Cordless ScannerThe cordless scanner enables fast and accurate bar code scanning using a noncontactlinear scanner.The scanner is comprised of a linear scanner, a decode/control assembly, andan RF communication module. The scan engine performs the bar code imageillumination and sensing. The decode/control assembly coordinates the centralcommunication activities including: capturing and decoding the bar code imagedata, performing software activities (parameter menuing, visual indicatorsupport, low battery indication), and data translation required for the host system.The RF communication module performs the data exchange between thescanner and the base.System ConditionsThe components of the cordless system interact in specific ways as youassociate a scanner to a base, as you move a scanner out of range, bring ascanner back in range, or swap scanners between two cordless systems. Thefollowing information explains the cordless system operating conditions.Linking ProcessOnce a scanner is placed into the base, the scanner’s battery charge status ischecked, and software automatically detects the scanner and links it to the basedepending on the selected link mode.Scanner Is Out of RangeThe cordless scanner is in communication with its base, even when it is nottransmitting bar code data. Whenever the scanner can’t communicate with thebase for a few seconds, it is out of range. If the scanner is out of range and youscan a bar code, the scanner issues a triple beep indicating no communicationwith the base. In addition, your scanner and base can sound an alarm ifprogrammed to emit an alarm. See Out-of-Range Alarm on page 1-13.Scanner Is Moved Back Into RangeThe scanner re-links if the scanner or the base have been reset or out of range.If the scanner re-links, you will hear a single chirp when the re-linking process(uploading of the parameter table) is complete.Out of Range and Back into Range with Data Accumulation ModeOnThe scanner may store a number of symbols (approximately 500 UPC symbols,others may vary) when out of range and then send them to the base when backin range. You will not hear a communication error beep in this mode, but you willhear a short buzz when you pull the trigger if the radio communication is notworking. Once the radio connection is made, the scanner produces a series ofbeeps while the data is being transferred to the base.2020/3820 User’s Guide 1 - 17
