The L 2021-40 charger is part of the Tourguide 2020 D system. The  
Tourguide 2020 D system offers optimum digital speech transmission for  
guided tours e.g. in factories or museums and during conferences. The  
use of RF transmission allows freedom of movement for all members of  
the group. Six fixed transmission frequencies in “Tourguide mode” and  
eight transmission frequencies in “Conference mode“ offer high flexibility  
and adaptability. The L 2021-40 charger simultaneously recharges up to  
40 HDE 2020 D stethoset receivers with their built-in rechargeable  
batteries. The channel copy function lets you set all receivers to the same  
channel at the press of a button.  
In addition, the charger allows you to directly configure the stethoset  
receivers via a PC. You can connect up to 125 chargers to a single PC,  
allowing you to simultaneously configure up to 5000 receivers.  
Additional features of the charger:  
• Quick charge of receiver rechargeable batteries  
• Highest possible operational reliability, since temperature and voltage  
of the rechargeable batteries are monitored during charging
