 VK-1000 Digital Wireless Microphone with the function laser pointer and page turner

  System Host Introduction:

      Our company is designed omni-directional digital wireless microphone, which has the functions of electronic laser pointer, wireless presenter (page-turner), digital wireless microphone. This product adopts global opening 2.4GHz band, encrypted transmission, pen-shaped design, automatic identified frequency (up to 80 frequency points), built-in rechargeable lithium battery, beautiful shape, convenient to bring. It is especially for lectures, training, teaching, conferences and so on. It has a number of innovative technologies that can infinitely expand your wireless digital life!

1、A multi-function machine：

(1). Electronic laser pointer:

Integrated electronic laser pointer function, teachers can press a button of laser pointer anywhere of the classroom; they can focus on the lectures to be marked.

(2). Wireless Digital Microphone:

Using the opening global 2.4GHz band, encrypted transmission; MIC built-in, the pickup range of microphone is up to 30-50 cm.

(3). Wireless page-turner:

Integrated two-way USB interface of wireless page-turner; only if you gently press on the transmitter "page up," "page down" button, you can control PPT file remotely; you is no longer restricted to around the computers

 2、Automatic identified frequency or Manual identified frequency:

(1)Automatic identified frequency:

 To any classroom, you open the transmitter, within a meter from transmitter to receiver, transmitter frequency will be automatically matched with receiver frequency, it can work normally; the transmitter comes true one to many, one "transmitter” can be used in all the classrooms. Hundreds of devices can be used simultaneously in the school, without frequency interference problem:

(2) Manual identified frequency:

Turn on the transmitter and hold down the "        Page down" button 3-6 seconds until the work light appear to glitter; increase the number of channels through "Page down" button,  reduce  the number of channels through “Page up" button, adjust the transmitter’s frequency to be the same with receiver ‘s frequency through two buttons, it can work properly.

If you can not complete the identified frequency within 1 minute on the frequency after turning on the transmitter, you only turn off the transmitter, and then turn on it to identify the frequency.

3、No “frequency interference” and No "co-channel interference"

Using the opening global 2.4GHz band, encrypted transmission; Receiver can be divided into 80 frequency points and adopt the technology of  Automatic identified frequency, completely solved the "drop band", "co-channel interference" problem from the U, V analog microphone

4、Charge mode diversification.

The machine is built-in rechargeable lithium battery, charging time is 3-4 hours, continual work more than 8 hours. There are three indicator states: charging indicator light (red), charge full indicator light (green), low battery indicator light (yellow), three colors are on behalf of three kinds of working condition; ultra-low emission power, a veritable "green wireless microphone

The product has three ways to charge:

(1) Base Charging method:

Equipped with a charging base, both as a charging seat used in the charge, and also as a microphone stand to use; when it is being  charged , the product can work properly.
