caused by lightning or power line surges.

003
If the radio is left unattended and used for a long period of time, remove the batteries. The
batteries may leak and damage furniture or your radio.
Do not attempt to service the receiver yourself. Removing the cover may expose you to dangerous
voltage, and will void the warranty. Refer all servicing to authorized service personnel.
Never push objects of any kind into this radio through opening as they may touch dangerous
voltage points or short-out parts that could result in a re or electric shock. Never spill liquid of
any kind into the product.
The appliance should be serviced by qualied service personnel when:
The power supply cord or the plug has been damaged.
Objects have fallen or liquid had been spilled into the radio.
The radio has been exposed to rain or water.

Read and understand all safety and operating instructions before the radio is operated.
Recharge the batteries in any case at least every 2 months.
Make sure the Battery Select switch inside the battery compartment is set to the “NiMH” position.
Put the batteries in the compartment while paying attention to the correct polarity of the batteries (+ and -).
First use: Charge new batteries in one continuous, uninterrupted, charge until they are full. This
rst charge may take longer than normal. For longer battery life it is advised to always recharge
in one continuous, uninterrupted charge until batteries are full and to not recharge again while the
batteries are still full.
New batteries will only reach their full capacity after some time of use (several charge and
discharge cycles).
Leave the complete group of batteries in place inside the radio and do not use these batteries
or a few of them for other purposes. This will result in a mix of (fully) charged and (partly) empty
batteries. This can seriously damage the batteries and radio when recharged.
It is advised to only charge batteries at room temperatures between 5 degrees C – 35 degrees C.
In lower or higher temperatures full charge cannot be achieved.
Depending on the capacity of the batteries, charging from “empty” to “full” can take several hours,
even up to 6 hours or more.
Do not charge batteries when the radio is hot or exposed to heat or heat sources.
It is advised to clean the metal contacts of the batteries and of the charger inside the radio e.g. with
a contact-spray from time to time.
Do not use a mix of old and new rechargeable batteries.
Do not use a mix of rechargeable and non-rechargeable batteries.
Do not use a mix of full and empty rechargeable batteries.
Do not use batteries that have a different mAh capacity.
Do not use damaged, deformed or leaking batteries.
Important information on charging and
using rechargeable batteries

005
Battery level indication is an approximate indication only and can vary with battery type that is used.
Batteries can become hot during charging.
In cold conditions the capacity of batteries will be much lower than when used at normal room
temperature.
Batteries (even when supplied with the radio), as being consumables, do not fall under the
warranty conditions of the radio.
Batteries should not be disposed of by incineration and with household waste.
Disposable batteries should be taken to a suitable recycling center if possible.
Risk of explosion if the battery is replaced by an incorrect type.

Before you insert the batteries, check the NiMH / Alkaline switch position. If you use non-rechargeable
batteries, make sure the NiMH / Alkaline switch which located inside the battery compartment is
switched to Alkaline position. If you use rechargeable batteries, make sure to switch NiMH / Alkaline
switch to NiMH position.
Battery operation
Open the battery cover on the rear of the unit by pushing the latch downward.
1.
NOTE
When using alkaline batteries the battery switch must be
placed in the alkaline position. Failure to do so could result
in serious damage to the batteries or radio.
Insert 4xLR6 (AA size) batteries into the space in the compartment. Ensure the batteries are
inserted in accordance with the diagram shown. Close the battery compartment door.

Charging the batteries
Battery operation
The charge indicator will ash green indicating that batteries are charging. Batteries will be fully
charged in around 4-6 hours depending on their capacity. The charge indicator shows a steady
green light when battery charging is complete.
During the charging process, if a battery is detected as
faulty / damaged, the charge LED indicator will show red
light. The battery indicator will be shown with a cross under
the corresponding battery number and the display will
switch to standby mode after 10 seconds. Pressing the Info
button can view the battery status display again.
The low battery indicator showing red, reduced power, distortion and a ‘stuttering’ sound are all
signs that the batteries may need replacing.
If the radio is not to be used for any extended period of time it is recommended that the batteries
are removed from the radio.
●If extended listening using batteries is anticipated, then the use of rechargeable batteries is
recommended.

When using rechargeable batteries the battery switch
must be placed in the NiMH position. Batteries will only be
charged when the radio is switched off and connected to the
AC adaptor.

Charging the batteries
Battery operation
● Duration for charging your batteries fully can vary according to the mAh capacity of the
batteries. Higher mAh batteries require a longer charging time.
● When the batteries are exhausted, the battery light will show red for a short while.The radio will
then switch itself off. It may not be possible to switch the radio back on until the batteries are
recharged, or until the radio is connected to the mains adaptor.
● Under some conditions the charging LED indicator may switch off after flashing briefly. This
may happen if the batteries are already freshly charged, or if the radio detects that you may be
attempting to recharge alkaline batteries or mixed different types or capacity of rechargeable
battery. In these cases the charging will be stopped.
NOTE
The mains adaptor is used as the means of connecting the radio to the mains supply. The mains
socket used for the radio must remain accessible during normal use. In order to disconnect the
radio from the mains completely, the mains adaptor should be removed from the mains socket
outlet completely.
IMPORTANT
Using the AC power adaptor
The AC power adaptor required for this unit should be 7.5 volts DC at 0.8A center pin positive. Insert
the adaptor plug into the DC socket on the left side of the radio. Plug the adaptor into a standard mains
socket outlet.
Whenever the adaptor is used, the batteries are automatically disconnected. The AC adaptor should
be disconnected from the main supply when not in use.

012
Carefully extend the telescopic aerial.
Press and hold the Power button to switch on your radio.
If this is the rst time the radio is used, a quick scan of the Band III DAB channels will be carried
out. If the radio has been used before the last used station will be selected.
During the scanning process, as new stations are detected the station counter will increase and
the stations will be added to the list which is stored in the radio. The bar graph indicates the
progress of the scan.
When the scanning is completed the rst station (in numeric-alpha order 0...9...A....Z) will be selected.
If the station list is still empty after the scan, your radio will show “No stations found” for a moment.
If no signals are found it may be necessary to relocate your radio to a position giving better reception.
Press and hold the Power button to switch on your radio.
Press the Source button until the 'DAB radio' mode is selected.
Rotate Tuning control knob to step through the list of available stations.
Press Select button to select and tune to the desired station.
Use the Volume Up / Down button to set the sound level as needed. Alternatively to access the
station list using the DAB menu, press and hold the Menu button and then choose 'Station List'.
