IMAGETEAM™ 2020/5620 System Manual 1 - 11
a radio signal with randomly changing frequencies, makes the cordless system
highly responsive to a wide variety of data collection applications and resistant to
noisy RF environments. Bluetooth Class 2 power level provides range of 33 feet
(10m) depending on the environment.
Cordless Scanner
The cordless scanner enables fast and accurate bar code scanning using a non-
contact linear imager.
The scanner is comprised of a linear imager, a decode/control assembly, and an
RF communication module. The scan engine performs the bar code image
illumination and sensing. The decode/control assembly coordinates the central
communication activities including: capturing and decoding the bar code image
data, performing software activities (parameter menuing, visual indicator
support, low battery indication), and data translation required for the host system.
The RF communication module performs the data exchange between the
scanner and the base.
System Conditions
The components of the cordless system interact in specific ways as you
associate a scanner to a base, as you move a scanner out of range, bring a
scanner back in range, or swap scanners between two cordless systems. The
following information explains the cordless system operating conditions.
Linking Process
Once a scanner is placed into the base, the scanner’s battery charge status is
checked, and software automatically detects the scanner and links it to the base
if another scanner is not already linked.
Scanner Is Out of Range
The cordless scanner is in communication with its base, even when it is not
transmitting bar code data. Whenever the scanner can’t communicate with the
base for a few seconds, it is out of range. If the scanner is out of range and you
scan a bar code, the scanner issues a triple beep indicating no communication
with the base. In addition, your scanner and base can sound an alarm if
programmed to emit an alarm. See Out-of-Range Alarm on page 1-8.
Scanner Is Moved Back Into Range
The 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.
