MS3390 Mobile Scanner Quick Guide 

)

 

A standard packing includes a mobile scanner, a USB cable and a CD (containing software 
and electrical manuals).  Optional accessory includes a Bluetooth USB adapter BA2110 
which supports reliable wireless data transmission and an AC/DC adaptor for battery charge.

)

 

The term “scanner” as used in this guide denotes the mobile scanner. 

)

 

Use dry and soft cloth to clean the scanner. 

)

 

Effective communication range: The communication distance is 30 meters under the 
condition of temperature at 27 degrees Celsius, sunny day, and visibility of 5 kilometers. 
Natural surroundings significantly affect the communication distance in practice. The 
distance drops quickly in the rainy, high-humidity, or heavy haze day; radio interference also 
shortens the communication distance. 

)

 

Bluetooth uses the 2.4 GHz ISM frequency band.    The WLAN also uses the same one.    So 
the coexistence of the scanner and WLAN may cause a strong decline in the effective 
communication range. 

)

 

The scanner provides a variety of wireless communication modes, and supports batch data 
mode and U disk mode.    It is suggested to read the user manual in details before use.
