Batteries

• Open the battery compartment and insert 3 alkaline

batteries of the type R6, UM 3 or AA.

• Remove the batteries when they are exhausted or if they are

not going to be used for a long period of time.

Note: 

If the 

DC 4.5 V 

->+

socket is in use, the battery

supply will switch off automatically.

Note on Environmental Protection

Do not throw exhausted batteries in the household
refuse. 
Hand over the old batteries to your dealer or
public collecting points when buying new ones.

Warning for weak batteries :

When the batteries run low, the sound volume declines
gradually. The indication 

appears on the display.

Continued operation with low batteries causes the radio to turn
off automatically, other malfunctioning and losing programmed
time settings and preset radio stations. In this case, remove the
batteries and press a paper clip through the 

RESET 

hole.

Readjust the time settings and the preset radio stations. To
prevent that the radio is switched on accidentally, use the

LOCK

-switch when packing the radio or putting it away.

POWER SUPPLY

AC Mains adapter (not included)

You can connect the set to the mains using a 
mains adapter.
Only use a mains adapter which supplies
4.5 V DC with the negative pole at the centre
pin of the plug (

->+

).

Before connecting the mains adapter

• Check that the mains voltage indicated on the type plate of

the adapter matches your local mains voltage.

• If the mains adapter is equipped with a voltage selector, set

this to the local voltage.

• Connect the mains adapter to the 

DC 4.5 V 

->+

socket

of the set and to the wall socket.

Power failure

– If the power supply is interrupted, the programmed time

settings and preset radio stations will be kept in the memory
for 10 min. or more.

– If the AC power is disconnected from the 4.5 DC socket,

the batteries (if present) will take over the supply.

Time zones

The earth rotates around its axis in 24 hours and around the
sun in one year.
These movements are responsible for the time differences and
the seasons on earth. Due to the direction of rotation of the
earth it is always earlier in the day to the west of where you
are and later in the day to the east of where you are.
The earth is divided into 24 time zones with a difference of
one hour between adjacent zones. The system is based on one
standard time zone, namely 

UTC 

(Coordinated Universal Time),

previously 

GMT 

(Greenwich Mean Time). Generally speaking,

short-wave stations announce their broadcasts in 

UTC

.

To check which time zone you are now at, use the world map
on the back of the set.

Short Wave (SW)

Your world receiver can receive a number of wavebands. Most
of these are known and tuning to the required station will soon
become a matter of routine, as the stations are always to be
found at the same place on the dial and are thus tied to a
fixed wavelength and frequency. With short wave this is
unfortunately not always the case. Short wave transmitters have
to change their wavelengths fairly often. In the short-wave
range between 10 and 100-metre wavelength (frequencies of
30-3 MHz resp.) nine bands between 10 and 50 metres are
allocated to short-wave broadcasting, with another four bands
between 60 and 120 metres for broadcasting in the earth’s
tropical areas. The latter are roughly located between the
latitudes of 30° north and 30° south, i.e. around the equator.
Most short-wave broadcasting bands, indicated in the short-
wave table, are allocated for the whole world and can be
used for international broadcasting. They are so far the only
wavelengths which allow direct radio reception over long
distances. So in addition to the broadcasting services, there is
a large number of other users of short wave, for example radio
amateurs, shipping and aviation, radio navigation etc.

SW Tuning mode (meterband/continuous)

Your Yachtboy P-2000 has a built-in SW frequency (

SW

FREQ.

) tuning mode selection switch inside the battery

compartment.
• Select 

A

, if you only want to get reception for the stations

with the frequency within the meter-bands.

• Select 

B

, in case you wish to obtain the frequencies in

between the gaps of the meterbands.
