudspeakers. Listening at high volume levels for long periods can lead to permanent hearing defects. Please protect your hearing, Sennheiser headphones have an excellent sound quality even at low volumes. Activating/deactivating the lock mode Each receiver of the EM 550 G2 has a lock mode that can be activated or deactivated via the operating menu (see "Activating/deactivating the lock mode" on page 25). The lock mode prevents that the receiver is accidentally programmed or switched off during operation. 14 The operating menu The operating menu is the same for both receivers of the EM 550 G2 and can be used almost intuitively. To ensure that adjustments to the settings can be made quickly and "without looking", the necessary operating steps for the twin receiver and the ew 500 G2 transmitters are similar.

The operating steps for adjusting the settings via the menu are similar for both receivers of the EM 550 G2.
