EXHIBIT C User Manual WIRELESS MICROPHONE FEATURE & SPECIFICATION FEATURE High sensitivity cardioid capsule. Special noise absorption parts inside the barrels, which eliminate switch shock noise and handling noise. Frequency with PLL synthesized control. Easy-opening battery compartment for quick battery replacement. Low battery LED indicator. The Lavalier microphone is very light and easy for using clip on the belt. It can be used with headset mic w/3.5mm screw type plug easily. OAPRWN >
SPECIFICATION
* Carrier Frequency Range : UHF band 790~806MHz
* RF Power Output : 2mW (max.)
* Spurious Emission : More than 45dB below carrier frequency.
* Frequency Stability : Within +0.005% with PLL synthesized controlled
* AF Reponse : 40Hz to 15KHz (+/-3dB)
* Maximum Deviation : th KHz within limiting compressor.
* Signal to Noise Ratio : 60dB(A-Weighted).
* Microphone Capsule : Uni-directional dynamic microphone
* Operating voltage : DC1.5Vx2 (UM-3 type)
* Current consumption : About 65mA (max.)
* LED Indicator : Power On-Off and low battery OPERATION 1.Push to open the battery cover. 2.Insert 1.5Vx2 batteries into the battery holder according to polarity (+) and (-) indication marked on the battery housing. 3.Fit battery cover back. 4.After setting the chosen frequency same as the receiver, push the power switch to ON, the LED indicator will flash to indicate the carrier frequency is sending out. 5.Push the power button to "OFF" when mic is not used, and remove the battery in microphone if not used for along time. This will prevent from the damage that a defective "leaking" battery may cause. 6. Switch the power "ON, the LED indicator flashing means that power supply is normal. if the LED indicator on light means that the battery is in need of replacement. If no flashing, there is no battery or battery is not properly inserted. MR-SU9 WIRELESS MICROPHONE , NAME OF COMPONENT |

Please take time to read this manual before asking after sale service, and check following points. if it also has unusual things, please contact with purchasing store. We are sincerely to serve for you. 1.Before connecting and operating the unit, check the voitage setting conforms to the voltage available in your area, 2.1f the LED indicator on light means that power supply is in need of replacement. Please replace 1.5Vx2 batteries and be sure the polarity (+)(-) of battery is connected properly. 3. Signal dropouts and noise may be suddenly encountered by interruption from outside, too long distance between microphone and receiver or battery in low power. In such a case, adjust receiver antenna or change new battery. 4.Do not drop the microphone on a hard concrete floor, nor strike the microphone head front with a fist or fingers, nor blow a breath strongly into the microphone head front.
~ ,.Remove the battery in microphone if not used for a {ong time. This will prevent from the damage that a defective leaking batter, may Cause.
