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.

1.2.2 Liquid damage sticker
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 SIM reader (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 ok
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.

5 Charging/Capacity Problems
• Make a general visual inspection for misuse, corrosion or oxidation from liquid damage
according to point 1.2
5.1 Charging
• Insert a working battery and connect a working charger to the phone. If the battery voltage
