M40e Router Environmental Specifications on page 271
Table 26 on page 271 specifies the environmental conditions required for normal router
operation. In addition, the site should be as dust-free as possible. Dust can clog air intake
vents and filters, reducing cooling system efficiency. Check the filters and vents frequently,
cleaning them as necessary. For more information, see "Routine Maintenance Procedures
for the M40e Router" on page 129.
