Installation setting up the tuner =
Accessories included The tuner is fitted with a fixed power cable and
a plug of the type used in your country, If the
contents are incorrect, please consult your
dealer.
Set up your tuner in a position where there is a
clearance of at least 10mm (inch) from
other equipment, walls and furniture.
Setting up the tuner
Safety precautions Connect the tuner to the AC outlet only by
means of the fitted power cable.
Always keep the tuner in dry condition. Itis ex-
tremely hazardous to operate it in moist con-
ae (bathroom, laundry room, basement,
etc.
The tuner is not disconnected from the AC
power source when it is switched off (stand-
by). Certain components inside the unit are al-
ways energized with line voltage!
The tuner is designed to be operated in a hori-
zontal position.
In case of amalfunction or a defect,immedia-
tely disconnect the power plug and have the
tuner checked out by an authorized REVOX
dealer.

Power on
Make sure that the voltage rating imprinted
below the power inlet corresponds to your
local line voltage.
The tuner can be altered to a different line vol-
tage but this work should be performed by
your dealer.
You can connect two antennas (A [33] and B
{34]) with 75 Ohm coaxial cables to your tun-
er. Both sockets have identical functions.
If you have access to a local cable network,
connect the antenna socket A [35] tothe an-
tenna outlet by means of commercially avail-
able antenna cable. In addition you can con-
nect an external antenna or a room antenna to
the other socket B [34] so that programs can
be received that are not transmitted via the
network.
The ideal site for external or room antennas
can be determined by experimenting.
The audio (signal) outputs AUDIO L/R [35] are
to be connected to the TUNER inputs of your
amplifier (REVOX B250-S). Do not confuse
the left-hand (L) and right-hand (R) channels.
Press the POWER [1] key on the front panel to
switch on the FM tuner. The station memory
that was active when the tuner was previously
switched off is automatically reactivaied.
When you press the POWER [1] key again, the
tuner switches off (standby).
When the tuner is switched off but si fl con-
nected to the AC power source, it operates in
standby mode which means that it can be
conveniently switched on and off by means of
the REVOX B208 iR remote control from your
listening position. The power consumption in
standby is negligible (approx. 5 W).

When the station frequency is known (from
program guides or frequency schedules), the
frequency can be set directly by means of the
numeric input keys [7].
The TUNING [14] key activates the mode for
searching station frequencies. The display
[11] shows only the frequency and the step
width.
Enter the desired frequency by means of the
numeric keys [7].
The microprocessor checks instantly that the
entered value falls within the available FM fre-
quency band and rejects incorrect entries.
In the event of an error, an asterisk (*) appears
onthe display [11] which means that the entry
must be repeated with valid digits.
The entered frequency is set and the station
becomes audible. After any corrections of the
reception parameters (see modification of re-
ception parameters), the entered frequency
can be saved in a station memory.
This is the preparatory step for storing the fre-
quency. The station frequency flashes on the
display [11].
Enter the number of the station memory by
means of the numeric keys [7].
The frequency and the reception parameters
are stored in the specified station memory.
Instead of performing the last three input
steps (STORE, numeric keys and ENTER) you
can simply press the AUTO [29] key. The fre-
quency and the reception parameters vill au-
tomatically be stored in the next vacantstation
memory or the next station memory with pro-
gram identification 0.

You can increase (>) or decrease (<) the tun-
ing frequencies in steps according to the se-
lected channel pattern (10kHz/50kHz) by
pressing the STEP [15] key. In this way you
can receive stations that broadcast on a fre-
quency that is outside the 50kHz channel
pattern.
The tuner can be tuned exactly to the station
frequency with the aid of the center channel
indicator on the LC display [19]. Tuning is cor-
rect when the two symbols + and - are simul-
taneously visible. If only one of these sym bols
is displayed, the tuned frequency should be
shifted in the direction of the arrow.
If you are tuning to a station that does not
broadcast on a frequency of the 50 kHz chan-
nel pattern, you can press the STEP[15] key to
switch the step width to 10 kHz (channel pat-
tern = frequency spacing in kHz of the indivi-
dual stations). Press this key again to switch
back to the 50 kHz channel pattern.
The selected channel pattern is shown on the
display [11] in place of the station number.
In AUTOTUNING mode the tuner always
scans in the 50kHz channel pattern, even
when the 10 kHz step width has been selected.
For stations that broadcast on a frequency
outside this channel pattern, the frequency at
which the scan stops will be off center. You
can manually tune this frequency by pressing
the FREQUENCY STEP [3] key until the indica-
tor on the LC display [19] signals that center-
channel tuning has been achieved.

abbreviation, program identification, and re-
ception parameters) is very simple.
This recalls the memory to be copied.
This is a preparatory step for the store opera-
tion.
Enter the memory location into which the in-
formation is to be copied.
Caution:
The old content of this memory will be lost be-
cause it is overwritten by the new information
to be copied.
The selected station memory is overwritten
with the data of the other memory.Both me-
mories now contain identical data.

In tuning mode (TUNING [14] key pressed},
you can switch between local and distant
muting thresholds by pressing the SEARCH
[17] key.
In the LOCAL position (indicated by an arrow
on the display), the search threshold is 100 pV
which means that only strong stations will be
selected.
In the DISTANT position the search threshold
is 4uV so that also weak, distant transmitters
will be selected.
The third position, IDENT, can only be activat-
ed in conjunction with the RDS option and
enables you to search based on matching sta-
tion identification.
With the ANTENNA [22] key you can switch
between the two antenna inputs A and B. The
currently active antenna input is identified on
the LC display [19] by the corresponding let-
ter.
With the RF [20] key you can change the RF
selection (RF PRE-TUNING) between SINGLE
and DOUBLE. Two arrows on the LC display
[19] signal the corresponding selection.
Normally the tuner is operated in SINGLE
mode because it ensures maximum sensitiv-
ity of the antenna input.
For better selection of strong stations without
interference from adjacent channels,
re aio reduces the antenna sensitivity by
4 cB.
With the IF [24] key you can change the IF
BANDWIDTH between WIDE and NARROW.
Two arrows on the LC display [19] signal the
corresponding bandwidth.
Normally the tuner is operated in WIDE mode
(150 kHz bandwidth) because it ensures mini-
mal harmonic distortion.
For better adjacent channel selectivity the
NARROW (110 kHz bandwidth) setting can be
used.
