Warranty Information
Advanced Mode allows the user to control the
type of the waveform generated by Acticare
IC by programming a series of parameters
that describe the wave shape and frequency.
This mode is very flexible, it allows the device
to be configured to provide a wide range of
stimulation modalities such as Neuromuscular
Stimulation and Electro-Acupuncture, at
frequencies from 1Hz to 500,000Hz.
There are three basic forms of wave
generated by Acticare:
8
Pulse amplitude.
The maximum voltage produced by Acticare
IC is 250V, but this is reduced as the
programmed pulse width increases to prevent
excessive levels of stimulation at longer pulse
widths. The peak voltage at 100% output
into 500ohms is indicated in the table.

2. Monophasic a square
waveform with single positive

prevent dangerous shock. The maximum
average current is also limited to 20mA in TSE
and TENS modes (40mA in IC mode). These
limits are not changeable by the user.
To Setup an Advanced Waveform
1. With the therapy mode switch in the
TSE/TENS position.
pressing the + and TIMER
when prompted to "PRESS + TO BEGIN
TREATMENT". The display will flash MODE
MENU as confirmation.
2. Select advanced mode "ADV"
and – keys.
3. Press TIMER to scroll through the
waveform parameters. Use the + and
to set values for each of the parameters
(available parameters are shown in the table
opposite).
4. Exit the Therapy Mode
selection by pressing and holding the TIMER
button.
If the message "INVALID" is displayed when
you exit, this means the waveform specified is
not possible for Acticare IC to produce. This
may occur for one of three reasons:
i. The sum of the pulse width (PULS) and
inter-pulse space (SPAC) you have specified is
longer than the time available at your desired
frequency (FRQ). You should reduce the pulse
width (PULS) or decrease the frequency (FRQ).
ii. The burst time (BT) you have specified is
too long for the burst frequency (BF). You
should reduce the burst time or decrease the
burst frequency.
iii. You are attempting to use waveform
frequencies below 50Hz in Burst mode, this is
not possible with Acticare IC.
