with

the

controls.

There

are

six

knobs

and

ten

pushbuttons

controlling

the

functions

of

the

receiver.

Each

control

performs

a

different

function.

But

instead

of

discussing

each

control

separately,

we

will

illustrate

how

they

work

together

to

control

the

the

730.

turn it

down

(counterclockwise).

Push

the
