RF Troubleshooting

This document is written for use in conjunction with the WinTesla Tuning

and Testing software. Pictures of the menu structures are shown through

out the document. This document should be used in conjunction with the

phone's schematics which are referred to in detail throughout.

WinTesla has 3 key menus:

Configure Basic set up covered in WinTesla General Set Up

Testing

Tuning

Tuning is described in four parts:

Connect the phone to the PC COM port and start WinTesla. Select "Prod-

uct" and "New" and the phone configuration will be selected automatically.

Select "Configure" and "Frequency Plan". You will then be able to see and

also change the default AMPS and CDMA Channels. The cable loss

should also be entered here.

Note: It is possible to enter a Tx and Rx cable loss separately, however if

a single cable is being used then both losses should be the same. Also

the loss will be different for the 1900MHz band and the 800MHz band

hence sections for both.
