TECHNICAL SPECIFICATIONS
GENERAL:
Dimensions:
9.5" (24cm) W x 6.5" (16.5cm) D x 3" (7.6cm) H
Weight (including batteries):
3lbs. 14oz. (1.75 kgs)
Operating Power:
120/240VAC; 50/60Hz; 50W
4 x 1.5VDC “D” cell alkaline or rechargeable batteries.
Battery Life:
New alkaline batteries operate the system for 40 hours at full output and over 100 hours at normal
settings. Battery voltage is displayed and monitored. With the 4.4AH NiCad rechargeable cells the
system will operate approximately 10 hours at normal settings.
Display System:
Super Twist LCD full character display with adjustable contrast /viewing angle.
Push Buttons:
Conductive rubber with excellent tactile feel. Speed and sensitivity are fully adjustable.
System Memory:
The system remembers all prior custom settings from treatment to treatment in active battery powered
RAM memory. (Must be reset if the batteries are changed or discharged.)
System Architecture:
CMOS integrated micro-controller with on board memory and instruction set.
STIMULATION SYSTEM:
Output:
Constant voltage up to maximum preset current limit
Output Waveform:
AC sine wave into physiologic load, IFC and MFAC modes, and biphasic square wave (LVPC) or
monophasic pulsed current (HVPC mode). Output Amplitude: IFC FD and NMES modes-0 to 70 mA
RMS current into a 500

loads.
Channel Isolation:
Independent transformer isolation.
Line Leakage:
<50 µA when operated with the charger system.
IFC MODES:
Frequency Difference Rate:
Output channel A, fixed at 2KHz, 2.5KHz, 4KHz or 5KHz. Output channel B variable from channel A
fre 0.0 to 250Hz. Beat rate may be set during treatment.
Full Field Burst Rate:
0.1 - 999Hz
Rate Scan:
0 - 20 seconds, 0 - 50% modulation, upper and lower frequencies are fully programmable and sweep time
is adjustable in set mode.
Vector:

which varies concurrently out of phase.
MFAC MODE:
Waveform:
Modified sine wave into physiologic load 2KHz, 2.5KHz, 4KHz or 5KHz carrier frequency.
Burst Rate:
Adjustable from 0.1 to 999bps, 50% duty factor
Rate Scan:
From 0-50% programmable with scan time, programmable from 0-20 seconds
