Notes

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 broadcast, do not use that station’s channel.

•The number of wireless 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.

•To operate two or more UHF synthesized wireless microphones/transmitters using the same wireless channel of the same group, ensure that the wireless microphones/ transmitters are at least 100 m (330 feet)1) apart as far as they are installed within sight of each other.

•When using two or more WRR-855A/855Bs, do not directly put one unit upon the other.

Settings

Interference-check function

Before operating a wireless microphone or transmitter, you can check for possible interference by using the interference-check function of this unit. To check the interference, simultaneously press the + and – buttons in the channel selection mode (the channel number flashes). The channels of the selected group are automatically switched one by one in sequence (this operation is called “scanning”).

Notes

•When the MUTING switch is ON and the unit is not in the T OFF mode (see page 13), scanning stops and the channel at that time is selected if a tone signal (32.768 kHz) is detected in the signal received during scanning.

However, scanning will not stop if a interfering signal having no tone signal is received.

In this case, check for the interference by observing the RF input level indicator.

•Scanning is automatically cancelled when all the channels of the selected group are scanned twice. To cancel scanning in progress, press any of the operation buttons.

•If an extremely strong signal is received, scanning may stop at a point other than the actual channel.

Setting and Releasing the T (Tone

Squelch) OFF Mode

The WRR-855A/855B 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 selected 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.

Only the muting functions described in (2) can be canceled by selecting the Tone-squelch OFF (T OFF) mode when desired. Apply this mode when you use a transmitter with no specified tone signal.

12(GB)

Selecting the T OFF mode

1 Turn the power ON while pressing and holding the GP and – buttons.

2 On the WRR-855A, release the buttons after the “HELLO” message appears. On the WRR-855B, release the buttons after the version number of your tuner (for example “U66”) appears.

“T OFF” is momentarily displayed and the tuner goes to the T OFF mode.

The T OFF mode is maintained even when the power is turned OFF.

Cancelling the T OFF mode

1 Turn the power ON while pressing and holding the GP and + buttons.

2 On the WRR-855A, release the buttons after the “HELLO” message appears. On the WRR-855B, release the buttons after the version number of your tuner appears.

“T ON” is momentarily displayed and the tuner resumes the normal status.
