EXPAIN Change Neck & Shoulders
Correct placement is important to ensure correct measurements. EXPAIN Change Neck & Shoulders should be plased on top of the muscle between the neck and shoulder. Place on the side where it hurts the most, or on the right side if you are right handed or left side if you are a leftie.

The Change device measure muscle activity by measuring small electrical signals on the skin. The electrical signals are created by the nerves telling the muscle fibres to contract. When several muscle fibres are triggred the signal gets stronger. This signal is picked up by the adhesive patches in the Change Neck & Shoulders and the conductive surface areas of the Change Arm. The electronics and microprocessor within the unit amplifies, processes and digitizes the muscle activity. It detects muscle activity and detects muscle rest and muscle activity. When the muscle is active for a sustained time period, 30 seconds, the unit vibrates to alert the user and reminds you to take a break. The time of vibration and time it takes to reach resting level is stored and transmitted to the smartphone when connected.
The on/off button is inside the silver coloured ring. Press to turn on, press and hold until it vibrates to turn off (around 3 seconds). If nothing happen, the unit needs a recharge.
The unit vibrates hard to tell you that it is low on battery. Connect to a powered USB socket to charge. After an hour of charging, the unit is fully charged and ready to use.
The adhesive patch last all day for around 10 days. If the patches loose some of its adhesive capacity the patch can be rinsed in cold water to refresh the adhesive capacity. If the patches are worn out and rinsing in cold water does not help, the patch is ready fore replacement. New patches can be bought here.

Place the armband at the thickest part of the forearm with the oval part of the armband over the muscles that are activated when the finger and hand is elevated.
