The HDE 2020 D stethoset receivers

Overview of the system

The HDE 2020 D stethoset receivers

The stethoset receivers are easy to use and comfortable to wear. The built-in display shows all the important information 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 system can be expanded at any time by adding additional stethoset receivers.

The EZL 2020-20 L charging case

The charging case simultaneously recharges the rechargeable batteries of up to 20 stethoset receivers and the accupack of the bodypack transmitter/ wireless microphone. You do not have do remove the accupack from the bodypack transmitter to recharge it. You can recharge one other accupack in addition to the bodypack transmitter. 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:

yQuick charge of accupacks.

yAutomatic 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.

yHighest possible operational reliability, since temperature and voltage of the accupacks are monitored during charging.

yLong accupack service life due to overcharge protection and recovery of deep-discharged accupacks.

ySafe carrying and storage of system components.
