Installation Notes     
 
Plugging the scanner into the serial port of the PC   
does not guarantee that scanned information will   
appear at the PC. A software driver and    correct   
configuration settings are also required for proper   
communications to occur.   
 
Powering the MS5145 directly from the host device   
can sometimes cause interference with the operation   
of the scanner or the computer. Not all computers   
supply the same current. For this reason, using an   
external power supply is recommended. For additional   
information, contact a customer service representative.   
 
All MS5145-00 scanners leave the factory with the   
Laser Emulation Mode enabled. If recall defaults is   
scanned while re-configuring the scanner the Laser   
Emulation Mode will no longer be enabled. Refer    to   
the MS5145-00 Laser Emulation Mode section of the   
MetroSelect Single-Line Configuration Guide for in- 
formation on enabling the Laser Emulation Mode.   
            See caution on page 5.
