If a certificate authority (CA) certificate gets compromised or 
for some other reason you do not trust it, you can disable or 
remove it. 

1.   From the Settings screen, touch Security. 

2.   Touch Storage type to set a storage type for credential 

contents. 

3.   Touch Trusted credentials.  

The trusted credentials screen has two tabs:  

• System: Displays CA certificates that are permanently 

installed in the ROM of your device. 

• User: Displays any CA certificates that you installed, for 

example, in the process of installing a client certificate. 

4.   Touch a CA certificate to examine its details.  

A scrolling screen displays the details.  

Scroll to the bottom of the details screen and touch 
Turn off to disable a System certificate. 

Caution! When you disable a system CA certificate, the 

Turn off button changes to Turn on, so you can 
enable the certificate again, if necessary. 

Touch OK to return to the certificate list. 

5.   Touch Install from device storage, then choose a 

certificate and follow the prompts to install encrypted 
certificates stored on the USB storage. 

Note: You must have installed a memory card containing 

encrypted certificates to use this feature. 

6.  Touch Clear credentials to erase the credential 

contents from the device and reset the password. 

Note: This setting only appears if you have installed encrypted 

certificates.
