Overview of the system
HDE 2020 D and EK 2020 D receivers
The receivers are easy to use and comfortable to wear.
The built-in LC display shows all the important in-
formation at a glance (receiving channel, reception
quality, charge status of the built-in Lithium-polymer
rechargeable battery as well as the currently set
volume). The rocker button allows fast and easy
setting of the desired channel.
The EK 2020 D allows you to connect any headphones
or an induction loop for wearers of hearing aids.
The system can be expanded at any time by adding
additional receivers.
EZL 2020-20 L charging case
The charging case simultaneously recharges up to
20 stethoset receivers with their built-in rechargeable
batteries, as well as the BA 2015 accupack of the
bodypack transmitter/radio microphone. You can also
charge the bodypack transmitter with the BA 2015
accupack inserted plus an additional spare accupack.
The channel copy function lets you set all receivers to
the same channel at the press of a button.
Additional features of the charging case:
Quick charge of accupacks.
Automatic detection of full charge and subsequent
switching to trickle charging so the accupacks can
remain in the charger even when they have been
fully charged.
Highest possible operational reliability, since
temperature and voltage of the accupacks are
monitored during charging.
Long accupack service life due to overcharge
protection and recovery of deep-discharged accu-
packs.
Safe storage and transportation of the system
components.
