When deciding where to place the device, please note that furniture surfaces are covered by various types of varnish and plastic, most of which contain chemical additives. These additives can corrode the device supports, leaving residues on the furniture surfaces which can be difficult or impossible to remove.

POWER SUPPLY

Mains operation

Note:
Check that the mains voltage on the type plate (on the bottom of the device) corresponds to your local mains supply. If this is not the case, contact your specialist dealer.

Plug the mains cable supplied into the »AC ~« socket on the device.
Plug the mains cable into the socket (230V~, 50/60 Hz).

Note:
If there are batteries in the device, these are switched off automatically during mains operation.
The only way to disconnect the device from the mains supply is to pull out the plug.

Battery operation

You can also operate the device using standard batteries (not supplied). In this case, you must disconnect the mains power cable.

Open the battery compartment by pressing the area marked with arrows on the drawing and pushing down the cover.
Insert four batteries (4x1.5V, Type IEC, AM 2, LR 14, C size) according to the polarity marked on the battery compartment.

Note:
Remove the batteries when they are flat or when you know that the device will not be used for a long period of time. When the batteries are low, a battery symbol appears and flashes in the display. This function does not work when the power cable is plugged into the device. No liability is accepted for damage resulting from leaking batteries.

Environmental note:
Batteries, including those which contain no heavy metal, must not be disposed of with household waste. Please dispose of used batteries in an environmentally sound manner. Observe the legal regulations which apply in your area.

Inserting back-up batteries

During mains operation, the back-up batteries ensure that stored settings are not lost in the case of a power failure or when the device is briefly disconnected from the mains.

Open the battery compartment by pressing the area marked with arrows on the drawing and pushing down the cover.
When inserting the batteries (micro type, e.g. AM 3, LR 6, AA size) in the small compartment, observe the polarity marked on the compartment base.

Note:
If no main batteries are inserted and there is no mains power supply, you have approximately 10 seconds to change the back-up batteries.

Additional information for units sold in the UK

Units sold in the UK are suitable for operation from a 240V ac, 50Hz mains supply.

The range of multi-system receivers is built to work in most European countries. However, the mains plug and socket system for the UK differs from many European countries.

This appliance has been supplied with a fitted, non-removable, approved converter plug for use in the UK. This converter plug is fitted with a 5A rated fuse.

In case this appliance is supplied with a moulded 2-pin Euro plug only, which is unsuitable for UK operation, this must be cut off and immediately disposed of. An approved 13A, 3-pin UK plug should then be fitted by a qualified electrician.

Note:
The severed Euro plug must be destroyed to avoid a possible shock hazard should it be inserted into a socket elsewhere.

If a non-rewireable 3-pin plug or a rewireable 13A (BS1363) 3-pin plug is used, it must be fitted with a 5A ASTA or BSI approved BS1362 fuse. If any other type of plug is used it must be protected by a 5A fuse either in the plug, or at the distribution board. If this type of plug becomes defective, ensure that the fuse is removed before disposal, to eliminate potential shock hazard.

If it is necessary to change the fuse in the non-rewireable plug, the correct type and rating (5A ASTA or BSI approved BS1362) must be used and the fuse cover must be refitted. If the fuse cover is lost or damaged, the lead and plug must not be used until a replacement is obtained. Replacement fuse covers should be obtained from your dealer.

The wires in the mains lead are colour coded in accordance with the following code:

BLUE – NEUTRAL
BROWN – LIVE

As the colours of the wires in the mains lead of your appliance may not correspond with the coloured marking identifying terminals in your plug, proceed as follows:

Connect the BLUE coloured wire to plug terminal marked with the letter "N" or coloured black.

Connect the BROWN coloured wire to the plug terminal marked with the letter "L" or coloured red.

In no circumstance must any of the wires be connected to the terminal marked with the letter "E", earth symbol "", coloured green, or green & yellow.

Replacement mains lead sets can be obtained from your local dealer, or by contacting Grundig Consumer Relations (01788 570088) Moulded 3-pin lead set, suitable for UK use:
