Remove any packaging and place pack in a clean and debris free domestic microwave oven. For microwave use do not exceed 30 seconds when heating from room temperature or 1 minute when heating from frozen. These times are based on a microwave oven of 800w and should be adjusted to suit the power of the microwave being used. If further heating is desired, use only short bursts of 10 seconds checking carefully and repeatedly until desired heat is reached. Keep a constant watch whilst heat pack is being heated and do not leave unattended. Carefully check that the headted or cooled pack feels comfortable against the skin. Remove immediately with any discomfort. Both extreme cold and extreme heat can cause injury or damage to skin. Once heated to desired temperature for use - do not re-heat with a microwave until pack has fully cooled to room temperature. To heat with hot water - partially fill a suitable container with enough hot water to fully immerse the heat pack. Carefully check the pack for the desired temperature around 5 minutes, replacing the hot water if necessary. Do not heat the water whilst the pack is immersed within it, always remove the heat source before immersing the pack or use a separate container. Take care with hot water water to avoid scalding injury and keep children well clear at all times. To avoid injury do not apply heated or cooled pack directly to skin. Always cover with a towel or cloth. To clean wipe carefully with a damp cloth only. Allow to dry naturally or wipe with a soft cloth. Discard sensibly once cover becomes soiled or damaged. Should the pack become overheated or show any signs of scorching, fumes or burning carefully remove from microwave using a suitable metal implement and place in a sink or metal bucket containing water. In this event keep children and pets well clear. Sensibly discard the item once cooled and do not re-used. This item can be safely disposed of along with your usual household refuse and is not recyclable.
