these
keys
select

locations.
N.B,
Although
the
FREQUENCY RANGE
keys double
as
memory

does not imply
that
a
particu-
lar
memory
can only
accept frequencies
from
its
key's
range.
It is
emphasized
that
any
displayable
frequency
can be
stored
in
any
of
the five
locations.

five user-selected 'Spot' calibrated

At
these frequencies the
