To check whether it is turned on, press the key in the normal mode, " " key and hold for a few seconds, if the word appears on the screen the TEST, it's okay. Do not touch anything, to exit dial Dialing codes necessary at a time when the phone is in normal operating mode. If TEST word does not appear, it means that the test mode on your device is turned off. It can be enabled either by themselves, using Motorola test card SIM-emulator, or by contacting a specialist, having the necessary equipment and skills.

First, you need to learn how to type on the phone "break" hereinafter, it will be denoted by p. The display apparatus "pause" is displayed a small square. After entering the command, press "OK". Do not forget to enter the code pppp1p, pppp1p, pppp0p, which allow you to edit your phone's menu to enter codes described below.

Lifetime: Local storage does not expire.A wiring diagram is a simple visual representation of the physical connections and physical layout of an electrical system or circuit.

It shows how the electrical wires are interconnected and can also show where fixtures and components may be connected to the system. Use wiring diagrams to assist in building or manufacturing the circuit or electronic device. They are also useful for making repairs. For example, a home builder will want to confirm the physical location of electrical outlets and light fixtures using a wiring diagram to avoid costly mistakes and building code violations.

SmartDraw comes with pre-made wiring diagram templates. Customize hundreds of electrical symbols and quickly drop them into your wiring diagram. Special control handles around each symbol allow you to quickly resize or rotate them as necessary. To draw a wire, simply click on the Draw Lines option on the left hand side of the drawing area. If you right click on a line, you can change the line's color or thickness and add or remove arrowheads as necessary.

Drag a symbol onto the line and it will insert itself and snap into place. Once connected, it will remain connected even if you move the wire. If you need additional symbols, click the arrow next to the visible library to bring up a drop down menu and select More. You'll be able to search for additional symbols and open any relevant libraries. You can also change the size and shape of your line hops. Select Show Dimensions to show the length of your wires or size of your component.

Click here to read SmartDraw's complete tutorial on how to draw circuit diagrams and other electrical diagrams. A schematic shows the plan and function for an electrical circuit, but is not concerned with the physical layout of the wires. Wiring diagrams show how the wires are connected and where they should located in the actual device, as well as the physical connections between all the components. Unlike a pictorial diagram, a wiring diagram uses abstract or simplified shapes and lines to show components.

Pictorial diagrams are often photos with labels or highly-detailed drawings of the physical components.

If a line touching another line has a black dot, it means the lines are connected. When unconnected lines are shown crossing, you'll see a line hop. Most symbols used on a wiring diagram look like abstract versions of the real objects they represent. For example, a switch will be a break in the line with a line at an angle to the wire, much like a light switch you can flip on and off.

A resistor will be represented with a series of squiggles symbolizing the restriction of current flow. An antenna is a straight line with three small lines branching off at its end, much like a real antenna.

More Information. Electronic repair guide is engineered by Jestine Yong and contains safe approaches that can help you repair your electronics even if you don't have any technical skill or experience.

The guide, which comes in the form of three e-books, is written for technical college or university, hobbyists, and beginners as well as for anyone who is interested in electronics or those who have long experience in electronic repairs. With this guide, you won't need a certificate or diploma or any level of education in electronic engineering for you to start troubleshooting and repairing electronic equipment.


Once you read the three books from cover to cover and start practicing using the knowledge you have learned, you may even get better than any person with a degree. These three books are for anyone who has an interest in electronic repair but does not want to enroll in a college for whatever reason. They are authored in a language that is easy to understand even for those with zero knowledge of electronics. Read more Recently several visitors of blog have asked me about this book, which is being advertised quite widely across the Internet.

So I purchased a copy myself to find out what all the excitement was about. In addition to being effective and its great ease of use, this eBook makes worth every penny of its price. Refer to the schematic diagram in Fig 1.

Together, these devices contain an incredible amount of circuitry which permit building a highperformance DTMF decoder with a minimum of parts. A color burst TV crystal controls all of the digital timing functions therefore, no critical, interactive adjustments are required. A received audio signal is said to be present when the COS signal is greater than 0. The play record UV R pin of Ul. D flip-flop A is clocked on this positive edge, therefore making the Q output high.

The resistor R2 and capacitor C6 combination is used to generate a brief delay. The schematic diagram of Fig.Digital Phone. Brand of Radio. Radio Charger. Radio Antenna. Radio Battery.

The circuit represents a general-purpose astable multivibrator that alternatively energizes two heavy loads via a relay in this case, the loads are V incandescent lamps. This alternating blinker can thus be built at a lower cost, more easily and more compactly. Here P1 must be adjusted such that sufficient current is available to switch on transistor T1. This should occur when the voltage on the capacitor is around 1.

As a consequence, the relay pulls in. This causes R3 and P2 to be connected in parallel with R2 and P1. P2 must be adjusted such that there is not enough current left to provide the base current for T1.

This causes the voltage on C1 to drop, and a short time later the transistor is cut off. The relay then drops out, and the cycle starts over again. Operating power can be supplied by an unregulated V mains adapter for example.

The current consumption essentially depends on the two loads, since the alternating blinker circuit only draws the rated current of the relay. Each load is connected directly to the supply voltage, while the blinker circuit receives a stabilized supply voltage via the fixed voltage regulator IC1. Diode D1 protects the circuit against an incorrectly polarised input voltage. To set up the circuit, first turn P1 to minimum and P2 to maximum resistance.

Now turn up P1 slowly! Repeat the same process with P2 until the relay again drops out. The author used a BC for T1. If this is difficult to obtain, a BC Darlington can also be used. The proper operation of the circuit also depends on the type of relay used. In one prototype model, the relay pulled in OK and energized R3 and P2, but it refused to do anything further. If your construction exhibits similar behavior and you are dependent on a particular type of relayit may help to include capacitor C2 in the circuit as shown in dashed outline in order to slightly delay the effect of switching in P2 and R3.
