3. Safety Instructions

Transportable world receivers are used in awide range of climate zones. Particularlywhen outdoors, make certain that ...

• the environmental limits are not excee-ded (see Section 2).

• Electronic devices can be damaged bymoisture.

• Extremely dry air can cause static char-ges that can lead to faulty functions.

• Excessive temperatures (e.g. direct sun-light) or very low temperatures (e.g. out-doors in winter) can permanently darkenthe liquid crystal display.

Transportable devices are particularly atrisk to accidental damage. You can reducethis risk by observing the following:

• Protect the device against heavy stres-ses, such as impacts and falls.

• Select a location in your travel luggagewhere it cannot be damaged or swit-ched on by other hard objects.

• When in areas with elevated securityrequirements (e.g. airplanes), it is bestto transport the device without the bat-teries inserted because it cannot becompletely switched off (clock, timerfunctions, ...).

b) External Power Supply

� Connect an external power supply ofDC 6...7.5V / 300 mA to the power sup-ply jack, as seen in the picture.

Note: The station memory described inSection 7 will be deleted if the device iswithout power for longer than about 30seconds.

You should therefore leave an externalpower supply connected while you changethe batteries – or finish changing them wit-hin 30 seconds!

4. Power Supply

Important: Make certain that the polarity iscorrect – both for the batteries as well asfor the external power supply. If the polarityis reversed, the device will be damaged.

a) About the Batteries

• Open the battery compartment on theback side of the device and insert fourbatteries of type "1.5V AA" according tothe labels in the battery compartment.

Note: Used batteries may not be dispo-sed of in household waste. Return theseto your retailer or to an appropriate col-lection site for disposal.

c) Switching Off with Time Delay

If you would like to listen to the radio for awhile longer, for instance before fallingasleep, but would like the device to switchoff automatically after a certain amount oftime (10...90 minutes), ...

press the button RADIO ON / SLEEPonly enough times until the desirednumber of minutes is shown in thedisplay ("10 ... 90").

The countdown begins immediately withthe first press of this button. If you do notalter the remaining time, the display willswitch back to the tuned frequency. Youcan check the remaining time or reduce itby pressing the ...

button RADIO ON / SLEEP again.

5. Switching On / Off

With this device, you can only switch thereception operation on and off. The clockfor time and date as well as the timer conti-nue to function as long as the device issupplied with power.

a) Switching On

To switch on the device, briefly pressthe button RADIO ON / SLEEP once."ON" appears initially in the display, follo-wed by the tuned frequency.

b) Switching Off Immediately

� To switch the the device off, press thebutton SNOOZE / Radio off , or ...

the button RADIO ON / SLEEP repea-tedly until "OFF" appears in the display.

6. Receive Mode

As soon as the device is switched on asdescribed under 5., it is already in receivemode.

a) Setting the Volume

� Press the buttons ▼ VOLUME ▲ toadjust the volume.

b) Selecting the Reception Range (Band)

� Select the desired reception range withthe sliding switch:

- USW = Ultra Short Wave

- MW = Medium Wave

- SW = Short Wave

- LW = Long Wave

c) Changing the Medium Wave Rage

The frequency range and tuning intervals ofMW vary by region:

Set the sliding switch to

- up in the region "USA"

- down in the region "Europe".

d) Searching for Stations

� Press briefly on one of the two TUNINGbuttons to search upward or downwardin steps.

� Hold one of the TUNING buttons pres-sed to start a scan. The device stops assoon as a sufficiently strong station isfound. Pressing the button again willcontinue the scan.

�

e) Short Wave (SW) Sensitivity

If the the scan process frequently lasts toolong, for instance because too many sig-nals are received in the evening, the sensiti-vity can be reduced to short wave (localreception).

� Set the sensitiviy switch to

- RX for local reception

- LX for long-range reception.

f) Sensitivity and Antennas

The telescoping antenna is responsible forUSW and short wave (SW). You can alterthe reception strength by adjusting thelength, inclination and direction of theantenna.

A ferrite antenna is built into the device formedium wave (MW) and long wave (LW)reception. Turn the entire device to alter thereception strength.

7. Memory

A total of 160 memory positions are availa-ble – specifically ...

- 5 blocks of 10 positions each for USW

- 5 blocks of 10 positions each for MW

- 5 blocks of 10 positions each for SW

- 1 block with 10 positions for LW.

The blocks are also designated as "pages".

This division into blocks is useful to allowthe stations to be saved according to ameaningful organisation principle. Forinstance ...

- by type: music, news, sports

- by location: local stations or frequentlyvisited travel destinations

- by person: if multiple family membersuse the device
