We recommend using a protective barrier such as a cloth or a piece of glass between the unit and the surface to reduce the risk of damage and/or staining. •Caution: Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type. 3 • Warning: There is a danger of explosion if you attempt to charge standard alkaline batteries in the unit. only use rechargeable NIMH batteries. • Battery shall not be exposed to excessive heat such as sunshine, fire or the like. • Caution marking is located at the rear or bottom of the apparatus. • The marking information is located at the rear or bottom of the apparatus. • Keep new and used batteries away from children. If the battery compartment does not close securely, stop using the product and keep it away from children. • If you think batteries might have been swallowed or placed inside any part of the body, seek immediate medical attention. • Do not mix old and new batteries. • Completely replace all old batteries with new ones. • Do not mix alkaline, standard (carbon-zinc), or rechargeable (ni-cad, ni-mh, etc) batteries. •Batteries should be recycled or disposed of per state and local guidelines. • WARNING: This product may contain chemicals known to the state of California to cause birth defects, or other reproductive harm (California Prop 65). Wash hands after handling. • This product meets and complies with all Federal regulations. Warning: Do NOT INGEST BSTTERY, Warning: To reduce the risk of electric shock, do not remove cover (or back). NO user-serviceable parts inside. Refer RISK servicing to qualified service personnel The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. 4 The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. This symbol indicates that this product incorporates double insulation between hazardous mains voltage and user accessible parts. This product utilizes a Class 1 laser to read Compact Discs.

See KDB 447498 D01 General RF Exposure Guidance v05, section 4.3.1. The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, 16 where ·f(GHz) is the RF channel transmit frequency in GHz ·Power and distance are rounded to the nearest mW and mm before calculation17 ·The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. Dongguan Nore Testing Center Co., Ltd.
