Introduction

Thank you for purchasing this Direct Supply Direct Choice Digital

TENS Device from Direct Supply Equipment & Furnishings, a

division of Direct Supply, Inc. In this owner’s manual, you’ll find

important information that you should read before using this

product. Please keep this manual available for future reference.

Should you have any questions, please contact your Direct

Supply Equipment & Furnishings account manager.

Transcutaneous Electrical Nerve Stimulation (TENS) is a non-

invasive, drug free method of helping to control pain. TENS

uses tiny electrical impulses sent through the skin to nerves to

modify pain perception. TENS does not cure any physiological

problem; it only helps control the pain. TENS does not work

for everyone. However, in most residents it is effective in

helping to reduce or eliminate the pain, which may allow an

individual to return to normal activity.

Check your Direct Supply Direct Choice Digital TENS Device

each week based on the following checklist:

1. Check the device for external damage, such as deformation

of the housing and damaged or defective output sockets.

2. Check the device for defective operating elements, such as

the switches or knobs. Check the legibility of labels.

3. Check that the LCD is displaying information when a

channel is turned on.

4. Check the usability of accessories. Check that the cables

and electrodes are not damaged. If the device seems

to be damaged in any way, do not use the device and

contact Direct Supply Equipment & Furnishings for

troubleshooting assistance.

Device Description

The Direct Supply Direct Choice Digital TENS Device is a battery-

operated pulse generator that sends electrical impulse electrodes

to the body and reaches the nerves that are causing pain. The

device is provided with two controllable output channels, each

independent of the other. An electrode pair can be connected to

each output channel.

The electronics of the Digital TENS Device create electrical impulses

whose intensity, duration, number per second and modulation may

be altered with the controls or switches. Dial controls are very easy to

use, and the slide cover prevents accidental changes in the setting.

Specification Technical Description

Channels Dual, isolated between channels.

Pulse

Amplitude

Adjustable, 0-100 mA peak into 500 ohm load each

channel.

Pulse Rate Adjustable from 2 to 150 Hz.

Pulse Width Adjustable from 50 to 300 µs.

Modes B(Burst), N(Normal), M(Modulation), SD1(Strength

Duration), SD2

Normal

Mode

The pulse rate and pulse width are adjustable. It

generates continuous stimulation based on the

setting value.

Burst Mode Burst rate: Adjustable, 0.5-5 Hz

Pulse width: Adjustable, 50-300 µs

Frequency: Fixed at 100 Hz

Modulation

Mode

Modulation mode is a combination of pulse rate

and pulse width modulation. The pulse rate and

width are automatically varied in a cycle pattern.

The pulse width is decreased by 50% from its

original setting in 0.5 seconds, and then the pulse

rate is decreased by 50% from its original setting

in 0.5 seconds. Total cycle time is 1 second. In this

mode, pulse rate (2-150Hz) and pulse width (50-300

µs) are fully adjustable.

SD1 Mode The SD1 (Strength-Duration) mode consists of

automatic modulation intensity and pulse in a 40%

range. The intensity is always increasing while

the pulse width is decreasing and vice versa. The

intensity is decreased by 40% while the pulse

width is increased by 40% in 5 seconds. In the next

5 seconds, the intensity is increased by 40% while

the pulse width is increased by 40%. Total cycle

time is 10 seconds. Pulse rate (2-150Hz) and pulse

width (50-300 µs) are fully adjustable.
