voltage is correct. Insert the plug on the end of the supplied power
cord into the AC power socket on the back of the radio.
DC operation
For outdoor use, you can power the radio by using 2v DC input
socket from a DC power supply (example, from the power supply of
vehicles or boats). An AC power adaptor with 1 Ampere and center
positive in polarity can also power the radio in house.
Antenna setup for FM reception
The radio comes with built-in AM/FM antenna and external antenna.
To use FM internal antenna, make sure to switch FM external/
internal antenna switch in the back of your radio to internal antenna
position (i.e. INT. FM ANTENNA). As for external antenna, there
are two types of antenna can be used to improve FM reception.
You can connect the supplied FM antenna to the F-type antenna
terminal and adjust the wire for best reception. You can also
connect a 75 ohm coaxial cable of outdoor antenna to the terminal.
Make sure to switch external/internal antenna switch to external
position while connecting the outdoor / rooftop antenna.
Note:
In some of the European countries, you may have to use adaptor
plug to connect with the outdoor/rooftop antenna in case your
antenna has an incorrect type of plug.
