Position the radio charger in such a manner that the signals
from outlet opening
8 of the remote control can directly reach
reception lens 31 on the radio charger. When the remote con-
trol cannot be pointed directly against a reception lens, the
working range is reduced. By reflecting the signal (e. g.
against walls), the working range can be improved even for in-
direct signals.
The remote control 2 can be stored in carrying handle 3.
When using the remote control, you can fasten it e.g., to a belt
loop by opening loop-clip button
16 and attaching the remote
control.

Battery Replacement
To replace the battery, unscrew the screw of the battery com-
partment on the backside of the remote control and remove
the battery lid.
When inserting the new battery, pay attention to the correct
polarity. Screw on the battery lid again.

Replace the battery only with a new battery of the same
type. Danger of explosion when inserting other battery
types.
 Remove the battery from the remote control when not
using it for longer periods. When storing for longer peri-
ods, the battery can corrode and discharge itself.
 Keep the battery away from children. Children could
swallow the battery and cause a hazardous situation for
their health.
Battery Charging (see figure A)
The charge procedure begins as soon as the mains plug of the
radio charger is plugged into a socket outlet and a battery
25
is inserted into the charging compartment 22 (see “Battery
Insertion/Removal”, page 17).
During the charging procedure, the
“CHARGING” indicator m flashes on
the display. The “CHARGING” indicator goes out when the
battery is fully charged.
Due to the intelligent charging method, the charging condi-
tion of the battery is automatically detected and the battery is
charged with the optimum charging current, depending on
battery temperature and voltage.
This saves the battery and ensures that it is always fully
charged when in the radio charger.
The charged battery 25 can be removed from the charging
compartment 22 or (when inserted in the charging compart-
ment) be used for power supply during audio operation.

If required, wear protective gloves when removing the
battery. The battery can heat up considerably when
charging.
Power Supply of External Devices
The power supply of external devices via the 12 V and the AC
connection is possible only when the radio charger is con-
nected to mains, and not via the inserted battery.
When the radio charger is connected to the mains supply, this
is confirmed by the lit green control lamp
4.
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).
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 ther-
mal 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.
A/C Connection (“Power Outlets”)
(not for article number 3 601 D29 660)
Further external electrical devices/tools can be operated via
the A/C outlets. The socket outlets can vary in consideration
of country-specific standards.
