This trainer is part of Labtech's communications training program. This trainer is designed to instruct service technicians in the operation, theory, programming, servicing, problem diagnosis and repair of cellular mobile systems. The trainer is based upon a popular brand CDMA and GSM Phone, which has been specially modified to facilitate training, allows easy access to the internal parts and components and includes a special electronic fault insertion system.

The trainer allows access to all the factory recommended key points for the taking of measurements for analysis and adjustment. The training program covers the study of digital cellular telephony including the basic functions of CDMA and GSM, telephone keyboard and display, microphone and loudspeaker, internal construction and function of components, Digital signal Processor (DSP). The trainer allows for connection to a PC for programming and operation.

The teaching program is designed to follow the service procedures as recommended by the manufacturer and uses the factory service manual in conjunction with student job sheets along with a text on fax servicing and theory. Each trainer comes with complete courseware as follows:

•  Service manual with detailed circuit board schematic diagram

•  Student job sheets with fault troubleshooting guide

•  Accompanying text book on cellular telephones covering operation, theory and repair

A unique fault insertion system is built into the trainer for student instruction purposes and includes 10 faults. The system features a Schematic Block Diagram silk-screened onto an integral fault board that utilized LEDs to indicate the nature and location of the fault. Touching an electronic switch activates the fault, single or multiple faults may be introduced at any time. Activated faults are visible as the corresponding LED illuminates on the fault board. The LEDs can also be switched off thereby not allowing the student to know where the fault is, this feature is ideal for testing the student's troubleshooting ability.
