Cyrus FM7 INSTALLATION
POSITIONING THE UNIT
The Cyrus FM7 may be positioned as a free standing unit
or alongside another piece of audio equipment. Never
stand the unit on top of a power amplifier, which may
generate heat. The Cyrus FM7 Tuner must always sit
horizontally on a flat firm surface.
CONNECTING THE UNIT
The Mains Supply
The moulded IEC connector of the mains lead supplied
should be plugged in to the power inlet
6
on the rear of
the unit.
The mains fuse
5
is located on the rear panel next to the
power switch. It must only be replaced with the following
types:
U.K. / Europe - 230V T100mA/20mm
N. America / Far East - 115V T200mA/20mm
In the U.K., the FM7 comes with the mains plug fitted. In
the unlikely event that the plug fuse should need replacing
ensure that it is only replaced with a 3 Amp Fuse.
Connecting to an Amplifier
Using the interconnect lead provided connect one set of
the phono plugs to their corresponding audio outputs on
the rear of the tuner
1
. The other end of the lead should
then be connected to the tuner input of your amplifier. If
there is no tuner input available any line level input may
be suitable. Ensure that the left and right channel sense are
correct between the tuner and the amplifier.
Connection of an External Aerial
This socket
2
is for use with a 75Ω external FM aerial.
The quality of the aerial you use will directly affect the
performance of your tuner. We would therefore advise
that you contact an aerial installation expert in your local
area or consult your dealer. In areas where FM cable
transmission is available the signal strength should be
generally quite adequate.
MC-BUS System Connection
This is an optional connection
3
which enhances and
expands the capability of specific Cyrus products,
including your FM7. Through the MC-BUS and certain
ancillary equipment a highly functional integrated system
with full remote control ability may be set up.

Cyrus FM7 OPERATION
POWER
The mains power switch
4
is located on the rear panel of
the tuner (refer to figure 1, rear panel drawing on page 4).
This switch should be left on for normal operation, except
when left unattended for a long period. In this case the
mains power should be switched off or the product
disconnected from the AC supply.
Refer now to figure 2, front panel drawing on page 6.
When the tuner is in regular use and power is permanently
applied, the STANDBY key
7
can be used to switch the
unit on and off. The standby light will show red when the
tuner is in standby and green when operating. The FM7
will also switch on if a preset station is selected.
SELECTING A BROADCAST STATION
To stop scanning press the SEEK key.
Manual Tuning
Manual tuning can be used to set to a known station
frequency or to lock to a weak transmitter, not detected in
auto tuning. Rotate the MANUAL tuning control
4
until
the required frequency is shown on the frequency display.
The frequency will change in steps of 0.1MHz, which is
the standard broadcast channel spacing for FM
transmission. When a station is correctly tuned to, the lock
indicator will be displayed. The signal strength can then
be read from the bargraph display (refer to page 9 for
detail).
Auto Tuning
Auto tuning will search automatically for stations with a
usable signal strength. To begin searching, press the
SEEK key
6
and the tuner will scan up the frequency
range, locking to the next available station. Another press
will continue station scan. The station frequency and
signal strength can be read from the display. If the station
detected is already stored as a tuner preset, the preset
location will also be shown on the display.

OPERATION Cyrus FM7
FINE TUNING A BROADCAST
Certain commercial radio stations and some cable
broadcasts are prone to imprecision in their transmitted
carrier frequency. This may cause distortion and will
detract from ultimate sound quality. In such instances and
for precise station alignment, fine station tuning is made
available.
Fine Tuning
To fine tune a broadcast station, first locate your station
using either AUTO or MANUAL tuning. Ensure that the
lock indicator on the display is showing. Press the FINE
key
2
. Now the manual tuning control can fine tune the
station in steps of just 10kHz. Whilst fine tuning, the
bargraph display switches to show a "magic eye" tuning
meter. For precise station tuning the black bars on each
side of the display should be of equal length. Press the
FINE key again to cancel fine tuning mode. Note that fine
tuning will cancel automatically if no adjustment is made
within a 5 second period. For more detail on fine tuning
refer to page 10.
PRESET STATION STORAGE
Seven preset memories are readily available on the front
panel which may be programmed with your favourite
stations.
Storing a Preset Station
To store a preset station, first locate the station using
either AUTO or MANUAL tuning methods as described
before, followed by fine tuning if necessary. Press and
hold a PRESET key for about two seconds until the
display blinks. The station is now stored in this preset
location. The memory of the FM7 will retain preset
stations indefinitely and requires no back up-batteries.
Note that the same station stored in two locations will
always show the lowest preset number on the display
indicating double storage of the same frequency. In this
case one of the preset locations can be re-programmed.
Tuning to a Preset Station
To recall a station from the preset memory, press the
desired PRESET key briefly. If no station is present, the
frequency digits will read zero and the search arrows will
flash briefly.

ADDITIONAL INFORMATION Cyrus FM7
µ
KNOW YOUR
FM7
The Bargraph
The signal strength bargraph and "magic eye" tuning
indicator of the FM7 can be used for accurate assessment
of signal quality at the antenna terminals. At Mission, our
automated test procedure enables each segment of the
display bargraph to be individually calibrated for signal
strength and tuning deviation. The calibration data is then
stored in a digital memory for recall each time power is
applied to the tuner.
When reading signal strength, the bargraph reads from 20
dBµV to 60dBµ V in 2dBµV steps.
Optimised Fine Tuning
De-tuned + 30kHz De tuned - 40 kHz
The Frequency Display
The FM7 frequency display will always read the
published nominal station frequency. An exception to this
is when fine tuning is selected when an extra digit
displays 10kHz steps for ultra accurate tuning. This can
now be stored.
When this station is selected the FM7 will display the
rounded frequency to match the advertised nominal
frequency.
Other Features
The Signal Meter Scale (dB
V)
When set for fine tuning however, the bargraph will
indicate station deviation in steps of 10kHz (two segments
per step). The following illustrations show different
examples of tuning alignment.
English
10
The FM7 is equipped with a high performance active pilot
tone suppression circuit. This ensures superb rejection of
subcarrier related spuriae, whilst providing a direct path
for audio signals.
Four power regulators supply the RF, PLL, Audio and
Control circuit modules of the FM7 independently.

turned on.
No Display
• If you have a remote handset, then press the
DISPLAY key to turn the display on again.
FM7
will not Tune to Stations in SEEK Mode
• Make sure that the antenna is connected to the
75Ohm socket on the rear panel and that stations can
be tuned manually.
All Stations have High Background Noise
• Check the correct connection of your antenna. If the
problem persists there may be a bad connection in
the antenna connector.
Some Stations have High Background Noise
• These may be weaker or more distant stations and
therefore may require adjustment to the antenna
direction for optimum reception.
• Do bear in mind that there is a big difference in the
sensitivity of FM antennae available on the market,
and that your current antenna may need upgrading.
• Proximity to appliances with potential for high
frequency radiation may cause interference with high
quality reception in certain frequency bands. If you
own CD players, computers and similar devices
experiment by removing them from the mains and rechecking the noisy station.
No Stereo Indication
• Check other stations for stereo reception. the
particular broadcast may be in mono. For example
speech, commentary, etc.
