Stimulation issues may include:

• Missing Impulse
• Flickering
• Sudden Appearance or Disappearance of Stimulation
• Stimulation Spikes

To identify the cause of the issue, it is crucial to narrow down and pinpoint the faulty part. Stimulation issues can arise from one or more of the following components:

• Stimulation Unit (Actiwear, Newave, Actiwave)
• Suit Cable
• Electrodes

Preparation Before Checking

1. Ensure that the Actiwears in question are fully charged.
2. Prepare and separate all the suits, making sure to differentiate them during the test.
3. Visually inspect all parts for damage.
   
4. Make sure that every part is fully connected to each other.

Checking Stimulation Manually

1. Place the suit open on a flat surface.
2. Connect the stimulation unit to the suit.
3. Start a training session with the following settings:
• Manual Settings
• Impulse Settings:
• Continuous Impulse
• 50 Hz Impulse Frequency
• The impulse intensity may vary depending on the person checking it.
4. If there is an electrode cover, slightly fold it away on both sides and check for an impulse. Make sure to check the channel on both sides. Refer to the picture below for guidance.
5. For DrySuits, touching both pads of the same channel can help check for stimulation issues.

Identifying the Issue

1. After checking a combination of suits, note the combination and record which channels produce stimulation problems.
2. Check the suit with a different stimulation unit.
• If the problem persists with a different stimulation unit, the stimulation unit can be ruled out.
• If the problem is resolved with a different stimulation unit, the original stimulation unit is faulty.
3. If the same stimulation unit is used on different suits and only one suit produces a problem, identify if the issue comes from the suit cable or the electrodes.
• Replace the electrodes with another set known to be working. If the issue is resolved, the original electrodes were faulty.
• If the problem persists after replacing the stimulation unit and electrodes, the suit cable is likely faulty.
  

Maintenance of Each Component

Stimulation Unit

Actiwear

• Ensure the Actiwear is fully charged. If there are problems switching it on, leave it on charge for around 6 hours.
• Confirm the charger is working. If in doubt, try charging with a different charging unit.
• Clean the end of the connecting cable, ensuring no contamination is present. Use a suitable cleaning substance for electric parts and a soft brush.

Actiwave/Newave

• Check if the DSUB port is free of contamination. Refer to the picture below for a working DSUB port with its spiral cable.

Suit Cable

• Clean the contact points of the suit cable using a cleaning substance suitable for electric parts and a soft brush. Clean the snaps in the same manner.
• For spiral cables with DSUB connections, ensure all pins are straight and undamaged. Refer to the picture below for an example of damaged pins.

Electrodes

• Clean electrodes with a suitable cleaning substance for electric parts. Refer to the picture below for a properly cleaned snap and electrode.
• Clean the electrodes thoroughly during maintenance. Refer to the picture below for an example of contaminated electrodes and snaps.
