Setting the Rod Antenna
The construction site radio is provided with a mounted rod an-
tenna 10. For radio operation, point the rod antenna toward
the direction that enables the best reception.
When the reception is insufficient, position the construction
site radio at a different location that enables better reception.
Note: When operating the construction site radio in the direct
vicinity of radio-communication equipment or radio trans-
ceivers, or other electronic equipment, the radio reception
can be subject to interference.
If the rod antenna 10 should become loose, tighten it directly
at the housing by turning in clockwise direction.

Connecting External Audio Sources (see figure C)
Apart from the integrated radio, various external audio sourc-
es can be played.
AUX-In connection 1: The AUX-In connection 1 is particularly
suitable for audio sources to be placed outside of the digital
media bay (e.g. a CD player). Remove the protective cap of
the "AUX 1 IN" socket 28 and insert the 3.5 mm plug of the
provided or of another matching AUX cable into the socket.
Connect the AUX cable to an appropriate audio source.
After removing the AUX cable, reattach the protective cap of
the "AUX 1 IN" socket 28 to protect against dirt/debris.
For external audio sources via the following connections,
open locking latch 8 and open lid 9 of the "Digital Media
Bay".
– SD/MMC connection: Insert a SD or MMC card into the
SD/MMC slot 34. The labelling of the card must face to-
ward the fuse cap 31. Playback of the card can be started
as soon as the track number as well as the number of avail-
able tracks on the card are displayed in indicator d. To re-
move the card, briefly press on the card, which is then
ejected.
– USB connection: Insert a USB stick (or the USB plug of an
appropriate audio source) into USB port 33. Playback of
the USB stick can be started as soon as the track number
as well as the number of available tracks on the stick are
displayed in indicator d. To remove the USB stick, pull it
out of the USB port.
– AUX-In connection 2: AUX-In connection 2 is particularly
suitable for audio sources that can be placed inside of the
digital media bay (e.g. a MP3 player). Insert the 3.5 mm
plug of the provided AUX cable into the "AUX 2 IN" socket
35. Connect the AUX cable to an appropriate audio source.
When small enough, the connected external audio source can
be fastened into the digital media bay using the Velcro strap of
the holder 36.
