3. Safety Instructions

Transportable world receivers are used in a wide range of climate zones. Particularly when outdoors, make certain that ...

• the environmental limits are not exceeded (see Section 2).
• Electronic devices can be damaged by moisture.
• Extremely dry air can cause static charges that can lead to faulty functions.
• Excessive temperatures (e.g. direct sunlight) or very low temperatures (e.g. outdoors in winter) can permanently darken the liquid crystal display.

Transportable devices are particularly at risk to accidental damage. You can reduce this risk by observing the following:

• Protect the device against heavy stresses, such as impacts and falls.
• Select a location in your travel luggage where it cannot be damaged or switched on by other hard objects.
• When in areas with elevated security requirements (e.g. airplanes), it is best to transport the device without the batteries inserted because it cannot be completely switched off (clock, timer functions, ...).

KH2025-2026 IB UK 01.04.2004 11:29 Uhr Seite 7

4. Power Supply

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

a) About the Batteries

- Open the battery compartment on the back side of the device and insert four batteries of type "1.5V AA" according to the labels in the battery compartment.

Note: Used batteries may not be disposed of in household waste. Return these to your retailer or to an appropriate collection site for disposal.

b) External Power Supply

11 Connect an external power supply of DC 6...7.5V / 300 mA to the power supply jack, as seen in the picture.

Note: The station memory described in Section 7 will be deleted if the device is without power for longer than about 30 seconds.

You should therefore leave an external power supply connected while you change the batteries – or finish changing them within 30 seconds!

KH2025-2026_IB_UK 01.04.2004 11:29 Uhr Seite 8

5. Switching On / Off

With this device, you can only switch the reception operation on and off. The clock for time and date as well as the timer continue to function as long as the device is supplied with power.

a) Switching On
⑨ To switch on the device, briefly press the button RADIO ON / SLEEP once. "OT" appears initially in the display, followed by the tuned frequency.
b) Switching Off Immediately
15 To switch the device off, press the button SNOOZE / Radio off, or ...
⑨ the button RADIO ON / SLEEP repeatedly until "OFF" appears in the display.

c) Switching Off with Time Delay

If you would like to listen to the radio for a while longer, for instance before falling asleep, but would like the device to switch off automatically after a certain amount of time (10...90 minutes), ...

⑨ press the button RADIO ON / SLEEP only enough times until the desired number of minutes is shown in the display ("10 ... 90").

The countdown begins immediately with the first press of this button. If you do not alter the remaining time, the display will switch back to the tuned frequency. You can check the remaining time or reduce it by pressing the ...

⑨ button RADIO ON / SLEEP again.

KH2025-2026 IB UK 01.04.2004 11:29 Uhr Seite 9

6. Receive Mode

As soon as the device is switched on as described under 5., it is already in receive mode.

a) Setting the Volume
⑧ Press the buttons ▼ VOLUME ▲ to adjust the volume.
b) Selecting the Reception Range (Band)
6 Select the desired reception range with the 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 of MW vary by region:

13 Set the sliding switch to
- up in the region "USA"
- down in the region "Europe".

d) Searching for Stations

5 Press briefly on one of the two TUNING buttons to search upward or downward in steps.
5 Hold one of the TUNING buttons pressed to start a scan. The device stops as soon as a sufficiently strong station is found. Pressing the button again will continue the scan.

KH2025-2026 IB UK 01.04.2004 11:29 Uhr Seite 10

e) Short Wave (SW) Sensitivity

If the scan process frequently lasts too long, for instance because too many signals are received in the evening, the sensitivity can be reduced to short wave (local reception).

4 Set the sensitiviy switch to

- RX for local reception

- LX for long-range reception.

f) Sensitivity and Antennas

The telescoping antenna is responsible for USW and short wave (SW). You can alter the reception strength by adjusting the length, inclination and direction of the antenna.

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

7. Memory

A total of 160 memory positions are available – 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 allow the stations to be saved according to a meaningful organisation principle. For instance ...

• by type: music, news, sports
• by location: local stations or frequently visited travel destinations
• by person: if multiple family members use the device
