VU8ZZWWIRELESS PTT

Wireless PTT Set User Manual Transmitters 1) You should pair two Transmitters with a Receiver PCBA before using wireless PTT, How to paring? See following pairing operation instruction. 2) Keep the Receiving PCBA at least 3cm away form the antenna when using. Otherwise the working range could be shortened. A working range of 1.5m between the transmitters and receiving PCBA is guaranteed if the instruction is follows. 3) Should connect the headset with Receiving PCBA，and then the radio on/ off LED should be turned on when two Transmitters have Paired with a Receiver PCBA and the PTT on the transmitters is pressed. Pairing 1) The WLPTT receiver PCBA provides a learning button for pairing The Transmitter and Receiver. Pressing the learning button enters pairing mode. 2) The receiver’s output will be assigned to the last two transmitters which are paired on. How to paring 1) Turn on the power; 2) Press the learning button on the receiver PCBA; you should hear a very distinct clinking sound which means the learning button is pressed; 3) Press the transmitter while keeping the learning button on the receiver PCBA pressed; 4) Release both learning button and transmitter; 5) Now the Transmitter and Receiver are paired on. 6) The Receiver can only keep two ID of The Transmitter, which is just a circle on the pairing of the receiver and transmitter; and the third one will overlay the first one. 7) After two transmitters are paired to one receiver; pairing one of them to the receiver once more, the other one will be kicked out. FCC WARNING 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. NOTE: The manufacturer is not responsible for and radio or TV interference caused by unauthorized modifications to this equipment. Such modifications could void the user’s authority to operate the equipment.

Circuit Description: This product uses the 915MHz public frequency and the FSK modulation system which is in favor of anti-electromagnetic interference, also its transmitting module and receiving modules has good anti-electromagnetic interference ability, moreover, the spike surface acoustic ware filter used by the receiving part plays an important role in raising the wireless PTT’s anti-interference ability. This product can be divided into two separate parts: the Transmitting Part & the Receiving Part. The Transmitting Part : Press PTT when the user needs to deliver words, then the SCM(Single Chip Micyoco) would start to work and carry out the procedure in the chip, and then output the signal to the RF module. Meanwhile, the 10MHz Crystal Oscillator begin to vibrate to drive the RF chip to work. The RF chip would match the network through an antenna after working, and transmit the particular signal of the 915 M Hz. Antenna, Ground, and Power Source The antenna using built-in forms, which consists of a φ1.0×6.8cm wire around in the PTT. There is no external ground connection. The ground is only that of the printed circuit board. Electric current of the transmitting part is supplied by a 3.0 Volt Lithium batteries.
