Type approval
Type approval, or acceptance, covers technical parameters of the equipment related to emissions
that can cause interference. Type approval is granted to the manufacturer of the transmission
equipment, independent from the operation or licensing of the units.
Some countries have unique technical requirements for operation in particular radio-modem
frequency bands. To comply with those requirements, Trimble may have modified your equipment
to be granted Type approval.
Unauthorized modification of the units voids the Type approval, the warranty, and the operational
license of the equipment.

Safety. Exposure to RF energy is an important safety consideration. The FCC has adopted a safety
standard for human exposure to radio frequency electromagnetic energy emitted by FCC regulated
equipment as a result of its actions in General Docket 79-144 on March 13, 1986.
