Chapter 1: Introduction Explanation of Pain Pain is a warning system and the body’s method of telling us that something is wrong. Pain is important; without it abnormal conditions may go undetected, causing damage or injury to vital parts of our bodies. Even though pain is a necessary warning signal of trauma or malfunction in the body, nature may have gone too far in its design.
Chapter 2: Cautions Do not use this device for undiagnosed pain syndromes until consulting a physician. Patients with an implanted electronic device, such as a cardiac pacemaker, implanted defibrillator, or any other metallic or electronic device should not undergo TENS treatment without first consulting a doctor.

Chapter 3: Warnings TENS devices should be used only under the continued supervision of a physician. TENS devices have no curative value. TENS is a symptomatic treatment and as such suppresses the sensation of pain, which would otherwise serve as a protective mechanism. TENS is not effective for pain of central origin.
Chapter 5: Adverse Reactions Skin irritation and electrode burns are potential adverse reactions. If skin irritation occurs, discontinue use and consult your physician. Chapter 6: General Description The Fortress TENS is a battery operated pulse generator that sends electrical impulses ®...

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 decreased by 40%. Total cycle time is 10 seconds.Pulse rate (2~150Hz) and pulse width (50~300µs) are fully adjustable The SD2(Strength-Duration) mode consists of automatic modulation...

REF No. Description Quantity KB - 24 Electrodes Leads 2 pieces GC - 01 9 V Battery, type 6F22 1 piece Instruction Manual 1 piece Carrying Case 1 piece Label The label attached to the back of device contains important information about this device - model name, serial number (started with manufacturing year and week of the device), supply voltage, name of the manufacturer, CE number and classification.
Chapter 12: Operating Instructions Insert the 9V battery into the device’s battery compartment. Make sure to remove the plastic seal on the 9V battery. Line up the positive and negative terminals on the battery with their corresponding terminals in the device. Make sure that both Intensity control (ON/OFF Switch) knobs are in the off position.

The choice of which pulse duration to use is partially dependent upon the Treatment Mode and Protocol selected (refer to the appropriate section). Pulse Rate The Pulse Rate (hertz or pulses per second) chosen depends greatly upon the type of electrode placement given to the patient.
Time Duration The onset of pain relief should occur shortly after the intensity setting has been determined. However, in some cases, pain relief may take as long as 30 minutes to achieve. TENS units are typically operated for long periods of time, with a minimum of 20 – 30 minutes and in some post-operation protocols, as long as 36 hours.

Caution Do not insert the plug of the patient lead wire into any AC power supply socket. Chapter 15: Lead Wire Maintenance Clean the wires by wiping with a damp cloth. Coating them lightly with talcum powder will reduce tangling and prolong life. Chapter 16: Electrode Options The electrodes are disposable and should be routinely replaced when they start to lose their adhesive nature.
Contiguous Placement This is the most common placement technique. It involves placing the electrodes alongside the area of localized pain site, in such away as to direct the flow of current through or around the area of pain. In a single channel application, this would involve placing each pad on either side of the pain site if the pain is localized on a limb and deep within the tissue.
It may be helpful to rub skin lotion on electrode placement area when not wearing electrodes. Never apply electrodes over irritated or broken skin. Chapter 19: Application of Reusable Self Adhesive Electrodes Application Clean and dry the skin at the prescribed area thoroughly with soap and water prior to application of electrodes.
Care and Storage Between uses, store the electrodes in the resealable bag in cool dry place. It may be helpful to improve repeated application by spreading a few drops of cold water over the adhesive and turn the surface up to air dry. Over Saturation with water will reduce the adhesive properties.

Power On/Off Switch and Intensity Controls: If both controls are in the off-position, the device is switched off. By turning the controls clockwise, the appropriate channel is switched on and the indicator of power (CH1 or CH2) will reveal on the LCD. The current strength of the impulses transmitted to the electrodes increases further when the control is turned clockwise.
