Reference Tuner-1.0

AERIAL REQUIREMENTS

The tuner aerial should be mounted on the roof, clear of obstructions and also as high as possible. Horizontally
polarised aerials will respond to almost all commercial broadcasts whilst partially rejecting police and taxi
transmissions, and are therefore recommended. Use of an aerial preamplifier will disturb the muting operation of
the tuner and may cause cross modulation problems. Such preamplifiers should only be used as a last resort.

In most commercial radio broadcasts are usually radiated from different sites even though the target areas of the
services may be similar. This means that unless the transmitters are in almost the same direction looking from
your house, an aerial aligned on one transmitter will give less than optimum performance on the other. In these
circumstances you should fit an aerial rotator, or a less directional aerial if appropriate. The more sensitive and
directional the aerial you use, the less good will be the reception in directions other than the one towards which
the aerial is pointing. If you are particularly interested in receiving a wide range of VHF transmissions an aerial
rotator is a necessity. Your dealer will be familiar with local conditions and will be able to advise you on which
stations are capable of being received satisfactorily.

CONNETIONS

The FM aerial input socket could be connected via 75ohm low-loss coaxial cable to a suitable roof-mounted
directional aerial. The tuner’s audio output is set to 700mV at 100% modulation and should match almost any
preamplifier without difficulty.

GENERAL USE

FRONT PANEL OF TUNER

The Tuner has only seven buttons. The buttons on the front panel have 7 functions.

POWER ON OFF

2

The Tuner is switched on by pushing the power button q on the left hand side of the front panel. A flashing "
TUNER TU-902" blue light in the display indicates that power has been switched on. And then goes to factory set
“FM 87.5MHz” and stand-by for modulation.

By pushing the same button one more time the power is switched off and stay at the final choose station till the
next turn on. To cancel all the memory v and get back the factory set, push the memory clear key on the remote
5 seconds.

FM / AM

Pushing the FM/AM button s on the front panel or on the remote will switch the tuner sequentially through “FM”
and “AM ” modulation modes.

STEREO / MONO

Pushing the STEREO/MONO button w on the front panel or st. /mono key on the remote will switch the tuner
sequentially through “stereo” and “mono ” modes.

FM programmes which are broadcast in stereo recommended stereo mode except those which are extremely
weak or in circumstances of very weak reception, when mono operation will be enforced because stereo
reproduction would be too noisy. Mono mode combines the left and right channels to produce a mono output
signal. Switching to mono can reduce background noise with weak stereo signals.

AUTO / MAN

Pushing the AUTO/MANU button (11) on the front panel or auto/man key on the remote will switch the tuner
sequentially through “auto-scan” and “manual ” modulation modes.

In manual modulation mode, the tuning knob on the front panel or up and down navigator keys on the remote
could adjust the tuning frequency step by step. In auto-scan modulation mode, the tuning knob on the front panel
or the up and down navigator keys will cause the tuner to search for stations automatically.

TUNING

In manual modulation mode, adjusts the tuning knob clockwise or counter-clockwise or push the up or down
navigator keys on the remote continually searching for signals and stations. Rock the tuning knob tslightly
backwards and forwards to check that the tuning is set to the center of the range over which the station can be
heard, or the station may slip off tune.

In auto-scan mode, causes the tuner to “scan” down the FM/AM band searching for signals above a preset level.
The tuner will stop searching at each tuned station and, using the remote, the option to store the station as a
preset will be available. During tuning automatically, the tuned frequency display on the screen r until a station is
received and tuned with sufficient accuracy.

MEMORY

The stations memory key enables specific FM station frequencies to be assigned to preset memory. To assign a
station to a preset first tune manually by inputting the station frequency directly from the numeric keypad or by
using the up or down navigator keys (or auto-scan ). Press the stations memory key on the remote, the tuner is
now in station memory mode-the “MEM” indicator will flash and the display will show “- -” or numbers of station.
Press the desired preset number (00-39) from the numeric keypad or choose the desired preset number (00-39)
by using the tuning knob on the front panel or the up or down navigator keys on the remote, then press one more
time the stations memory key simply.

MUTE

Push the MUTE button, a flashing" MUTE" blue light in the display indicates ureducing the tuner output volume
to zero. A second press restores the volume.

ADDITIONAL FUNCTION AVAILABLE ON THE REMOTE CONTROL

CLOCK / TUNER

Switch the tuner sequentially through “clock display or time reset ” and “tuner ” modes.

NUMERIC KEYPAD

In tuner mode the numeric keys will select tuner presets or can be used directly to input station frequencies.

AUTO SCAN-SAVE

Press the scan-save key on the remote, the tuner is now in auto scan-save stations mode. Turn slightly the tuning
knob a bit clockwise/counter-clockwise or push once the up or down navigator keys on the remote, the tuner to
“scan” down the whole FM band searching for signals/stations and store them automatically.

FREQUENCY INPUT AND PRESET

Press the freq.input key once on the remote, the tuner is now in frequency input preset mode-the display will
show “- - -”. Then input the station frequency directly from the numeric keypad to tune manually.

TIME SET

Toggles the tuner through three time set modes – turn on time, clock time and turn off time.

BRIGHTNESS OF DIGITAL INDICATOR
Toggles the tuner display through three brightness modes – bright, light and dim.
MEMORY CLEAR

To clear the memory of preset stations press the memory clear key, the Indicator shows “clear” and with flash of
the preset stations number you want to clear, then followed by the enter key on the remote.
