Setting the Rod Antenna
The radio charger is provided with a mounted rod antenna 21.
For radio operation, point the rod antenna toward the direc-
tion that enables the best reception.
When the reception is insufficient, position the radio charger
at a different location that enables better reception.
Note: When operating the radio charger in the direct vicinity
of radio-communication equipment or radio transceivers, the
radio reception can be subject to interference.
If the rod antenna 21 should become loose, tighten it directly
at the housing by turning in clockwise direction.

ment knob 30 clockwise to increase the frequency, and anti-
clockwise to decrease it. During setting, the frequency is indi-
cated in display section o, then in j.

press and briefly hold the "– Seek" button 35 to scan down
and the "Seek +" button 33 to scan up the frequency scale.
