12 V Connection (see figure C)

With the 12 V connection socket, you can oper-

ate an external electrical device with a 12 V plug

and a max. current consumption of 1 A.

Remove the protective cap of the 12 V connec-

tion socket 29. Insert the plug of the external

electrical device into the 12 V socket outlet.

The 12 V connection socket is protected by a fuse

32. When no voltage is given after connecting an

external device, disengage locking latch 8 and

open the digital media bay flap 9. Unscrew the

fuse cap 31 and check if the inserted fuse 32 has

blown. If the fuse has blown, insert a new fine-

wire fuse (5 x 20 mm, 250 V max. voltage, 1 A rat-

ed current and quick-acting tripping characteris-

tic). Screw on and tighten fuse cap 31 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 construction site ra-

dio can become damaged.

The 12 V connection is also protected with an in-

ternal thermal fuse, which is blown/actuated

when overheated. The fuse is automatically reset

after the construction site radio has cooled down.

After removing the external plug, reattach the

protective cap of the 12 V socket outlet 29 to

protect against dirt/debris.

A/C Connection (“Power Outlets”)

(not for article number 3 601 D29 760)

Further external electrical devices/tools can be

operated via the A/C outlets. The socket outlets

can vary in consideration of country-specific

standards.

The total maximum permitted current consump-

tion of all connected electrical devices/tools

must not exceed the value in the following table

(also see the labeling on the housing under the

outlet cover 4):

Open one of the A/C outlet covers 4 and insert

the plug of an external electrical device into a

socket outlet 5 of the construction site radio.

time indication with separate power supply.

When back-up batteries with sufficient capacity
