User's Manual PLL UHF CREATIVE PEN-SHAPE MICROPHONE SYSTEM FCC STATEMENT 1. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. 2. Changes or modifications not expressly approved by the party responsible for compliance could void the user`s authority to operate the eauipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in aresidential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver isconnected. Consult the dealer or an experienced radio/TV technician for help. warning statement: RF The device has been evaluated to meet general exposure requirement. The device can be used in portable exposure condition without restriction. RF Turn on the unit and press and hold "SET" button for 3 seconds, it will enter pair mode with the channel number displayed flashing. Simultaneously the "READY" indicator below will flash green. But once it pairs with transmitter successfully, "READY" indicator will stop flashing and light solid green, Turn on the unit and short press "SET" Button to select the channel you like, the unit has total 16 channels which are represented by numbers "0-9" and the letters "A-F" separately, The channel numbers displayed will increase each time when you short press the button. 1 2 3 4 Power/Mute button: Press and hold for 3 seconds to turn the unit on or off, the indicator will light red firstly and change to light green after about 5 seconds. It enter normal operation mode. Status indicator: A quick press and release will mute or un- mute the transmitter when the transmitter is on. It will light red for mute and green for un-mute. IR LENS: This window is used to capture the infrared signal sent from receiver KRL/KRA, During the IR SET to channelize the transmitter, the IR Lens must face towards the receiver to load the selected channel. 1 2 "SET" Button Operation a. b. c. 3 4 5 6 KRL SPECIFICATIONS:KRL SPECIFICATIONS: KRL/KRA Mulit-Channel , up to 16 frequency presets for each frequency bands UHF470~494,542~566,823~832, 863~865MHZ Dependent on applicable country regulations PLL UHF SYNTHESIZED 100 Hz-12KHz ( 3dB) 0.005% (-10 ~ 50 ) C 1KHz <0.8% FM (F3E) >90dB >95dB -100dBm/12dB SINAD +6dBu MODEL Channel Mulit-Channel , up to 16 frequency presets for each frequency bands Frequency band Frequency response Oscillation mode Frequency stability T.H.D.
