Chapter 2.The AH-TU2 electrical stimulator
2.1 General
The AH-TU2 is a two channel nerve stimulator. This unit has ten pre-set programs (indicated
by P1 to P10) and ten user adjustable programs (indicated by U1 to U10), including six
modes. They are on/off, standby, preset mode, treatment time user preset mode, program
mode and user adjustable mode. There are two channels on the top of the device which work
independently of each other. Two different forms of stimulation may be used simultaneously.
You can also use just one channel. It is also possible to adapt user programs and pre-set
programs to mask them (render invisible to the user). These options are to simplify the use of
the device. The AH-TU2 will always start with the last used program and time. If no button is
pressed within 3 minutes while in the wait mode, the unit will turn off automatically.
2.2 Controls Explanation
All programs or settings are selectable and controllable by pressing these buttons. Programs,
intensities and other settings will be visible in the display.

2.3 Button Explanation
2.3.1 On and Off
Press the [ON] button to enter the standby mode.
Consult your medical practitioner before altering any programs to this unit.
Press the [M] and then [ON] button and hold both down until user programs appears in
display.
Press [Timer] and [ON] button to enter the preset programs. (See chapter 4)
Press the [OFF] button and device turns off.
For safety and prevention of accidental increases of output to this device the AH-TU2 locks
after several seconds of use. Pushing Ch1- & Ch2- simultaneously will “UNLOCK” the unit.
You can now turn the unit OFF or increase or decrease the intensity of the AH-TU2.
2.3.2 Mode
The mode [M] button scrolls through the programs one at a time. The button scrolls through
the programs in one direction only so if you pass the program you want you have to continue
to scroll until you return to the correct program. It is also used as the enter button when
changing setting in user program mode.
2.3.3 Timer
Pressing the “Timer” button increases the time span for treatment in increments of 5 minutes.
(Range from 0 to 90 minutes). Holding the timer button down will advance the time quickly,
up to 90 minutes. Pressing the timer button once more will place the unit in continuous mode.
The timer symbol will disappear when set as continuous work mode. (Time will show --.--)
2.3.4 CH1+/CH1- and CH2+/CH2-
Pressing these buttons while in standby mode allows you to adjust the intensity by 0.5mA
each step (range from 0.5mA to 70mA). The buttons on the right-hand side of the device
control the right-hand side channel and vice versa. These buttons can also be used to set other
parameters on the device. When in user modes (U1 to U10), pressing the [CH1+] or [CH1-]
buttons will increase or decrease the intensity of each channel. As a safety feature, when
adjusting in large steps by holding the [CH1+] or [CH1-] buttons the output will stop
increasing after 10 steps. To increase further release and press the [CH1+] button again.
2.4 Battery compartment
The battery compartment is on the rear of the unit, press and slide down to release. Take care
to insert batteries correctly to maintain correct polarity and avoid damaging the unit.

Chapter 3. Getting Started
The device has 2 working modes:
Preprogrammed, and User Adjustable Program.
The preset program P10 has been chosen as the default program by your physician or
medical practitioner to meet the needs of most patients. The user, with permission from their
doctor or medical practitioner, can choose from other settings in the User Mode.
3.1 Cleaning the skin
It is important to take proper care to your skin. Cleaning your skin properly will ensure the
best possible contact with the electrodes and will help prevent irritation to the skin. It is
recommended that you remove all body hair where the electrodes are to be placed. Failure to
remove hair may impair good contact with the skin. Hair removal will also facilitate easy
removal of the electrodes.
3.2 Placement of electrodes
Caution:
Follow the instructions of your doctor or medical specialist on where to place the electrodes.
Follow all of the instructions included with the electrodes for trouble free usage.
3.3 Setting up the stimulator
After the electrodes are placed properly, you can activate the device, and select the desired
therapy. The device starts up with the last used program. Select the program(s) recommended
by your health care professional. In 4.1 of this manual you will find a summary of the
standard programs. The setting of user program parameters can be found in the 4.2.2 and
4.2.3 sections of this manual.
Each time you press the [M] button the unit will advance to the next program. Check if the
timer is set properly. Normally the timer is set to 30 minutes per program, unless your doctor
or specialist has altered this. The time you set up for each program will be saved and used
automatically if you select that program again.
After you have selected the desired program, you can set up its intensity. See section 2.3.2 on
page 6 for instructions. If the electrodes are not attached to your skin, the intensity level will
only advance to 9.5mA and then reset itself to 0. You will also see a warning sign [ ] on the
display. If so, check to see if the cables and electrodes are connected properly.
If you are only using 1 channel, e.g. the left channel, you should use the CH1 +/- buttons.
For safety reason to stop accidental changes the unit will automatically lock into the program
after 15 seconds; however the intensity level can be adjusted again by pressing the CH1- and
CH2- buttons simultaneously to unlock the device first.
For details concerning treatment mode, please see section 4.2 in this manual.

3.4 Treatment period
You should strictly adhere to the instructions of your doctor or specialist. If you need a longer
treatment period, you should first discuss this with your doctor or specialist before changing
your program. The stimulator you are using has been programmed to a 30 minute default
treatment and will turn off automatically after treatment.
3.5 Stopping your daily treatment
If you have activated the timer, the AH-TU2 will switch off automatically after your
treatment is complete. You can also end the program manually by pressing the [M] button or
turning down the stimulation until it reaches 0. When the current reaches 0 the device will
stop and enter standby mode. The device can also be switched off by pressing the [OFF]
button.
3.6 Removing the electrodes
Caution
Always switch off the device before removing the electrodes.
When removing the electrodes, follow the instructions on the electrode packaging.
3.7 Taking care of your skin
After you have removed the electrodes, carefully clean your skin with a mild soap. After the
skin is cleaned, a red mark from the patches and/or electrodes may be visible on the skin.
This is a normal reaction and usually disappears quickly (may take 30 –60 minutes on some
people).
3.7.1 Irritation of the skin
Despite all the precautions, it is still possible that you may experience skin irritations. Many
skin creams take good care of your skin, but are, unfortunately, not compatible with electrical
stimulation therapy. Most skin creams are oily or greasy and impair the flow of the current
onto your skin. We advise you to use a special TENS/NMES cream, which does not contain
any oils or perfumes. This cream is especially designed for this kind of stimulation and does
not impair it in any way. If you experience persistent irritation of your skin when using the
nerve stimulator, please contact your healthcare professional.
