Disengage locking latch 19 and open the digital media bay
flap 20. Connect the USB plug of the external device to the
USB port 45 of the radio charger. To start the charging proce-
dure, the external device must possibly also be selected as
the audio source on the radio charger.
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 41.
Insert the plug of the external electrical device into the 12 V
socket outlet.
The 12 V connection socket is protected by a fuse 44. When
no voltage is given after connecting an external device, disen-
gage locking latch 19 and open the digital media bay flap 20.
Unscrew the fuse cap 43 and check if the inserted fuse 44 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
43 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
radio charger can become damaged.
The 12 V connection is also protected with an internal thermal
fuse, which is blown/actuated when overheated. The fuse is
automatically reset after the radio charger has cooled down.
After removing the external plug, reattach the protective cap
of the 12 V socket outlet 41 to protect against dirt/debris.
AC Connection ("Power Outlets")
(not for article number 3 601 D29 660)
Further external electrical devices/tools can be operated via
the AC 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 5):
Article number Total max. current consumption
(in A)
3 601 D29 600 15
3 601 D29 630 9
3 601 D29 670 12
3 601 D29 6W0 15
3 601 D29 6X0 9
Open one of the AC outlet covers 5 and insert the plug of an
external electrical device into a socket outlet 6 of the radio
charger.
Time Indication
The radio charger is equipped with a time indication with sep-
arate power supply. When back-up batteries with sufficient
capacity are inserted in the back-up battery compartment
(see "Inserting/Replacing the Back-up Battery", page 18), the
time can be stored even when the radio charger is disconnect-
ed from the AC power supply or the battery.
Bosch Power Tools
Setting the Time
– To set the time, press and hold the "Clock" button 29
until the hours indication flashes in the time indication
display o.
– Press the "Seek +" button 33 or the "– Seek" button 35
until the correct hour setting is indicated.
– Press the "Clock" button again, so that the minutes indica-
tion flashes in the time indication display o.
– Press the " Seek +" button 33 or the "– Seek" button 35
until the correct minute setting is indicated.
– Press the "Clock" button a third time to store the time set-
ting.
Energy Saving Mode
To save energy, you can switch the time indication in display
39 off.
For this, press and hold the On/Off button 38 when switching
off audio operation (see "Switching Audio Operation On/Off",
page 18), until there is no indication on the display.
To switch the time indication on again, press the On/Off but-
ton 38 once.

Working Advice

Temperature Monitoring for Battery Operation
When the radio charger is operated only via battery (no mains
supply), the battery temperature is monitored.
– When the battery temperature is below –10 °C or above
50 °C, the temperature warning k flashes on the display.
– When the battery temperature is above 70 °C, the radio
charger automatically switches off to protect the battery.
When the battery has cooled down, the radio charger can
be put into operation again.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Store the battery only within a temperature range between
–20 °C and 50 °C. As an example, do not leave the battery in
the car in summer.
A battery that is new or has not been used for a longer period
does not develop its full capacity until after approx. 5 charg-
ing/discharging cycles.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
Observe the notes for disposal.
Troubleshooting – Causes and Corrective
Measures
Cause Corrective Measure
