1, Customer Inquire
2, We offer three kinds of appearance design proposal according to Customer's request for customer to choose. Include the rough size, color, button numbers, shell shape(clamshell , candy bar, slider,
3, After customer choose the design, then we will modify the chosen design to details.

then we start the hardware development, include plastic case mould, rubber keypad mold, PCB mold,

LCD display panel mold. it takes 40 days more or less.

4, we will start the software development at the same time, there are two methods.

 1),  customer supply to us the transmission protocol and specification.

 2),  customer supply to us a sample, then we copy the code and make the same. it takes 15 days.

 5, after finish all, we will test the sample, include the functional test, engineering test. like the drop testing, transmit distance testing, transmit angle test. high temperature test, low temperature testing and so on.
6, After customer confirm samples and before put into production.

we will supply to customer the list of the below documents.

1, Technical Specification,

2, Functional Block Diagram

3, Part list

4, Component specification.

5, Software specification, source code, hex code and flow charts.

6, PCB layout.

7, Circuit diagram

8, mechanical drawings (shell drawing, rubber keypad drawing, LCD display drawing.)

9, Engineering test reports.

10,Production file.
