Connecting External Audio Playback
(see figure C)
The current audio signal of the construction site
radio can also be transferred to other playback
devices (e.g. amplifier and speakers).
Remove the protective cap of the "LINE OUT"
socket 30 and insert the 3.5 mm plug of a
matching AUX cable into the socket. Connect an
appropriate playback device to the AUX cable.
After removing the AUX cable, reattach the pro-
tective cap of the "LINE OUT" socket 30 to pro-
tect against dirt/debris.
Power Supply of External Devices
The power supply of external devices via the
12 V and the AC connection is possible only
when the construction site radio is connected to
mains, and not via the inserted battery.
When the construction site radio is connected
to the mains supply, this is confirmed by the lit
green control lamp 3.
USB Connection
With the USB connection, it is possible to oper-
ate and charge most devices whose power sup-
ply is possible via USB (e.g., various mobile
phones).
Disengage locking latch 8 and open the digital
media bay flap 9. Connect the USB plug of the
external device to the USB port 33 of the con-
struction site radio. To start the charging proce-
dure, the external device must possibly also be
selected as the audio source on the construc-
tion site radio.
