Pressing

the

left

tuning

button

will

change

the

station

frequency down

the

band. Pressing

the

right button

will

change

the

station

frequency

up

the

band.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The Auto Selector controls whether the tuning buttons

 

will

change

the station

frequency

by

one

channel

spacing

(Manual

Mode),

 

or

automatically

move

to

the

next

usable

station

(Auto

Mode).

The

status

of

this

mode is

indicated

in

the

display

window

by

the

logo

“AUTO”.

 

 

 

 

 

 

 

 

 

 

 

In

most

situations, the

Auto

Mode

is

most

useful, as it allows the tuner

to

increment automatically

to

the

next usable station, avoiding multiple button

strokes to find a station.

However,

the

operation

of

the

Auto

Mode is keyed to signal strength, so weak stations may be “missed”

in

the

 

Auto

Mode.

Therefore,

when

searching for a weak station, use Manual Mode.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The

945

has

a

total

of

18

memory preset

locations that

may

be used

for

storing and recalling

either

AM

of FM

stations.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The Memory Preset buttons 1 through 9

 

access

memory

locations

1

through 9. Pressing the +10 Shift

button

simultaneously

with

a

1

through

9

button

accesses

memory

locations

11

through 19. Note

that

there

is

no

memory

10.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The selected memory location is indicated in the display window underneath the “CH” logo.

The

memory presets available

from

the

front

panel are

also available from

the

Remote Control,

but

use

a

different

set

of buttons.

 

 

 

 

 

 

 

 

 

 

 

The

Next button may be used

to

increment

the

tuner to the next higher

preset

number. The

‘1’

or

‘11’

buttons may be used to “jump”

from one group of preset numbers to another. This avoids having

to

press

the

 

Next

button

repeatedly to

access

a distant

preset

number.

 

 

 

 

 

Example: The tuner is set to preset 4. To get to preset 13, press ‘1 1 ', then press Next twice.

To

store

a station

into

a memory location, first set the

tuner to

the

desired broadcast

station.

 

Then press

the

Memory

button.

A

 

“MEMORY” logo will appear in

the

display

for

about

four

seconds.

 

During

this

period, press the desired preset button 1 through 9, or

+10

with 1

through 9.

The

station will

now be

committed

to

that

memory

location.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Note that

any

station,

AM or FM, may be stored in

any

location.

The

tuner

will

automatically

switch

between

AM

and FM

according

to

the

station stored.

It may

be

most

convenient

to

store

the

stations

in

numerical

order,

or

to

store them

in

descending order

of

most frequently used, or

to

use

1

through

9

for

FM, and

11

through

19

for

AM.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Storing stations into memory is not available from the Remote Control.

The 945 has the ability

to detect

FM stations

broadcasting

in stereo,

and automatically switch on its

multiplex decoder. Stereo

decoding

is indicated

by the logo

“STEREO”

visible in the display.

The background noise level of a stereo broadcast increases as signal strength decreases. The tuner has the ability to detect low signal strength and automatically switch to mono to reduce this background noise.

There are

situations,

particularly when a

weak signal strength fluctuates, that it is best to force the tuner

into mono

with the Mono Control. Mono

Mode is active when the button is lighted green, as well as the

“STEREO”

logo in

the display being

extinguished.

The Mono Control is not available from the Remote Control.
