Notice for customers in Canada:

Use of Sony wireless devices is regulated by the Industry

Canada as described in their Radio Standard Specification

RSS-123.

A licence is normally required. The local district office of

Industry Canada should therefore be contacted. When the

operation of the device is within the broadcast band, the

licence is issued on no-interference, no-protection basis with

respect to broadcast signals.

Avis pour les clients au Canada:

L’usage des appareils sans-fil Sony est réglé par l’Industrie

Canada comme décrit dans leur Cahier des Normes

Radioélectriques CNR-123. Une licence est normalement

requise. Le bureau de l’Industrie Canada doit être contacté.

•The unit is designed for use in ambient temperature range

of 0°C to 50°C (32°F to 122°F).

•Do not place the unit on or near heat sources, such as

lighting equipment, power amplifiers, or in a place

subject to direct sunlight or excessive moisture. In such

places, the external finish or internal parts of the unit

may be damaged.

•If the unit is used in a very humid or dusty place or in a

place subject to an active gas, clean its surface as well as

the connectors with a dry, soft cloth soon after use.

Lengthy use of the unit in such places or not cleaning it

after its use in such places may shorten its life.

•When cleaning the unit, never use organic solvents such

as thinners or benzine, which will damage the finish of

the unit.

•The unit has been factory adjusted precisely. Do not

tamper with its internal parts or attempt to repair it.

The WRT-860A is a transmitter for an 800 MHz band UHF

synthesized wireless microphone system to be used for

broadcast or movie production purpose.

The other system components include the WRT-810A/

830A/867A UHF Synthesized Wireless Microphone, the

WRT-820A UHF Synthesized Transmitter, the AN-820A

UHF Antenna, the WD-820A/880A UHF Antenna Divider,

the WRR-810A UHF Synthesized Tuner, the WRR-820A/

840A/850A/860A UHF Synthesized Diversity Tuner.

The microphones/transmitters and tuners are classified by

frequency band. See the table to the right.

A 12 MHz frequency band (or two consecutive numbered

TV channels) is assigned to each microphone/transmitter

and tuner model. To indicate the assigned frequency bands,

the parenthesized numbers following the model names in

the table show the smaller of the assigned TV channel

numbers.

Introduction

Sony 800 MHz band system models

a) For these models, the AN-820A UHF Antenna is required. Use the

WD-820A/880A UHF Antenna Divider in addition when required.

Features

CPU and LCD for coordinated operation control

The built-in CPU controls operation of the unit, including

the PLL circuit function. The LCD shows the current

channel number, the residual battery power, input

attenuation setting, AF input level and RF output.

An accumulated operation time indication is also provided

for simple control of the time of battery use (in 1-minute

increments).

Saved channel and input attenuation settings

The unit stores the channel and the input attenuation setting

when it is turned off. The saved settings are retained even

if the batteries are removed. Therefore, when using the unit

next time, you need not make the same settings again.

Highly reliable electronic attenuator

The built-in input level attenuator is adjustable in a range of

0 to 30 dB in 3-dB steps. It reduces signal distortion when

an excessively strong input signal is received.

RF carrier with tone signal

The unit transmits the RF carrier accompanied by a tone

signal, enabling the tuner with a tone squelch circuit to take

out only the target audio signal received.

Wide dynamic range and low noise

The compander (compressor/expander) system enables

transmission over a wide dynamic range with minimum

noise.

Easy selection of 94 channels

With its sophisticated phase locked loop (PLL) circuit, the

unit can operate on any one of 94 carrier frequencies

selected by a simple button operation.

Compact and lightweight

Innovative, high-density mounting technology has enabled

the creation of this compact and lightweight transmitter,

which lets you move anywhere for Electronic News

Gathering (ENG) and Electronic Field Production (EFP).

Battery status information

This transmitter has capability of transmitting “Battery

status information” to the WRR-850A.

The information is sent to the WRR-850A in approx. 1 hour

advance to battery exhaust so that they can safely replace

batteries of the transmitter.

When the WRR-850A receives the information, the LED

and the LCD on the panel start flashes.

Operation powered by easily available batteries

The built-in DC-DC converter allows stable operation, for

about 6 hours continuously, with just two LR6 (size AA)

alkaline batteries.

The WRT-860A can transmit on any selected wireless

channel among those listed below. For channel selection, see “Changing the Channel

Selection” on page 13.

When you mount the transmitter in the supplied soft case,

you can easily fix it to your clothing on your belt, etc. with

the clip of the case. If it is more convenient to fix the unit

with the antenna downwards, mount the transmitter in the

case upside-down.
