Setting the Rod Antenna
The construction site radio is provided with a mounted rod an-
tenna 10. For radio operation, point the rod antenna toward
the direction that enables the best reception.
When the reception is insufficient, position the construction
site radio at a different location that enables better reception.
Note: When operating the construction site radio in the direct
vicinity of radio-communication equipment or radio trans-
ceivers, or other electronic equipment, the radio reception
can be subject to interference.
If the rod antenna 10 should become loose, tighten it directly
at the housing by turning in clockwise direction.
Setting/Storing Radio Stations
Press the "Source" button 22 until "FM" is indicated for the
ultra-short wave reception range or "AM" for the medium
wave reception range in display element m.
To set a certain radio frequency, turn the "Tune" adjust-
ment knob 19 clockwise to increase the frequency, and anti-
clockwise to decrease it. During setting, the frequency is indi-
cated in display section n, then in j.
To scan for radio stations with a high signal strength,
press and briefly hold the "– Seek" button 23 to scan down
and the "Seek +" button 21 to scan up the frequency scale.
The frequency of the found radio station is briefly indicated in
display n and then in j.
When the reception of a suitable signal is sufficiently strong,
the construction site radio automatically switches to stereo
reception. The indicator for stereo reception i appears on the
display.
To store a set station, press the "Memory" button 16. The

lected preset. The indicators e and d no longer flash.
