2. Heed and follow all warnings.
3. Do not use this apparatus near water.
4. Clean only with a dry cloth.
5. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
6. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
7. Do not defeat the safety purpose of the polarized or grounding type plug. A polarized plug has two blades
with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The
wide blade or the third prong is provided for your safety. If the provided plug does not fit into your outlet,
consult an electrician for replacement of the obsolete outlet.
8. Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles,
and the point where they exit from the apparatus.
9. Only use attachments/accessories specified by the manufacturer.
10. Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the
apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury
from tip-over.
11. Unplug this apparatus during lightning storms or when unused for long periods of time.
12. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been
damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate
normally, or has been dropped.
13. Use the mains plug to disconnect the apparatus from the mains.
14. WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPARATUS
TO RAIN OR MOISTURE.
15. DO NOT EXPOSE THIS EQUIPMENT TO DRIPPING OR SPLASHING AND ENSURE THAT NO OBJECTS
FILLED WITH LIQUIDS, SUCH AS VASES, ARE PLACED ON THE EQUIPMENT.
16. THE MAINS PLUG OF THE POWER SUPPLY CORD SHALL REMAIN READILY OPERABLE.
SAFETY
To prevent electric shock do not remove top or button covers. No user service-
able parts inside. Refer servicing to qualified service personnel.
To completely disconnect this equipment from the AC mains, disconnect the
power supply cord plug from the AC receptacle. The mains plug of the power
supply cord shall remain readily operable.
To reduce the risk of electric shock, grounding of the centre pin of the plug
must be maintained.

INTRODUCTION TO CMS380
Thank you for purchasing AKG CMS380!
AKG CMS380 is a UHF Wireless Microphone System designed for applications where
wireless transmission is in demand. CMS380 is available in two sets:
Vocal Set Mix Set
1 x SR380 Dual-channel Receiver
2 x HT380 Hand-held Transmitter
1 x SR380 Dual-channel Receiver
1 x HT380 Hand-held Transmitter
1 x PT380 Pocket Transmitter
1 x HC380 Headset Microphone
Both the Vocal set and the Mix set include a SR380 UHF dual-channel receiver, featur-
ing interference-free and reliable transmission. SR380 offers 200 frequency band op-
tions and is capable for multi-system communications. Its Hopping Technology ensures
non-stop signal transmission during speech or performance.
The HT380 hand-held transmitter/microphone provides high and low transmission pow-
er options for applications in either small or large venues. The hand-held microphone is
unique for its auto mute function, which will put the microphone into sleep when left idle
for 15 seconds and resume active immediately when picked up.
The combination of PT380 pocket transmitter and HC380 headset microphone is meant
to free your hands. The PT380 pocket transmitter requires only a single 1.5V AA battery
to drive and has its gain individually set. The HC380 headset microphone aims not to
intrude your presentation or performance, hence, is designed in an ultra compact size
and beige colour. Besides, the headset is resistant to sweat and moisture and comfort-
able to wear for longer hours.
To make your voice or speech clear, accurate and interference-free, this is what
CMS380 Wireless Microphone System is designed for.
Features
• UHF frequency band, interference-free and reliable transmission;
• 200 frequency band options for multi-system communications;
• Advanced Hopping Technology for non-stop signal transmission;
• Infrared technology for easy & quick setup;
• Anti-collision protection;
• Auto mute puts the handheld microphone into sleep when left idle for 15 seconds;
• Precision engineered circuit for optimal acoustic performance and lower power
consumption.
