The

Functional

Principle

of

the

radio

‐

controlled

clock

The

RC

clock

receives

time

frame

signals

from

the

transmitter

DCF77

by

the

built

‐

in

antenna

system.

Once

it

has

been

set

correctly

by

the

time,

the

RC

clock

continues

running

on

its

own,

internal,

comparing

the

indicated

time

with

the

time

information

of

the

transmitter

DCF77

once

every

hour.

The

best

position

The

clocks

reception

system

is

virtually

omni

‐

directional,

which

makes

it

possible

to

position

the

clock

for

the

best

visual

effect.

Use

screws

with

wall

plugs

for

mounting.

Respecting

good

receiving

conditions

always,

the

radio

‐

controlled

clock

must

not

be

secured

to

metallised

surfaces.

Connection

of

an

external

antenna

If

a

particular

place

of

installation

does

not

guarantee

good

reception

conditions,

an

external

antenna

can

be

connected

easily

to

the

movement

by

means

of

a

jack

plug

to

improve

reception

immediately,

without

of

any

manipulation.

It

is

to

order

separately,

also

later

onwards.

Starting

the

radio

‐

controlled

clock

Insert

two

1.5

V

batteries

the

correct

way

round

(LR

14

alkaline).

The

second

hand

and

hour

hand,

and

afterwards

the

minute

hand,

move

automatically

in

rapid

motion

to

“12.00”

‐

position

 ‐ 

the

reception

phase

begins.

When

the

RC

clock

movement

receives

the

time

frames

the

second

hand

begins

to

move

in

1

‐

second

steps.

The

minute

hand

also

begins

to

move.

After

2

minutes

of

receiving

time

the

second

hand,

minute

hand

and

hour

hand

simultaneously

set

themselves

automatically

to

the

correct

time

in

rapid

motion.

If

the

LED

flashes

and

the

second

hand

moves

erratically,

this

means

that

perfect

reception

is

not

possible

at

the

present

moment

and

the

reception

phase

is

extended

for

a

certain

period

of

time.

Reception

monitoring

display

The

clock

receives

a

time

frame

in

the

59

th

minute

of

each

hour

and

the

internal

time

memory

is

synchronized

accurately

to

the

second.

As

sign

for

this,

the

minute

hand

continues

to

jump

from

full

minute

to

full

minute.

If

perfect

reception

is

not

possible,

the

minute

hand

changes

to

a

virtually

continuous

motion,

i.e.

the

minute

hand

moves

to

a

total

of

30

intermediate

positions

each

minute.

This

near

continuous

motion

does

not

change

back

to

a

motion

in

one

‐

minute

steps

until

perfect

radio

contact

occurs

at

a

later

full

hour.

Battery

change

display

“low

‐

batt”

With

this

clock

the

battery

voltage

is

checked

several

times

each

day.

If

it

drops

below

the

limit

voltage

it

will

be

indicated

visually

by

the

LED

flashing

at

10

‐

second

intervals,

although

there

is

still

sufficient

power

reserve

for

reliable

operation.
