English
On operation
•The tuner must be used within a temperature range of
0°C to 40°C. Avoid using the tuner for extended
periods at extremely high temperatures or placing it
in direct sunlight, especially outdoors, because this
may damage the finish of the case. Never install the
tuner on or near a heat source, such as lighting
equipment or power amplifiers.
•Avoid using in very humid or dusty places, because
such use may shorten the life of the tuner.
•To avoid degradation of the signal-to-noise ratio, do
not use the tuner in noisy places or in locations
subject to vibration, such as the following:
– near electrical equipment, such as motors,
transformers or dimmers
– near air conditioning equipment or places subject
to direct air flow from an air conditioner
– near public address loudspeakers
– where adjacent equipment might knock against the
tuner
•Switching lights on or off may produce electrical
interference over the entire frequency range. Position
the tuner and the wireless microphones so that
interference is minimized.
•The tuner is precisely adjusted at the factory and no
adjustment before use is necessary. Do not touch the
inside of the tuner or try to repair it by yourself.
On cleaning
Clean the tuner with a dry, soft cloth. Never use
thinner, benzene, alcohol or any other chemicals, since
these may damage the finish.

System Configuration
The tuner can be used with a Sony UHF synthesized
wireless microphone or UHF synthesized transmitter
among the models listed in the table below.
Sony 800 MHz-band system models
Channel Plan
The tuner stores several groups of channels. See
“Overview of Channel Plan” in the “Wireless Channel
Lists” section.
Channel groups other than group 00 are designed so
that all channels of one group can be used
simultaneously within the same UHF wireless
microphone system without causing intermodulation.
It is therefore recommended that you usually use a
channel group other than group 00 unless the use of
group 00 is specifically necessary.
Note
To eliminate interference or noise, please note the
following.
•Do not use two or more wireless microphones or
transmitters whose wireless channels are the same.
•If there is a TV broadcasting station nearby, to avoid
possible interference from its broadcasting, do not
use that station’s channel.
•The number of wireless microphone channels
actually usable in a multi-channel system may be
smaller than the normal capacity of that system if
there is interference from TV broadcasting or other
RF signals.
•When operating two or more UHF wireless
microphone systems using the same wireless channel
in the same group, ensure that the systems are at least
100 m1) apart as far as they are installed within sight
of each other.
1) The distance depends on the operating environment and
conditions.

If noise is heard
Depending on the environment where the system is
installed, outside noise or radio wave may disrupt the
transmission of certain channels.
To select a channel under this circumstance, turn off
the wireless microphone and transmitter. Then select a
channel at which the RF indicator is off. (A channel
free from noise or radio wave interference is selected.)
Muting Functions
This tuner has the following three muting functions,
which work in combination.
(1) Muting by RF input level
As sufficient S/N for the audio output may not be
obtained if no RF signal is received or the RF input
level is low, the audio output can be muted when the
RF input level falls below the muting level.
(2) Tone squelch
The audio output is obtained only when the tuner
receives an RF signal which includes a specified tone
signal. The audio output is muted to eliminate noise
which may be heard when the transmitter is turned on/
off or the tuner receives an interference RF signal.
(3) Noise squelch
The audio output is muted to eliminate noise which
may be heard when there is such excessive interference
RF signal that the tone squelch does not work.

Kanalplan
Es können mehrere Kanalgruppen gespeichert werden.
Siehe „Überblick über die Kanäle“ in Abschnitt
„Übertragungskanallisten“.
Bei den Gruppen 01, L und H sind die Abstände
zwischen den Kanälen so groß, daß auf allen Kanälen
ein simultaner Betrieb von UHF-Mikrofonen möglich
ist, ohne daß es zu Interferenzstörungen kommt. Die
Gruppe 00 bietet zwar die größte Anzahl an Kanälen,
sie sollte jedoch nur dann verwendet werden, wenn es
unbedingt erforderlich ist.
Hinweis
Zur Vermeidung von Interferenzstörungen beachten
Sie bitte die folgenden Punkte:
•Betreiben Sie nicht gleichzeitig zwei oder mehr
Mikrofone bzw. Sender auf demselben Kanal.
•Meiden Sie Kanäle, auf denen starke TV-Sender
arbeiten.
•Bei einem simultanen Mehrkanalbetrieb können
eventuell nicht alle Kanäle verwendet werden, da auf
einigen Kanälen Interferenzstörungen von starken
TV-Sendern oder anderen starken HF-Signalen
auftreten.
•Wenn zwei oder mehr UHF-Mikrofonsysteme auf
demselben Kanal derselben Gruppe senden, sollten
sie mindestens 100 m1) entfernt voneinander sein.
