Text labels

The phones software has a built in service functionality that allows you to test some of the phones functions. (See point 2 above) It looks like this:

Main display

Camera

LED/illumination

Flash LED

Keyboard

1.2 Misuse and other no warranty issues

Misuse is not covered by warranty. This chapter will explain what’s not covered by warranty. Phones that have been exposed to misuse will not be covered by warranty.

This means: if it is possible to repair the phone, the customer will have to pay for the repair. SEMC will not allow any of these phones to be claimed into WCMS. Some local perspectives may interfere with this. Please reference to local directives.

1.2.1 Action

Make a general visual inspection for misuse.

Below are some examples of what is not covered by warranty.

1.2.2 Water indicator label

In the phone there is placed a sticker that can give you a hint to see if the phone is damage by liquid or not. This sticker is located near the type label (Fig. 1.2.1) and it is possible to see it without disassemble the phone.

Fig. 1.2.1

On the pictures below you will see the different between a sticker that has been in contact with liquid (Fig. 1.2.3) and with one that hasn’t (Fig. 1.2.2).

This sticker is ok

This sticker has not been in contact with liquid.

Fig. 1.2.2

This sticker is not

This sticker has been in contact with liquid. As you can see it has turn into a red or pink label. In this case you should check the phone for liquid damage (See point 1.2.2).

Note: There must be clear marks after liquid on the

PCB before rejecting the phone for repair.

12 Software Problem

• If there are problems with the response of the keypad commands, or spelling errors in the menu, if they are not related to mechanical damage, make a master reset and flash the phone with the latest software from EMMA II.

• Checking the software revision can be done in the Service info, see chapter Service functions in the software.

Choose: Service info / SW information. The Software revision and date will be shown in the display.

• If a flash upgrade is interrupted for some reason, EMMA II will prompt "Error in sequence". After which the phone will not start up. In order to restore functionality you need to run "S700x Flash Recovery". The script can be found under "Flash" in EMMA II. After a successful recovery you need to re-flash the phone with correct signalling software before start up.
