About this unit
The 340T incorporates sophisticated Alarm and Sleep timer functions
that can turn on and off connected Cambridge Audio amplifiers fitted
with Control Bus inputs/outputs. A specific version of the azur remote is
provided, giving full remote control of the tuner functions in an
attractive and easy to use handset.
The 340T can only be as good as the system it is connected to. Please
do not compromise on your amplifier, speakers or cabling. Naturally we
recommend amplification and cabling from the Cambridge Audio range,
connected to suitably revealing loudspeakers. The use of an external
FM/AM aerial is strongly recommended to get the best from your 340T.

SAFETY PRECAUTIONS
Checking the Power Supply Rating
For your own safety please read the following instructions carefully before attempting
to connect this unit to the mains.
Check that the rear of your unit indicates the correct supply voltage. If your mains
supply voltage is different, consult your dealer.
This unit is designed to operate only on the supply voltage and type that is
indicated on the rear panel of the unit. Connecting to other power sources may
damage the unit.
This equipment must be switched off when not in use and must not be used
unless correctly earthed. To reduce the risk of electric shock, do not remove the
unit's cover (or back). There are no user serviceable parts inside. Refer servicing
to qualified service personnel. If the power cord is fitted with a moulded mains
plug the unit must not be used if the plastic fuse carrier is not in place. Should you
lose the fuse carrier the correct part must be reordered from your Cambridge
Audio dealer.
The lightning flash with the arrowhead symbol within an equilateral
triangle is intended to alert the user to the presence of uninsulated
‘dangerous voltage’ within the product’s enclosure that may be of
sufficient magnitude to constitute a risk of electric shock to
persons.
The exclamation point within an equilateral triangle is intended to
alert the user to the presence of important operating and
maintenance instructions in the service literature relevant to this
appliance.
This product complies with European Low Voltage (73/23/EEC)
and Electromagnetic Compatibility (89/336/EEC) Directives
when used and installed according to this instruction manual.
For continued compliance only Cambridge Audio accessories
should be used with this product and servicing must be referred
to qualified service personnel.

The crossed-out wheeled bin is the European Union symbol for
indicating separate collection for electrical and electronic
equipment. This product contains electrical and electronic
equipment which should be reused, recycled or recovered and
should not be disposed of with unsorted regular waste. Please
return the unit or contact the authorised dealer from whom you
purchased this product for more information.
Plug Fitting Instructions (UK Only)
The cord supplied with this appliance is factory fitted with a 13 amp mains plug
fitted with a 3 amp fuse inside. If it is necessary to change the fuse, it is important
that a 3 amp one is used. If the plug needs to be changed because it is not suitable
for your socket, or becomes damaged, it should be cut off and an appropriate plug
fitted following the wiring instructions below. The plug must then be disposed of
safely, as insertion into a 13 amp socket is likely to cause an electrical hazard.
Should it be necessary to fit a 3-pin BS mains plug to the power cord the wires
should be fitted as shown in this diagram. The colours of the wires in the mains
lead of this appliance may not correspond with the coloured markings identifying
the terminals in your plug. Connect them as follows:
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 letter ‘L’ or coloured RED.
The wire which is coloured GREEN/YELLOW
must be connected to the terminal which is
marked with the letter ‘E’ or coloured GREEN.
If your model does not have an earth wire,
then disregard this instruction.
If a 13 amp (BS 1363) plug is used, a 3 amp fuse must be fitted, or if any other
type of plug is used a 3 amp or 5 amp fuse must be fitted, either in the plug or
adaptor, or on the distribution board.

IMPORTANT SAFETY INSTRUCTIONS
Please take a moment to read these notes before installing your Azur tuner, they
will enable you to get the best performance and prolong the life of the product. We
advise you follow all instructions, heed all warnings and keep the instructions for
future reference.
This unit must be installed on a sturdy, level surface. Since the power transformers
generate a magnetic hum-field of moderate strength, a turntable should not be
located nearby.
Do not defeat the safety purpose of the polarized or grounding-type plug.
A polarized plug has two blades with one wider than the other. A grounding type
plug has two blades and a third grounding prong. The wide blade or the third
prong are provided for your safety. If the provided plug does not fit into your outlet,
consult an electrician for replacement of the obsolete outlet.
The unit must be installed in a manner that makes disconnection of a mains plug
from the mains socket outlet (or appliance connector from the rear of the unit) possible.
Do not plug your 340T directly into a power amplifier unless it has a variable
output level.
Do not route the power cable so that it can be walked upon or damaged by other
items near it.
The unit requires ventilation. Do not situate it on a rug or other soft surface and
do not obstruct any air inlets or outlet grilles.
Do not place in a sealed area such as a bookcase or in a cabinet. Any space open
at the back (such as a dedicated equipment rack) is fine however.
When using for the first time it is advisable that it is left on, playing music, for at
least 36 hours prior to critical listening. For subsequent use, a warm up period of
10-15 minutes is recommended for maximum enjoyment.
If you do not intend to use this unit for a long period, switch it to standby and
unplug it from the mains socket. Also unplug the unit during lightning storms.
WARNING – To reduce the risk of fire or electric shock, do not expose this unit to
rain or moisture. This unit must not be exposed to dripping or splashing water or
other liquids. No objects filled with liquid, such as vases, shall be placed on the
unit. In the event of spillage, switch off immediately, disconnect from the mains
supply and contact your dealer for advice.
To clean the unit, wipe its case with a moist, lint-free cloth. Do not use any
cleaning fluids containing alcohol, ammonia or abrasives. Do not spray an aerosol
at or near your 340T.
Ensure that small objects do not fall through any ventilation grille. If this happens,
switch off immediately, disconnect from the mains supply and contact your dealer
for advice.
Refer all servicing to qualified service personnel. Servicing is required when the
unit has been damaged in any way, such as a damaged power-supply cord or plug,
liquid has been spilled or objects have fallen into the unit, the unit has been
exposed to rain or moisture, does not operate normally, or has been dropped.
If you have checked the troubleshooting guide in the manual with no improvement,
do not attempt to repair, disassemble or reconstruct the unit. A serious electric
shock could result if this precautionary measure is ignored.
Do not install near any heat sources such as radiators, heat registers, stoves, or
other apparatus (including amplifiers) that produce heat.

AC Power Socket
FM Aerial
Once all connections have been made, plug the AC power cable into an
appropriate mains socket. Your 340T is now ready for use.
Connect an aerial to the FM 75 ohm socket (a simple wire aerial is
supplied for temporary use). Extend the lead and move the aerial around
until you get the best reception.
Audio Output
Connect to your amplifier using RCA /phono cables.
For continued use, we strongly recommened using a 75 ohm outdoor

Control Bus
AM Loop Aerial
The Control Bus carries control information, in the form of demodulated
remote control signals, between the tuner and other Cambridge Audio
devices connected to it. The 340T will respond to appropriate commands,
as well as generating specific amplifier On/Off commands according to
the tuner’s Alarm and Sleep functions.
Please note the supplied antenna wire is supplied for temporary indoor
use only. Connect each end of the single length antenna to the antenna
terminals. Place the antenna as far from the main system as possible to
prevent unwanted noise and to obtain optimum reception.
