Presenter - what is it? The presenter is a remote control for switching presentation slides.
What is a presenter for
It is a well-known fact that most people perceive information best visually. Therefore, the use of presentations is an easy and effective way to convey important information to a large audience. Presentations are also used at lectures, at various seminars, at meetings, in a word, wherever there are speakers and listeners.
In order for the presentation to be successful, and the audience's attention not to be scattered during the report, it is important to switch slides in time and quickly. Doing this with a mouse and a computer is not very convenient - you have to be distracted from the audience, concentrate on the switching process, try to remember what you said earlier.
In order to make presentations easy and convenient, scientists have developed a special remote control for presentations - a presenter. One of the most popular models today is the Logitech r400 presenter.
Device appearance
So, we have learned how the presenter works, what it is and what this device is for. Now let's talk about how it looks. In electronics stores, the presentation presenter is packaged in a transparent blister, through which you can see that it is equipped with a red laser pointer, its range is 15 meters, the device does not require installation of drivers when used with modern versions of Windows.
On the back of the box there is information about the capabilities of the device and the scope of delivery. The package includes: the presenter itself, a wireless receiver, 2 standard AAA batteries, a case with documentation in which it is written how the presenter works, what it is, what it is for, how to troubleshoot if any.
The manufacturer provides a 3-year warranty and full technical support. The case is made of soft mesh material. The device itself is similar to a TV remote control. It has an ergonomic shape. Before first use, remove the white protective strip at the place where the presenter batteries are installed. The wireless receiver does not look different from a regular USB flash drive.

Pros and cons of the device
First of all, we would like to inform you that Logitech's r400 presenter is comfortable to hold in your hand. Due to the fact that all the buttons on it are of different sizes and shapes, it is convenient to use even to the touch. When you turn on the device in the computer, the presenter is perceived by the operating system as a keyboard.
It is recommended to use Microsoft Office PowerPoint instead of OpenOffice Impress to open presentations because the screen off button does not work correctly in OpenOffice. The speed of switching slides depends on the power of your computer.
The presenter's laser pointer works well in rooms without lighting and at a distance of 5 meters. At a distance of 10 meters from the slides and in bright light, the laser indicates objects noticeably worse. The battery life of the device is quite long. When using a pointer, the batteries should last for 20 hours of continuous operation, without using a pointer - up to 1000 hours.
If the batteries are almost empty, the range of the laser pointer will be noticeably reduced.
Logitech's r400 Presenter is easy to use, comfortable and ergonomically designed.
