Determine Scanner Location 
When identifying a location for the 7893 scanner, consider the length of the connecting cables. 
The electrical outlet used for the Power Module can be approximately 74 in. (188 cm) from the 
host terminal. Depending on the Scanner Module Cable, the scanner can be approximately 9 ft. 
(274 cm), 6.6 feet (2 meters) or 13.1 feet (4 meters) from the host terminal or PC. These 
distances are normally shorter depending on how you route the connecting cables. Be sure that 
the Scanner Module Cable is long enough to permit the scanner to be picked up when required 
for large packages. 
Like any electronic device, the 7893 should not be located in direct sunlight. Temperatures 
above 104 degrees Fahrenheit (40 degrees Celsius) can occur when sunlight falls on objects 
through windows or on an outdoor checkstand.
