1. INTRODUCTION
The Digital Wireless Headphone System consists of a 5.8 GHz transmitter and 5.8 GHz
headphones. The transmitter features three audio inputs and a pilot microphone input. The pilot
microphone input will override the other inputs when active. The unit is designed to integrate into
any entertainment system with analog audio capability.
This guide describes general configuration information for the Rosen Wireless Headphone
Transmitter with any audio source equipment to supplement the Outline & Installation Drawing
(P/N 0700-010-CD).
Note: Only trained and qualified personnel should perform installation and service.
1.1. Unpacking
The parts shipped with the 5.8 GHz Digital Wireless Transmitter include:
One 5.8 GHz digital audio transmitter (P/N 0700-010)
One connector kit (P/N 0300-043)
The parts shipped with the 5.8 GHz Digital Wireless Headphones include:
One set of 5.8 GHz Digital Wireless Headphones (P/N 0500-101)

4. PLACING THE TRANSMITTER
The wall-mounted transmitter must be mounted with the J1 connector pointing toward the ceiling
of the aircraft cabin. It can be placed behind a bulkhead or other wall, as long as the bulkhead or
wall is made of composite or wood material.
Figure 1 Digital wireless headphone transmitter
For acceptable performance, the transmitter is to be mounted so that the antenna is aligned along
the aircraft longitudinal axis. The optimal installation is with the transmitter in the front of
passenger seating pointing aft.
Install transmitter so that
J1 connector points
toward aircraft ceiling
This is the antenna face. For best results,
the transmitter will be wall-mounted in
front of passenger seating with the
antenna facing aft.

There are two battery compartments, one in each earpiece.
1. To open the battery compartment, press the center of outer edge of either earpiece
firmly –the battery compartment lid will pop open.
2. Insert the battery by pressing the bottom of the battery down against the spring at the
bottom of the battery compartment. The battery should snap into place.
3. To remove the battery, pull the top of the battery down against the spring at the
bottom of the battery compartment.
4. Close the battery compartment by pushing the middle section of the lid.

6. OPERATING THE HEADPHONES
The aircraft must be powered up before the headphones will function. Set the volume control of
the headphones to minimum. Press the power button on the headphones. Once the headphones
detect a signal, the LED indicator on the headphones will turn green and the transmitter will
transmit the audio signal. If no signal is detected, the LED indicator will be red.
Turn on the headphones and slowly increase the volume, using the volume control on the
headphones to adjust the volume to the desired level.
Switch between the audio sources using the small channel select switch on the headphones. How
the transmitter is installed determines what sources are available.
After each use, be sure to switch off the headphones to extend battery life.
When the headphones detect no signal for more than one minute, the headphones will power off
and the LED indicator will go out. Reactivate the headphones by pressing the power button.
7. TECHNICAL REFERENCES AND SUPPORT
