SPECIFICATIONS
Digital Tourguide stethoset receiver
The HDE 2020-D
stethoset TourGuide receiver is
comfortable to wear and integrates both the receiver
and headphones. The powerful battery ensures up to
8 hours operating time. The stethoset receiver
automatically deactivates itself the moment that it
is taken off, thus battery life will be preserved. Tour
participants will be able to individually adjust the
volume through a rotary control on the receiver,
without the need to even take the device off. The
LC display provides information of volume, battery
status, quality of reception and the channel being
listened to. Channels can easily be set and adjusted by
using the middle buttons.
