Operation with Battery Pack
Note:
Use of batteries not suitable for the construc-
tion site radio can lead to malfunctions of or cause
damage to the construction site radio.
Note:
The battery pack is supplied partially
charged. To ensure full capacity of the battery
pack, completely charge the battery pack in the
battery charger before using for the first time.
Use only the chargers listed in the technical
data.
Only these chargers are matched to the
lithium-ion batteries permitted for use 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.
Insert a battery into the battery port
17
in such a
manner that the connections of the battery face
against the connections in the battery port
17
, and
allow the battery to engage 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 indicator flashes, the battery pack
must be charged.
To remove the battery pack
15
, press the unlocking
buttons
16
and pull the battery pack out of the bat-
tery port
17
.
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
. Insert the plug-in connector
25
of the
12 V power-supply plug into the 12 V connection
socket
23
. Connect the power-supply plug to the
mains supply.
Use only the original BTI power-supply plug
intended for your construction site radio.
This
measure will ensure proper operation of the con-
struction 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 construc-
tion 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 ra-
dio, back-up batteries have to be inserted. Using al-
kali-manganese batteries is recommended for this
purpose.
To open the battery compartment, loosen screw
18
and remove battery lid
19
. Insert the back-up bat-
teries. When inserting, pay attention to the correct
polarity according to the representation on the out-
side of the battery lid.
Mount the battery lid
19
again and tighten it with
screw
18
.
Replace the back-up batteries when the time indi-
cation
e
becomes weaker and the construction site
radio no longer stores the time.
Always replace all batteries at the same time. Only
use batteries from one brand and with the identical
capacity.
Remove the back-up batteries from the con-
struction site radio when not using it for longer
periods.
When storing for longer periods, the
back-up batteries can corrode 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 construc-
tion 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 period, 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
