Assembly
Power Supply of the Radio Charger
The power supply of the radio charger can take place via the
mains supply or via a lithium ion battery inserted in the charg-
ing compartment
22. When the battery is used for power sup-
ply, only the functions audio operation and power supply of
external devices via the integrated USB connection, are avail-
able.

Observe the mains voltage! For power supply via mains,
the voltage of the power source must correspond with the
data on the type plate of the radio charger. Radio chargers
marked with 230 V can also be operated with 220 V.
Battery Insertion/Removal (see figure A)

Use only original Bosch Professional 14.4 V and 18 V
lithium ion batteries. Using other batteries can lead to in-
juries and pose a fire hazard.
Note: Use of batteries not suitable for the radio charger can
lead to malfunctions of or cause damage to the radio charger.
Open locking latch 23 of the battery lid (“Charger/Battery
Bay”) and fold out battery lid 24.
Insert a battery into the charging compartment
22 in such a
manner that the connections of the battery face against the
connections in the charging compartment
22, and allow the
battery to engage in the charging compartment.
As soon as a battery with sufficient volt-
age is inserted, the battery inserted in-
dicator
l appears on the display.
The battery inserted indicator l flashes
when the battery is low.
To remove the battery 25, press the release button on the
battery and pull it out of the charging compartment 22.
After inserting or removing the battery, close the battery lid
24. Lock the battery lid by engaging the locking latch 23 in the
housing and then pressing down.

If required, wear protective gloves when removing the
battery. The battery can heat up considerably when
charging.
Inserting/Replacing the Back-up Battery
(see figure A)
In order to store the time in the radio charger, back-up batter-
ies have to be inserted. Using alkali-manganese batteries is
recommended for this purpose.
Open locking latch 23 of the battery lid (“Charger/Battery
Bay”) and fold out battery lid 24.
Remove the battery
25, if required.
To open the back-up battery lid 18, press on the latch 17 and
remove the back-up battery lid. Insert the back-up batteries.
When inserting, pay attention to the correct polarity accord-
ing to the representation on the inside of the back-up battery
compartment.
Mount the back-up battery lid 18 again.
“REPLACE AA BATTERY WHEN UNIT NO LONGER KEEPS
CORRECT TIME”: Replace the back-up batteries when the ra-
dio charger no longer stores the time.
