WRR-802A (U)

Apart from the normal indications, the following error
messages may appear on the display.

Meaning

Remedy

Err 01

Message

An error has occurred in
the backup memory data.

The memory data is
initialized. Reset the
group and channel
settings.

Contact your nearest
Sony dealer.

The PLL-synthesized
circuit has a malfunction.

Err 02

NO TONE

As no tone signal is
available or a tone signal
other than 32.768 kHz is
being received, the audio
signal output is muted.

Make sure that the
transmitter is turned on.
If it is, then the problem
lies in the transmitter’s
tone signal generator or
the tuner’s tone squelch
circuit. Contact your
nearest Sony dealer.
If you are using a WRT-
810A wireless
microphone, a “NO
TONE” message
appears when you turn
off the AF switch, but
this is normal.

Muting Functions

This unit 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 unit 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 unit 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.

To turn off the muting functions

While holding down the GP and CH buttons, turn the POWER
switch to ON. All indications momentarily appear, then go off.
“OFF” is then displayed. This procedure cancels all three
muting functions at the same time.

To turn on the muting functions

Turn the POWER switch to OFF, then to ON again. The three
muting functions are activated at the same time.

Guidance on use of multi-channel system

This product is designed to give excellent interference free
operation in multi-channel systems. To maintain this, Sony
recommends that one of the original Sony groups, number
00, 11, 12, 13, A1, A2, A3, L1, L2, H1 or H2 is selected.
These groups will offer excellent performance, free from
mutual interference from other Sony wireless microphone
transmitters in the selected group when used under the
recommended operating conditions. The remaining groups
are included for compliance with frequency regulations in
various countries, and will not always guarantee interference
free operation.
Group 00 is used to scan for open channels, or to use only
for a one channel system.

Directrices para el uso de sistemas multicanal

Este producto se ha diseñado para proporcionar una
operación excelente sin interferencias en sistemas de
múltiples canales. Para esto, Sony recomienda seleccionar
uno de los grupos originales de Sony, es decir, los número
00, 11, 12, 13, A1, A2, A3, L1, L2, H1 o H2.

Estos grupos ofrecen un funcionamiento excelente, sin
interferencias en ambos sentidos con otros transmisores de
micrófono inalámbrico de Sony del grupo seleccionado,
siempre que se utilicen en las condiciones de
funcionamiento recomendadas. Los demás grupos se han
incluido por motivos de compatibilidad con las normas
sobre frecuencias de varios países y no siempre garantizarán
un funcionamiento sin interferencias.
El grupo 00 sirve para buscar canales abiertos o se utiliza
solamente para sistemas de un solo canal.

Guide d’utilisation du système multicanal

Ce produit est conçu pour assurer un excellent
fonctionnement exempt d’interférences dans les systèmes
multicanaux. A cette fin, Sony recommande de sélectionner
l’un des groupes Sony originaux portant les numéros 00, 11,
12, 13, A1, A2, A3, L1, L2, H1 et H2.
Ces groupes offrent d’excellentes performances, exemptes
d’interférences mutuelles avec d’autres emetteurs de
microphone sans fil Sony dans le groupe sélectionné s’ils
sont exploités dans les conditions d’utilisation préconisées.
Les autres groupes sont inclus pour satisfaire aux
réglementations sur les fréquences dans les différents pays
et ne garantissent pas toujours un fonctionnement exempt
d’interférences.
C’est le groupe 00 qui est utlilisé pour explorer les canaux
ouverts, ou en vue de l’utilisation d’un système à canal
unique.
