Disable or Remove Certificates
If a certificate is compromised, or your organization chooses not to
trust it, you can disable or remove it.
1 Start the Settings app and tap Security > Trusted credentials.
The trusted credentials screen has two tabs:
• System shows CA certificates that are installed in the ROM.
• User shows CA certificates you have installed yourself.
2 Tap the name of the certificate to disable or remove. The certificate
details screen appears.
3 Scroll to the bottom of the details screen and tap Disable (for
System certificates) or Remove (for User certificates).
4 Tap OK.
About Bluetooth Communications
The CN51 is Bluetooth-enabled, which lets you connect to other
Bluetooth devices.
You need to turn on the Bluetooth radio before you can discover and
connect to Bluetooth devices. By default, the radio is turned off.
The Bluetooth radio maintains its current state through a system
reset. If you perform a factory data reset, you must recreate pairings to
devices.
System bar icons indicate Bluetooth status.
Note: If necessary, you can enable a disabled System certificate from
this location. If you remove a User certificate, you must install it again
to enable it.
