VGWHEI-18YWireless Belt Worn Microphone

- 1 - Tour Mic Instructions Transmitter Receiver I. Precautions when using Caution: • To prevent the electromagnetic wave from influencing medical equipment, make sure to switch off the unit's power when placing it in close proximity to the medical equipment. • Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 1. Batteries Black Button slid from the Body Battery Case ( AAA x 2) - 2 - (1) How to open the battery case As pushing up the black button on the side, slide the battery case horizontally from the body. Snap the battery case open by the upside. (2) Dry cell batteries Size AAA alkaline batteries When mounting replacement batteries, be sure not to mistake the polarity. If the polarity is reversed, the battery will discharge all at once and may be incapable of being reused. (3) Battery life should be about 20 hours if used continuously. (4) This model has functions to extend battery life and device for not used continuously. (5) When the battery power gets low, the LED lamp flashes to let you know it's time to change the batteries. (6) If there is a strange noise on the receiver side or if the majority of the receivers are hard to hear, replace the batteries of the transmitter or check if the plug is loose or there is dust in the jack. 2. Transmitter/receiver operation Transmitter Receiver (1) Power on Lightly pressing the power button of the transmitter/receiver turns the power on and lights the red LED lamp. (At first, gradually increase the volume with the volume knob.) At this status, the transmitter/receiver is working normally. (2) Standby mode Transmitter: If there is no communication for approximately 20 seconds, the LED lamp goes off and the equipment switches to "standby mode." Receiver: Linked with the transmitter, and change into “standby mode” immediately. (Applying for a patent) The LED lamp goes off (but power is not cut off). When in "standby mode," when a call is initiated by the transmitter side, the LED lamps of both the - 3 - transmitter and receiver light and communication commences automatically. (It may take about 1 second for communication to commence.) If you press and hold the power of both the transmitter and receiver for several seconds, the LED lamp flashes and the power is shut off. (2) Active mode When the transmitter detects voice input, the receiver is switched to standby mode automatically and starts communication – the receiver is linked with the transmitter. The transmitter/receiver can be reset by pressing the on/off switch for no more than 1 second. (3) The device has 10 channels (0 - 9CH). Set both the receiver and transmitter to the same channel when using. If the lines are crossed, try another channel. (See the following precautions when selecting/switching channels with the channel selector.) (4) When plugging the microphone in the microphone jack of the transmitter and earphones in the earphone jack of the receiver, be sure to insert all the way. If not inserted all the way, you will not be able to transmit/receive properly. (5) Noise may be produced if the plug or jack is dirty. If so, wipe away dirt from the plug and jack with a soft cloth, etc. (if used in areas where there is a lot of sand or dust) (6) Stretch out the microphone cord and earphone cord when using. (7) The transmitter microphone cord and the receiver earphone cord break easily. Be careful when handling the cords. (8) Signals may get mixed with the frequency of local broadcasting stations in small areas. If so, transmission/reception may be temporarily interrupted. Using a cellular telephone in the immediate vicinity may produce noise. This does not however indicate equipment failure. Try a different location. 3. Standby mode (1) If there is no voice communication for approximately 20 seconds, the equipment is designed to switch to standby mode in order to extend the life of the batteries. When the transmitter switches to standby mode, the receiver being used also automatically switches to standby mode and stands by to receive a transmission from the channel that had be used up to that point. - 4 - (2) Standby mode is when the equipment becomes dormant without the power being cut off completely; the equipment uses minimal power while waiting for transmission/reception. (3) Functions in the standby mode are as follows: The receiver waits for a transmission from the transmitter. (The frequency of the current channel is used. If the channel is changed, the transmission cannot be received.) The LED lamps of both the transmitter and receiver go off (but power is not cut off). (4) When a radio wave of the frequency of the channel that had been used up to then is transmitted from the transmitter side, the receiver automatically begins receiving, all function restart and the LED lamp lights. (5) Important The microphone regards not only audio signals as signals; it regards all signals including noise and scratching sounds as signals. The equipment is therefore programmed so that the circuit does not re-open unless you talk for a relatively long period of time (about 1 second). You should note that the initial word is not transmitted. 4. Auto power off function This is a function for saving electricity, and is a measure for when you forgot to turn power off. Transmitter: If nothing is inputted for approximately an hour, the auto power off function is actuated, and the power of both the transmitter and receiver is cut off. Receiver: If transmitter does not send signal for approximately an hour, the auto power off function is actuated, and the power of both the transmitter and receiver is cut off. In this state, both the transmitter and the receiver do not go back to “active mode,” automatically. Turn the power back on by pressing the power switch (no more than 1 second). 5. Other precautions when using (1) No exposure to water The equipment is not water-proof. If it gets wet from drops of w…

RE: Seiden Electric Engineering Co., Ltd FCC ID: VGWHEI-18Y 1.) You have requested the Internal Photographs be held Confidential. In general, this Exhibit cannot be held Confidential without substantial justification. In my opinion, this requirement has not been met .Please provide a detailed rationale why Internal Photographs should be held Confidential. Answer: We accept that the pictures could be shown on the FCC website and therefore should not be considered as confidential information. 2.) Please do a final double-check on the model numbers. There seems to be instances where moth “...18Y” and “...18YT” are confused. Kindly do one last double check of your Exhibits. Answer: We have corrected the typos and the terminology of the product is 18YT. Please refer to the uploaded manual, operation description and label. 3.) Please note that the FCC logo is not appropriate for this device. Only computers and computer peripherals which follow the DoC equipment authorization procedures are to use this mark. Answer: The label has been corrected and uploaded. 4.) Please provide a tune-up procedure. This is required for all Licensed radio transmitters.
