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.

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.

Power Supply
The transmitter can operate on two LR6 (size AA) alkaline
batteries continuously for about 6 hours at 25°C (77°F).
Inserting the batteries
Battery indication
When you turn the power on, the battery status appears in
the BATT indication on the liquid-crystal display.
Promptly replace both batteries after reaching stage 3
shown in the table.
The indication may be incorrect if the batteries are not new
when inserted. If you plan to use the transmitter for a long
period, it is best to replace the batteries with new ones.
Notes on batteries
•The BATT indication on the WRR-850A starts flashing
earlier than that on this transmitter.
•Use new alkaline batteries of the same type, and check the
recommended “useby” date on the bottom of the batteries.
•Be careful to insert the batteries with the correct polarity.
•When not using the transmitter for a long period, remove
the batteries to avoid leakage. If a battery does leak, clean
all leakage from the unit and insert new batteries. Leakage
left in the unit may cause poor battery contact. If there
seems to be poor battery contact, consult your Sony dealer.

1While holding down the SET/DISPLAY button, set the
POWER switch to ON.
Hold the SET/DISPLAY button down until a display
appears.
The transmitter goes to setting mode and the indication
on the liquid-crystal display flashes.
If the channel or time-of-use indication had been
selected before the transmitter was previously turned
OFF, the channel indication flashes (channel number
selection mode). If the frequency had been selected, the
frequency indication flashes (frequency selection mode).

Operation
If you keep either button pressed, the channel setting will
be incremented or decremented successively.
The setting will cycle the channel from 68-01 through
69-47.
3Once the desired channel number (or frequency) appears,
set the POWER switch to OFF to release setting mode.
The next time you turn on the power only by setting the
POWER switch to ON, the transmitter will be set to
transmit mode with the selected channel.

Notes
•The unit cannot transmit in setting mode.
•Make sure that the channel selected is the same as that
selected on the tuner used in the same system.
•Depending on the noise or interference conditions, the
selectable channels may not necessarily all be usable. If
necessary, you can determine the usable channels by
stepping the channel selection through a number of
channels on a tuner with the transmitter set to OFF.
Those channels on which the RF indicator of the tuner
does not light are usable.
•If there is a TV broadcasting station near by, do not use
the station's channel.
•The unit may not operate correctly if it is turned on again
immediately after turning off the power while in setting
mode. Pause for a few seconds or more before turning on
the power again.

Notes on Microphone System Operation
•To operate with 2 or more channels, maintain a distance
of at least 30 cm (1 ft.) between each pair of transmitters.
For details of operation with 2 or more channels, refer to
the Operating Instructions for the WRR-810A UHF
Synthesized Tuner and WRR-820A/840A/850A/860A
UHF Synthesized Diversity Tuners.
•Ensure that the tuners set to channels not being used are
either turned off or set to the minimum output level.
•When powering the transmitter on or off, to keep the
noise to a minimum, set the audio output level from the
tuner or mixer to a minimum.
•Powering the transmitter on without checking the channel
selection first may interfere with the operation of other
microphones/transmitters, if the current setting is already
being used.
Operation
Changing in transmit mode
You can also change the input attenuation setting during
transmission.
1When the attenuation setting is indicated on the display,
press and hold the SET/DISPLAY button for more than
1 second.
The ATT indication flashes.
2Press the + or – button to select the attenuation setting in
the same manner as in setting mode.
3Press the SET/DISPLAY button.
The ATT indication stops flashing.
(Or leave the unit without pressing any button for more
than 5 seconds. The flashing automatically stops and
normal transmit mode is resumed.)
