this key is used. Normally, you will use the “100 %”
value; once 100 % is selected, you typically will not
need to use this key.

(
MAP
)]
Key
This key switches the Display between the Great
Circle Map and the regular Rotator Control compass
display.
Advice
: If the Great Circle display is utilized, you
probably already know the approximate location of
the other station on the map; so even if the country
name and the city name are not entered into the radio,
the Great Circle Map provides a convenient tool for
rotating the antenna to the optimum heading.
If your own location is not indicated at the center of
the Great Circle Map, please set the local time (which
registers the location where the radio is operated). If
this is not done, the various functions of the World
clock and Great Circle Map will not function cor-
rectly. Regarding the setting of the Local time, please
see the “PLEASE READ THIS FIRST” section.
