The push-buttons for the frequency range selection are located on the top of the unit; they tend to get a little dusty and usually need a cleaning after the set has not been used for a longer time period.

The reception characteristics are not outstanding, the tuning is coarse and in the shortwave ranges, exact tuning to a station on a known frequency is hardly possible. The strongest international stations can be found, but the frequency marks are too wide to tune a frequency with accuracy.
