been properly sent to the base or Access Point, the scanner issues an error
indication. You must then check to see if the scanned data was received by the
host system.
RF (Radio Frequency) Module Operation
The cordless system uses a two-way Bluetooth® radio to transmit and receive
data between the scanner and the base or Access Point. Designed for point-to-
point and multipoint-to-single point applications, the radio operates using a
license free ISM band, which sends relatively small data packets at a fast data
rate over a radio signal with randomly changing frequencies, makes the cord-
less system highly responsive to a wide variety of data collection applications
and resistant to noisy RF environments. Bluetooth Class 2 power level provides
a communication range of 33 feet (10m) between the scanner and base or
Access Point, depending on the environment. See
Flexible Power
Management , page 3-15, for information about controlling this range.
System Conditions
The components of the cordless system interact in specific ways as you associ-
ate a scanner to a base or Access Point, as you move a scanner out of range,
bring a scanner back in range, or swap scanners between two cordless sys-
tems. The following information explains the cordless system operating condi-
tions.
Linking Process
Once a scanner is placed into a cordless charge base, the scanner’s bat-
tery charge status is checked, and software automatically detects the scan-
ner and links it to the base depending on the selected link mode.
Refer to Linking the Scanner to an Access Point , page 3-2, for information
about linking to an Access Point.
