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

20stethoset 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.
