TO REDUCE THE RISK OF ELECTRIC
SHOCK, DO NOT EXPOSE THIS
EQUIPMENT TO RAIN OR MOISTURE
This label appears on the rear of the unit due to
space limitations
The lightning flash with an arrowhead
symbol, with an equilateral triangle, is intended to
alert the user to the presence of annulated
‘dangerous voltage’ within the products enclosure
that may be of sufficient magnitude to constitute a
risk of electric shock to persons.
The exclamation mark within an equilateral
triangle is intended to alert the user to the presence
of important operating and maintenance (servicing)
instructions in the literature accompanying the
appliance.
Warning: To prevent fire or shock hazard, do not
expose units to rain or moisture.
Attention: Installation should be performed
by qualified service personnel only in accordance
with the National Electrical or applicable local
codes.
Power Disconnect: Units with or without
ON – OFF switch have power supplied to the unit
whenever the power cord is inserted into the power
source; however, the unit is operational only when
the ON – OFF switch is in the ON position. The
power cord is the main power disconnect for all
units.

Designed for wireless audio and video digital conferencing systems specifically, the system without complicated
cable installation, it can configured to: Conference discussion systems, multimedia video conferencing systems,
remote video conference system, the system using 2.4G band public, without any applications ,the advanced
frequency hopping 2.4G DSSS and digital transmission technology which greatly reduces the impact of various
interference signals, 2.4G has a unique transmission characteristics, whole have a bad ability of passes obstacles,
so it can prevented the leakage of signals, digital transmission technology, consummate communication
protocol to ensure security of the conference content, system that can meet the needs of ordinary fixed conference
room, and can also set up a mobile conference room, and in the convenient premise, providing a highly reliable
conferencing solutions.
n Features:
1. The system uses worldwide public 2.4G ISM band (2400-2483MHz), no need complex cable installation, no
need troublesomely frequency application.
2. Digital encryption self-adaption frequency hopping spread spectrum technology, high confidentiality.
3. Configurable 1-999 microphone units as needed. Under FIFO mode all microphone unit can click the TALK
button to start to speak. The default number of speaking simultaneously is limited to the last 4 people. The
number of speakers can be set to 1-4 in the host.
4. "FIFO", "LIMITED", "LIMITED TIME", "CHAIRMAN" 4 kinds of discussion mode, you can easily realize
conference management.
5. Any chairman unit can initiate a vote.
6. 4 input 1 output video signal control and automatic tracking of the current speaker.
7. 24-bit PCM high precision audio signal quantification processing, lossless wireless transmission, the sound
quality comparable to wired.
8. Built-in frequency shift, feedback suppression, intelligent balancing, etc anti-howling functions, effectively
enhance the sound transmission gain.
9. 1 system with 1 host, 1-999 microphone units. Microphone units including delegate unit and chairman unit,
delegate unit can be set as VIP, both units can be used in any combination statement.

n Safety Criterion
CAUTION: To prevent electrical shock hazard, do not expose the system equipment be exposed to rain or
moisture
1. Please read and note to the stripe with a warning symbol, these provisions will provide important safety
information.
2. The SH2191have been grounded by the power line.
3. To prevent the risk of electrical shock or leakage, do not open the SH2191chassis;
4. Make sure that any substance or liquid into the system equipment, to prevent short circuits.
5. Do not secretly conduct instructions without mentioned on the dimension
if any of the following circumstances occur, please contact repair center.
A. Any system device can not work properly (or some of part normal work).
B. the power line of SH2191be broken
C. substance or liquid into the system equipment
D. mechanical parts subject to severe impact.
6. Please pull out plug if the machine is free long time
7. Smoke situation, immediately shut down the system and disconnect the SH2191power supply.
8. System equipment with digital circuits, although these devices are complete anti-interference in the radio
interference measures, but when close to the radio, television or High power radio transmitters, and may still
electromagnetic interference. If there are any problems, Please stay away from the system interferes.
n Installation / warnings
In order to properly install the system and avoid electrical hazards, this chapter must have professional and
technical qualified engineering staff responsible for this content, it is not important to the user; the user does not
