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:
y Quick charge of accupacks.
y 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.
y Highest possible operational reliability, since
temperature and voltage of the accupacks are
monitored during charging.
y Long accupack service life due to overcharge
protection and recovery of deep-discharged
accupacks.
y Safe carrying and storage of system components.
