1. Press the power switch on the headphone, the LED indicator will illuminate.
2. If the headphone is receiving a signal, the LED indicator turns on, if there is no reception the
indicator just blinks once as an indicator for no signal.
3. If the LED indicator does not blink or light up, change the batteries behind the battery cap.
4. Adjust the volume control to the desired level.
5. For using the headphone in a wired configuration, connect the jack 3.6mm audio connector
to the headphone. While using the headphone wired it works without the batteries.
The SILENT DISCO BOX HD8-BLACK wireless headphone is specially developed for intensive use for
silent entertainment. The structural virtue and straightforward controls are clear characteristics of a
specified design. The headphone has three pre-programmed RF channels, which are easy recalled
with the control switch. Besides the RF channel selection, the headphone is equipped with a volume
control and a power switch. Each headphone operates on a pair of AAA batteries for about 10 hours.
The cushion in the head band makes a tight but comfortable fit which makes the headphone
wearable for children from eight years old and up.
Quick Start.
The wireless headphone is equipped with a Phase Lock Loop (PLL) and Micro Computer (MCU)
system,
providing the ultimate frequency stability.
With the Active Noise Reduction Technology the background “hissing” noise (that sometimes occurs
during a silent break) is virtually eliminated.
If no signal is received by the headphone, it will immediately mute at once.
After 3 to 5 minutes without signal the headphone will turn its power off, saving the battery.
