The Symbol PDT 8100 does not attempt to change its default existing WEP keys during installation. If not changed, the PDT 8100 will reveal the WEP keys to any user in plain text by taping on the wireless icon on lower right hand of 8100 and scrolling to the ‘encryption tab’. A stolen PDT 8100 or copied keys can allow an insider the ability to totally compromise the Wi-Fi network.
