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.
