Precautions • The tuner must be used within a temperature range of 0°C to +50°C (+32°F to +122°F). Avoid using the unit for extended periods at extremely high temperatures or placing it in direct sunlight, as 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. -

Page 25: Setting The Muting Level
The RF lamp lights up whenever signals above 15dB µ are detected in the frequencies within the wireless channels receivable on Sony receivers. The scanning will also stop on any frequency containing a tone signal of 32.768kHz, provided the RF signal is stronger than the set muting level. - Page 26 Sony wireless microphone system. The moment a transmitter is turned on or off, it does not transmit the tone signal on the RF carrier, and this function enables the WRR-850A to squelch noise caused when a transmitter is switched on or off. It is possible to operate the WRR- 850A together with a transmitter which has no tone signal if the tone signal squelch circuit is turned off.
