IFC / Premod Selections:
12. IFC/PREMOD: Press this key once to begin setup of an interferential treatment (the IFC
LED is lighted); press this key twice to begin setup of a premodulated treatment (the
Premod LED is lighted). When you select IFC, both channels 1 and 2 are automatically
selected and the green LED lights for those two channels will be on. Connect two leads
to the output jacks for the channels that are selected. When you select PREMOD, a
single channel (CH1 or 2) is automatically selected and that channel’s green LED will be
on. Connect one lead to the output jack that corresponds to the channel indicated by the
green LED.
13. HIGH/LOW TOGGLE (used with interferential, premodulated and high volt): Press this
key one or more times to select the desired frequency range for interferential and
premodulated treatments or the pulse rate range for high volt treatments. The green LED
indicates the option selected. For example, press the High/Low toggle key once to select
High, press again to select Low, press again to select High/Low Alternating, and press
again to select High/Low Consecutive. For high volt treatments, you can select High or
Low only, but not both. During a treatment, the current sweeps through the range(s)
selected.
For interferential and premodulated, the HIGH frequency range is initially set at 80 to
150 Hz; and the LOW frequency range is 0 to 10 Hz. For high volt, the HIGH pulse rate
range is initially set at 80 to 120 Hz; and the LOW pulse rate range is 1 to 10 Hz. These
frequency ranges may be modified for every treatment, if desired and new default settings
for the device may also be saved. See treatment setup instructions later in this manual for
a complete description of the options that may be selected.
14. TARGET/SWEEP TOGGLE: This key is pressed to select either Target, Target Sweep,
or static treatment for an interferential treatment. The Target pad is used to locate the
exact treatment site (if the Target option is selected during an interferential treatment).
15. TARGET PAD: For use during interferential treatments when “Target” is selected.
Touch the TARGET pad at different points on the pad to reach the precise treatment site.
When you lift your finger from the Target pad, the selected point is locked until you
change it again. This patented feature is used to locate the specific treatment site in an
interferential treatment and to place the point of interference at that point.
Ultrasound Selections (DYNATRON 850plus ONLY—the ultrasound feature is
not available on the Dynatron 550plus):
16. SOUND/COMBO: Press this key once to begin setup of an ultrasound treatment (the
Sound LED on this key is lighted as well as the Sound LED in the channel indicator
area); press this key twice to begin setup of a combination treatment (the Combo LED is
lighted as well as the Sound LED and a single Channel LED in the channel indicator
area). When either of these options is chosen, the soundhead should first be plugged into
the ultrasound output jack on the side panel. For combination treatments, the special
combo lead wire should be attached to the output jack selected (see full instructions for
setting up a combination treatment later in this manual). In the COMBO mode, the
electrotherapy treatment is delivered through the soundhead and through a single
electrode which is placed on the patient. Only single-channel electrotherapy options are
available in the COMBO mode.
