Installing a new antenna may be necessary if you are having trouble sending and receiving calls. Installation should only be done as a last resort, after trying all other possible solutions as listed in the Nokia 8290 Troubleshooting Guide. Installation requires no prior knowledge of mobile phone antennas.

Depress the button.
