Only in the beginning of the initial phase (Phase 1), the anode
(red cable) is slightly more effective than the cathode (black
cable).
Hint:
It is recommended NOT to reverse polarity within any given treat-
ment session.
Types of Current
The DP450 has several options for the type of current used during treatment:
-
DC: Direct Current (standard)
-
PC: Pulsed Current
PC is recommended as an option for treatment of underarms, or treatments
where the skin is more sensitive, or for the treatment of children.
Direct Current (DC):
In DC, the current (voltage) is being transmitted 100% of the time.
DC is the standard current of the device, and is the most efficient method of tap
water iontophoresis treatment available.
Due to user comfort preferences, this device gives the user the option to choose
PC as an alternative.
Pulsed Current (PC):
In PC, the current alternates its transmission between ON (the pulse) and OFF
(the pause) for equal lengths of time. The pulse and the pause are the same
duration
1
(equivalent to a pulse-width of 50).
PC can be practically imperceptible at certain voltages and allows a better com-
fort level, but is typically slightly less effective.
Hint:
Once selected for the treatment session, the pulse-width will remain the
same throughout the session. If the user desires to change the pulse-
width for better comfort or more efficiency, then the treatment must be
stopped. Power must be cycled on the device to return to Setup Mode
to change the pulse-width.

for example, 50 microseconds ON and then 50 microseconds OFF, and then the cycle repeats
