Ericsson T18s Trouble-Shooting Instruction page 9

2.3 Connect a call at powerlevel 5 towards the
instrument with an input signal of –
68.5dBm.
If you're not able to connect a call, open the phone and check for liquid damages.
Make sure the back cover isn't broken and that it is of the correct model as there are
two to choose from (fig. 2.1).
Replace the antenna connector (if it hasn't been replaced before) and try again. Note
that there are several models to choose from and it's important to mount the correct
one (fig.2.2).
If the phone still doesn't work then the fault is most likely Tx-related or there's a
feed voltage fault.
