Power Supply of the Construction Site Radio
The power supply of the construction site radio can take place
via the power-supply plug 24 or via a lithium ion battery 15.
Operation with Battery Pack
Use only original Bosch Professional 10.8 V lithium ion
batteries. Using other batteries can lead to injuries and
pose a fire hazard.
Note: Use of batteries not suitable for the construction site ra-
dio can lead to malfunctions of or cause damage to the con-
struction site radio.
Note: The battery pack is supplied partially charged. To en-
sure full capacity of the battery pack, completely charge the
battery pack in the battery charger before using for the first
time.
Use only the battery chargers listed on the accessories
page. Only these battery chargers are matched to the lith-
ium ion batteries used in your construction site radio.
The Lithium-Ion battery can be charged at any time without
reducing its service life. Interrupting the charging procedure
does not damage the battery.
The battery is equipped with a NTC temperature control
which allows charging only within a temperature range of be-
tween 0 °C and 45 °C. A long battery service life is achieved
in this manner.
Insert a battery into the battery port 17 in such a manner that
the connections of the battery face against the connections in
the charging compartment 17, and allow the battery to en-
gage in the battery port.
The battery charge-control indicator b appears on the display
as soon as a battery pack with sufficient voltage is inserted
and the construction site radio is not connected to the mains
supply via the power-supply plug 24.
The battery charge-control indicator b indicates the current
battery pack status. When the battery charge-control indica-
tor flashes, the battery pack must be charged.

Operation with Power-supply Plug
Observe the mains voltage! The voltage of the power
source for the power-supply plug must correspond with
the data on the type plate of the power-supply plug.
Open the protective cap of the 12 V connection socket 23. In-
sert the plug-in connector 25 of the 12 V power-supply plug
into the 12 V connection socket 23. Connect the power-sup-
ply plug to the mains supply.
Bosch Power Tools
Use only the original Bosch power-supply plug intended
for your construction site radio. This measure will ensure
proper operation of the construction site radio.
After removing the plug-in connector, reattach the protective
cap of the 12 V connection socket 23 to protect against
dirt/debris.
When not using the power-supply plug 24, it can be stored in
the storage compartment of the construction site radio. For
this, disengage the locking latch 21 and open the lid 20 of the
storage compartment.
Inserting/Replacing the Back-up Battery
In order to store the time in the construction site radio, back-
up batteries have to be inserted. Using alkali-manganese bat-
teries is recommended for this purpose.
To open the battery compartment, loosen screw 18 and re-
move battery lid 19. Insert the back-up batteries. When in-
serting, pay attention to the correct polarity according to the
representation on the outside of the battery lid.
Mount the battery lid 19 again and tighten it with screw 18.
Replace the back-up batteries when the time indication e be-
comes weaker and the construction site radio no longer
stores the time.
Always replace all batteries at the same time. Only use batter-
ies from one brand and with the identical capacity.
Remove the back-up batteries from the construction
site radio when not using it for longer periods. When
storing for longer periods, the back-up batteries can cor-
rode and discharge themselves.
Operation
Protect the construction site radio against moisture
and direct sunlight. The construction site radio is suitable
only for indoor use.
Audio Operation
Switching On and Off
To switch on the construction site radio, press the On/Off
button 3. The display 8 goes on and the last set audio source
after switching off the construction site radio is activated.
Note: When operating the first time via battery pack or when
not having used the construction site radio for a longer peri-
od, it may be necessary to press the On/Off button 3 several
times or longer, to switch the radio on.
Each time after pressing a button, the display 8 is illuminated
for several seconds.
To switch off the construction site radio, press the On/Off
button 3 again. The current audio source setting is stored.
To save energy, only switch the construction site radio on
when using it.
Adjusting the Volume
After switching on the construction site radio, a mean volume
level (value 10) is always set.
To increase the volume, press the "Vol +" button 6; to reduce
the volume, press the "Vol –" button 5. The volume setting
"VL" is indicated with a value between 0 and 20 for a few sec-
onds in indicator e on the display.
