1. INTRODUCTION
Thank you for purchasing UEM monitoring system. It has many advantages of in-ear
monitoring including: better sound quality, more mobility, personal adjustment,
etc. Better sound quality means high fidelity without risky feedback. More mobility
means the mix is mobile with the owner together. Personal djustment means it
forms a personal mix, and adjusts the personal levels.
The UEM Monitor System
The UEM monitor system is a frequency-sensitive system with in-ear monitor,
which is used in a wide range of applications. The product is suitable for school
speech, meeting speech, teachers and performer on stage.The features aid to
solve the problems from stage monitoring.
The UEM-8DR is new bodypack receiver which works as a wired receiver, a wireless
receiver, or both at the same time. The UEM-8T is another unique design for in-ear
monitoring.
Connect the two line-level or MIC level inputs directly into the transmitter and
then the two signals can be mixed together. Connect microphones or instruments
directly with the inputs or with UEM-8T, and use line outputs from a mixing console.
In a word, no matter what kind of output device you use, it can be plugged into
The whole UEM monitor series include the EB earphones and it has a dynamic
driver to produces crisp, full-spectrum sound. They have various sleeve options
for the best fit and isolation for ears. The EB earphone can operate wellwith CD
players, MP3 players, and anything else with a 1/5 inch (3-5mm) stereo output.

4.3.5 Battery Replacing & Installation
The double colour LED turns red, this indicates the battery low. Please replace
them with new batteries.
Please pay attention to that battery positive/negative should exactly correspond
to that of the receiver before the battery replacement. There is explosion
danger if the battery is incorrectly replaced. Replace the battery only with the
same or equivalent type.
.
Note:
1 After operation the unit should be switched off as well. Otherwise the batteries
will soon be exhausted. If LED of receiver lights up green, this indicates that the
receiver works well. If LED lights up red, this indicates that the wireless receiver
do not work. Please check if the channel is the right one which corresponds to
that of the transmitter. .
CAUTION
