Do not touch the surface of your Grid Pad with broken or burnt
skin as this may aggravate wound.
Power supply and batteries
Your Grid Pad contains a rechargeable lithium ion battery. All
rechargeable batteries degrade over time. The usage time for a
Grid Pad after a full charge can become shorter over time.
For optimal performance, your Grid Pad should not be charged at
extreme temperatures of below 0°C (32°F) or above 45°C (113°F).
At these temperatures your battery will charge slowly or not at all.
Do not expose your Grid Pad to fire or temperatures above 90°C
(194°F) as these conditions can cause the battery to malfunction,
ignite or explode. Please take care when storing your Grid Pad.
Only charge your Grid Pad with the supplied power cord. Using
unofficial power supplies may cause severe damage to your
Grid Pad and cause fire. If your Grid Pad's power lead is lost or
damaged, contact your supplier.
