Socket Cordless Ring Scanner Series 9 User Manual page 82

Scanning Distance
• The optimal scanning distance varies depending on the barcode size, symbology,
label media, W-N Ratio, and scan angle. In general, the Bluetooth CRS 9P can
successfully scan 1.5 to 45+ inches (3.8 to 144 cm) from the barcode.
• The larger the barcode, the further away you should position the scanner.
The thinner the bars of the barcode (more dense), the closer you should hold the
scanner.
About Bluetooth and Health
Bluetooth wireless technology allows you to use short-range radio signals to connect
a variety of devices, such as barcode scanners, mobile phones, Pocket PCs, notebook
computers, printers, and many other devices at home or work. These radio signals
replace the cables that have traditionally connected these devices.
Bluetooth products have small radio transmitters and receivers. Output power is
normally very low, only 1 mW (1/1000 of a watt). This gives a working range of
approximately 10 meters.
The maximum exposure levels from Bluetooth products are far below recommended
safety guidelines. At most, typical Bluetooth devices (1mW) reach only one percent
of the prescribed safety levels.
Product Care
• Do not expose the product to liquid, moisture or extreme humidity.
• Do not expose the product beyond storage temperatures of -40 to +158°F (-40 to
+70°C) and do not operate product beyond temperatures of -4 to +140°F (20 to
+60°C).
• Do not expose the product to lit candles, cigarettes, or cigars, or to open flames,
etc.
• To keep pin contacts clear of dust or deposits, clean pin contacts (5 on wrist unit,
4 on ring unit) with alcohol solution using cotton swabs or alcohol wipes
periodically (every week as needed).
• Do not drop, throw or try to bend the product, as rough treatment can damage it.

Antenna Care
Do not place a metallic shield around the Bluetooth CRS since it will reduce the
radio transmission efficiency.
Efficient Use
For optimum performance, make sure there is no metal surrounding the Bluetooth CRS.
