6. Pulse Rate Control:
This dial determines how many electrical impulses are applied through the skin
each second. By turning these controls, the number of current impulses per
seconds (Hz) for both channels can be continually adjusted. Unless otherwise
instructed, turn the pulse rate control to the 70-120 Hz range.
7. Pulse Width Control:
This dial adjusts the length of time each electrical signal is applied through the
skin, which controls the strength and sensation of the stimulation. If no instruc-
tions regarding the pulse width are given in therapy set the control to the sug-
gested 70-120 uS setting.
8. Timer Control
Treatment time of TENS can be preset with timer control.
This switch has 3 positions, 15, 30 and 60 minutes.
Push the timer control until engaged in position desired.
3. On/Off Switch and Intensity Control :
If both controls are in the off-position (white markings on the housing), the
device is switched off.
By turning the controls clockwise, the appropriate channel is switched on
and the impulse display led will illuminate and begin to pulse according to
the fre quency set.
The current strength of the impulses transmitted to the electrodes increases
further when the control is turned clockwise.
To reduce the current strength or switch the device off, turn the controls counter
clockwise to the required setting or off- position.
4. Lead Connector
Connection of the electrodes is made with two-lead connector. The device must
be switched off before connecting the cables. Both intensity controls must be at
the Off position. Electrodes must be pressed firmly on the skin.
5. Mode Control
Expose the controls by sliding front cover down from top of unit. This switch has
3 positions: B for Burst stimulation, N for Constant stimulation, and M for
modulation stimulation. Push the Mode Selector until engaged in position
desired.
