Controlling External Audio Sources
For audio sources connected via the SD/MMC slot 34 or the
USB port 33, playback can be controlled via the construction
site radio. The number of the selected track is displayed at the
left of indicator d and the number of available tracks on the
right.
Play/Pause:
– To start playback, press the play/pause button 24. The
playing time of the current track is displayed in indicator j.
– To interrupt or continue the playback, press the
play/pause button 24 again. The current playing time
flashes in indicator j.
Selecting Tracks:
– To select a track, press the "– Seek" button 23 to scan
down or the "Seek +" button 21 to scan up, until the num-
ber of the desired track is displayed on indicator d.
– To start playback, press the play/pause button 24.
Random Playback/Repeat:
– For random playback of all tracks on the card or the USB
stick, press the random playback/repeat button 20 once.
The indicator f appears on the display.
– To repeat all tracks in the current folder/directory, press
the random playback/repeat button 20 a second time. The
indicator g appears on the display.
Note: Only in this function, the number of the current fold-
er/directory on the card or USB stick will appear on the
right-hand side of indicator d. To change the folder/direc-
tory, you have to return to the normal playback first and se-
lect a track from the desired folder/directory.
– To repeat only the current track, press the random play-
back/repeat button 20 a third time. The indicator h ap-
pears on the display.
– To return to normal playback mode, press the random
playback/repeat button 20 a fourth time, so that none of
the indicators f, g or h appear on the display.
– To start playback, press the play/pause button 24.
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 sock-
et. Connect an appropriate playback device to the AUX cable.
After removing the AUX cable, reattach the protective cap of
the "LINE OUT" socket 30 to protect 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 operate and charge
most devices whose power supply is possible via USB (e.g.,
various mobile phones).
1 609 92A 1U1 | (16.11.15)
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 construction site radio. To start the charging
procedure, the external device must possibly also be selected
as the audio source on the construction site radio.
12 V Connection (see figure C)
With the 12 V connection socket, you can operate an external
electrical device with a 12 V plug and a max. current con-
sumption of 1 A.
Remove the protective cap of the 12 V connection socket 29.
Insert the plug of the external electrical device into the 12 V
socket outlet.
The 12 V connection socket is protected by a fuse 32. When no
voltage is given after connecting an external device, disengage
locking latch 8 and open the digital media bay flap 9. Unscrew
the fuse cap 31 and check if the inserted fuse 32 has blown. If
the fuse has blown, insert a new fine-wire fuse (5 x 20 mm,
250 V max. voltage, 1 A rated current and quick-acting tripping
characteristic). Screw on and tighten fuse cap 31 again.
Note: Use only 1 A fuses for a max. voltage of 250 V ("250V
1A FUSE FOR 12V OUTLET"). When using other fuses, the
construction site radio can become damaged.
The 12 V connection is also protected with an internal ther-
mal fuse, which is blown/actuated when overheated. The
fuse is automatically reset after the construction site radio
has cooled down.
After removing the external plug, reattach the protective cap
of the 12 V socket outlet 29 to protect against dirt/debris.
A/C Connection ("Power Outlets")
(not for article number 3 601 D29 760)
Further external electrical devices/tools can be operated via
the A/C outlets. The socket outlets can vary in consideration
of country-specific standards.
The total maximum permitted current consumption of all con-
nected electrical devices/tools must not exceed the value in
the following table (also see the labeling on the housing under
the outlet cover 4):
Article number Total max. current consumption
(in A)
3 601 D29 700 15
3 601 D29 730 9
3 601 D29 770 12
3 601 D29 7W0 15
3 601 D29 7X0 9
Open one of the A/C outlet covers 4 and insert the plug of an
external electrical device into a socket outlet 5 of the con-
struction site radio.
Time Indication
The construction site radio is equipped with a time indication
with separate power supply. When back-up batteries with suffi-
cient capacity are inserted in the back-up battery compartment
(see "Inserting/Replacing the Back-up Battery", page 8), the
time can be stored even when the construction site radio is dis-
connected from the A/C power supply or the battery.
