The CES Ultra has two electrical configurations with two different frequencies: 100 Hz and 0.35 Hz. They are set using a dipswitch in the battery compartment. The frequency of choice is the 100 Hz which has the largest body of evidence as to efficacy behind it. It provides a gentle and calming tingling sensation, though it may also be used below the sensate threshold. The 0.35 Hz setting operates at a lesser amplitude, generating very little actual sensation, but with a more subtle impact. The user may pre-set the time for either configuration for 30 minutes or 45 minutes, at which point the current will automatically turn off, or to have the unit run continuously.
