Warning for Use of Wireless Devices Please observe all warning notices with regard to the usage of wireless devices. Potentially Hazardous Atmospheres You are reminded of the need to observe restrictions on the use of radio devices in fuel depots, chemical plants etc. and areas where the air contains chemicals or particles

(such as grain, dust, or metal powders) and any other area where you would normally be advised to turn off your vehicle engine. Switch off your wireless device whenever you are instructed to do so by airport or airline staff. Safety in Aircraft Pacemakers Pacemaker manufacturers recommended that a minimum of 15cm (6 inches) be maintained between a handheld wireless device and a pacemaker to avoid potential interference with the pacemaker. These recommendations are consistent with independent research and recommendations by Wireless Technology Research. Persons with Pacemakers breast pocket . Persons with Pacemakers should ALWAYS keep the device more than 15cm (6 inches) from their pacemaker when turned ON and hence they should not carry the device in a Should use the ear furthest from the pacemaker to minimize the potential for interference.

Battery Information Our rechargeable battery packs are designed and constructed to the highest standards within the industry. However, there are limitations to how long a battery can operate or be stored before needing replacement. Many factors affect the actual life cycle of a battery pack, such as heat, cold, harsh environmental conditions and severe drops. When batteries are stored over six (6) months, some irreversible deterioration in overall battery quality may occur. Store batteries discharged in a dry, cool place, removed from the equipment to prevent loss of capacity, rusting of metallic parts and electrolyte leakage. When storing batteries for one year or longer, they should be charged and discharged at least once a year. If an electrolyte leakage is observed, avoid any contact with affected area and properly dispose of the battery. Batteries must be charged within v the 32 to 95 F (0 to +35 C) ambient temperature range. Replace the battery when a significant loss of run time is detected. Battery Caution Risk of explosion if battery is replaced by an incorrectly type. Dispose of used battery according to the local disposal instructions. Waste Electrical and Electronic Equipment (WEEE) English: For EU Customers: All products at the end of their life must be returned to the reseller for recycling.
