The Tourguide System 2020-D offers optimum digital speech transmission

for conferences and guided tours e�g� in factories or museums� The use of RF

transmission allows freedom of movement for all members of the group� Six

preset intermodulation-free receiving frequencies offer high ﬂexibility and

adaptability�

The Tourguide System 2020-D operates in the 863 MHz – 865 MHz frequency

band, which is license-free in Europe�

SK 2020-D bodypack transmitter

You can connect one of the following Sennheiser microphones (to be ordered

separately) to the bodypack transmitter:

• Clip-on microphones:

ME 2-II, ME 4, MKE 1-ew, MKE 2-EW Gold

• Headmics:

ME 3-II, HS 2-ew BK, HS 2-ew BE, SL Headmic 1 SB, SL Headmic 1 BK,

SL Headmic 1 BE

• Hand-held microphones with special connecting cable:

bodypack transmitter/radio microphone� You can also charge the bodypack

transmitter with the BA 2015 accupack inserted plus an additional spare accu-

pack� 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 accupacks�

• Safe storage and transportation of the system components�

The L 2021-40 charger

The L 2021-40 charger can charge a total of 40 HDE 2020-D-II and/or
