SAFETY PRECAUTIONS

A triangle with a lightning symbol draws the user's

attention to "dangerous voltage" without insulation in the

cabinet which may be high enough to entail a risk of

electric shock.

A triangle with an exclamation mark draws the user's

attention to important instructions for use and

maintenance in the accompanying manual, which should

be studied.

A symbol for CLASS II (double insulation)

WARNING:

CAUTION:

TO MINIMISE THE RISK OF FIRE OR ELECTRICAL SHOCK, DO NOT EXPOSE

THE UNIT TO RAIN OR MOISTURE. DO NOT OPEN THE CABINET AS IT

CONTAINS DANGEROUS VOLTAGE. ONLY QUALIFIED TECHNICIANS ARE

ALLOWED TO CARRY OUT REPAIR AND SERVICE.

if the plug of the power cord needs to be replaced, it is important that the

replacement is identical to the plug to be replaced, or that the new plug has been

recommended by the manufacturer

TO AVOID ELECTRICAL SHOCK, IT IS IMPORTANT TO INSERT THE PLUG

CORRECTLY INTO THE SOCKET.

IMPORTANT INFORMATION

Handling instructions

- The top and back panel of the unit may become warm after prolonged use. This is not due to a defect.

- Turn off the power when the unit is not used.

Protect the power cord

- Follow the instructions below to prevent abnormal operation, electrical shock, fire or personal injury:

- Hold the plug firmly when inserting it into the socket.

- Avoid heat-producing devices.

- Do not place objects on the power cord.

- Do not carry out service work on or change the power cord.

Positioning

Do not place the unit in any of the fol. places:

- In sunlight, close to heat-producing devices or in an enclosed rack.

- In places with high temperatures (40C or more) or high relative humidity (90% or more).

- In dirty places as some internal parts may be damaged.

Condensation

Condensation may occur in the following cases:

- When the unit is moved directly from a cold to a warm place.

- When the unit is used in a room where the radiator has just been switched on or a place where the cold air from the air-conditioning system is directed at the unit.

- If the unit is used in the summer in a warm and humid room just after it has been moved from an air-conditioned room.

- If there is steam or a high level of humidity in the room.

In case of condensation, the unit will not work

properly. Turn off the unit. Unplug the unit and leave it for 2-3 hours. The unit will then have adapted to the environment and any condensation will have disappeared.

Do not put your fingers or any other objects into the unit

- Touching the internal parts is dangerous and may cause injury or damage. Do not open the cabinet.

- Do not place any foreign matter in the unit.

Interference

Placing the unit near a television set, radio or video player may cause poor picture and sound quality. In that case, move the unit further away from the television set, radio or video player.

CONNECTION TO THE MAINS

Connection to the mains

HAM75 B

150W

220-240V AC~50Hz

USE ONLY WI TH 250V F USE

FUSE :T2A L 25 0V

Do not turn on the power before all connections have been made correctly. Check that all connections have been made correctly before turning on the power. Check that the mains voltage is 220-240V AC50Hz before turning on the power.

Connection to the mains

Check that all other connections have been made correctly before inserting the mains plug into the wall socket. Then insert the plug into a suitable socket. If the unit is to be used abroad, you may need an adapter.

REMOTE CONTROL INSTALLATION

Installation of batteries

1 Remove the cover as illustrated.

2 Position two batteries of the type AAA/R03/UM4

in the battery compartment. Make sure that the orientation of the batteries is correct (see drawing at bottom).

- Do not mix new and old batteries and do not use different types of batteries.

- If the remote control is not used for prolonged periods, remove the batteries from the remote control to avoid corrosion.

3 Replace the cover.

Using the remote control

Direct the remote control at the sensor on the front panel of the unit. When the remote control signal is received, the unit reacts accordingly. The remote control works within a range of 6 metres.

- Sometimes the remote control does not work well in strong light. You may have to move the unit if it is a problem.

- Malfunction may occur if other remote controls are used near the unit.

- Do not place any objects on the remote control, as the batteries may become flat if a key is depressed constantly.

- Make sure that there are no obstacles between remote control and unit.

- Do not position the unit behind tinted glass as it may reduce the maximum range of the remote control.

Speaker Outputs Left and Right

To avoid damage to the amplifier, make sure it is NOT plugged into an AC outlet while connecting up or disconnecting speaker wire to the speaker outputs. The amplifier has two pair of speaker outputs on the back labeled Speaker Left and Speaker Right. Using a suitable speaker wire, connect the right speaker (of Speaker A or B) to the Speaker Right connectors and the left speaker to the Speaker Left (of Speaker A or B) . Pay careful attention to match the positive (red) and negative (black) terminals on your speakers to the positive (red) and negative (black) terminals on back of the amplifier.
