A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of Uniden LRD 737, along with an item. The lack of an instruction or false information given to customer shall constitute grounds to apply for a complaint because of nonconformity of goods with the contract. In accordance with the law, a customer can receive an instruction in non-paper form; lately graphic and electronic forms of the manuals, as well as instructional videos have been majorly used. A necessary precondition for this is the unmistakable, legible character of an instruction.

What is an instruction?

The term originates from the Latin word „instructio”, which means organizing. Therefore, in an instruction of Uniden LRD 737 one could find a process description. An instruction's purpose is to teach, to ease the start-up and an item's use or performance of certain activities.

Why don't we read the manuals?

Usually it results from the lack of time and certainty about functionalities of purchased items. Unfortunately, networking and start-up of Uniden LRD 737 alone are not enough. An instruction contains a number of clues concerning respective functionalities, safety rules, maintenance methods (what means should be used), eventual defects of Uniden LRD 737, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the Uniden service. Lately animated manuals and instructional videos are quite popular among customers.

    Speed Detection Systems A speed detection device (often called a radar gun) sends out either a microwave signal or beam of light. When this signal reaches its target, part of the signal is reflected or bounced back toward the emitting gun. The time required for the signal to leave the gun, bounce off an object, and return is used to determine a veh[...]

    Laser The Laser Speed Detection System, also called LIDAR (for Light D etection and Ranging), uses a laser gun that emits infrared light pulses just outside the spectrum of visible light. Each reflected pulse measures the speed of the object coming toward or going away from the laser gun. There are two Laser signals: Laser and Laser 2. Unlike radar[...]
