WARNING: WHEN USING ELECTRIC PRODUCTS, BASIC PRECAUTIONS SHOULD ALWAYS
BE FOLLOWED, INCLUDING THE FOLLOWING:
The MFC42 is designed to be used in a standard household environment.
Power requirements for electrical equipment differ from area to area. The operating voltage of this
MFC42 is preset at the factory according to its intended destination. However, before connecting,
check to see that the VOLTAGE SELECTOR on the rear panel is set to the correct voltage for your
area. If not, please set it correctly before plugging in the power cord. If in doubt, consult a qualified
electrician or AKAI professional dealer.
@ 60 Hz for USA and Canada
@ 50 Hz for Europe
If the VOLTAGE SELECTOR is not set correctly for your area:
Confirm that the power cord is disconnected.
Remove the VOLTAGE SELECTOR with a screw driver and
replace it so that the correct voltage for your area is lined with
the marker. Also, change the fuse according to the chart
indicated on the rear panel as necessary.
PROTECTING YOURSELF AND THE MFC42
Never touch the AC plug with wet hands.
Always disconnect the MFC42 from the power supply
by pulling on the plug, not the cord.
Allow only an AKAI professional dealer or qualified professional engineer to repair or reassemble
the MFC42. Apart from voiding the warranty, unauthorized engineers might touch live internal
parts and receive a serious electrical shock. There are no serviceable parts inside.
Do not put, or allow anyone to put any object, especially metal objects, into the MFC42.
Use only a household AC power supply. Never use a DC power supply.
If water or any other liquid is spilled into or onto the MFC42, disconnect the power, and call your
Make sure that the unit is well-ventilated, and away from direct sunlight.
To avoid damage to internal circuitry, as well as the external finish, keep the MFC42 away from
sources of direct heat (stoves, radiators, etc.).
Avoid using aerosol insecticides, etc. near the MFC42. They may damage the surface, and
Do not use denatured alcohol, thinner or similar chemicals to clean the MFC42. They will damage
Modification of this equipment is dangerous, and can result in the functions of the MFC42 being
impaired. Never attempt to modify the equipment in any way.
Make sure that the MFC42 is always well-supported when in use (either in a specially-designed
equipment rack, or on a firm level surface).
When installing the MFC42 in a 19" rack system, always allow 1U of ventilated free space
above it to allow for cooling. Make sure that the back of the rack is unobstructed to allow a clear
In order to assure optimum performance of your MFC42, select the setup location carefully,
and make sure the equipment is used properly. Avoid setting up the MFC42 in the following
1. In a humid or dusty environment
2. In a room with poor ventilation
3. On a surface which is not horizontal
4. Inside a vehicle such as a car, where it will be subject to vibration
5. In an extremely hot or cold environment

THIS APPARATUS MUST BE EARTHED
This equipment is fitted with an approved non-rewireable UK mains plug.
To change the fuse in this type of plug proceed as follows:
1) Remove the fuse cover and old fuse.
2) Fit a new fuse which should be a BS1362 5 Amp A.S.T.A or BSI approved type.
3) Refit the fuse cover.
If the AC mains plug fitted to the lead supplied with this equipment is not suitable for your type of
AC outlet sockets, it should be changed to an AC mains lead, complete with moulded plug, to the
appropriate type. If this is not possible, the plug should be cut off and a correct one fitted to suit the
AC outlet. This should be fused at 5 Amps.
If a plug without a fuse is used, the fuse at the distribution board should NOT BE GREATER than
THE SEVERED PLUG MUST BE DESTROYED TO AVOID A POSSIBLE
SHOCK HAZARD SHOULD IT BE INSERTED INTO A 13 AMP SOCKET
The wires in this mains lead are coloured in accordance with the following code:
GREEN and YELLOW
As the colours of the wires in the mains lead of this apparatus may not correspond with the coloured
markings identifying the terminals in your plug, please proceed as follows:
The wire which is coloured GREEN and YELLOW must be connected to the terminal which is
marked with the letter E or with the safety earth symbol
or coloured GREEN or coloured
GREEN and YELLOW.
The wire which is coloured BLUE must be connected to the terminal which is marked with the
letter N or coloured BLACK.
The wire which is coloured BROWN must be connected to the terminal which is marked
with the etter L or coloured RED.
THIS APPARATUS MUST BE EARTHED
Ensure that all the terminals are securely tightened and no loose strands of wire exist.
Before replacing the plug cover, make certain the cord grip is clamped over the outer sheath of the
lead and not simply over the wires.
This equipment has been tested and found to comply with the limits for a Class B digital device
pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and
can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
