## -1 Screen Unlock Error
**Error Message**
The parameter check failed or permission denied or system error.
**Description**
This error code is reported when a parameter check failure, permission verification failure, or system operation error occurs.
**Possible Cause**
1. The input parameter is invalid.
2. The required permission is not configured. For example, **ohos.permission.SET_TIME** is not configured for setting the time or **ohos.permission.SET_TIME_ZONE** is not configured for setting the time zone.
3. The system is not running properly due to a common kernel error, such as a memory allocation and multi-thread processing error.
**Solution**
1. Make sure input parameters are passed in as required.
2. Configure the **ohos.permission.SET_TIME** permission for setting the time and the **ohos.permission.SET_TIME_ZONE** permission for setting the time zone.
3. Make sure the memory is sufficient.
