Features - Sony WRT-860A Operating Instructions Manual

Features

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.
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.
