1 REGULATORY INFORMATION
1.1 Human Exposure Compliance Statement
Pursuant to 47 CFR § 24.52 of the FCC Rules and Regulations, personal communications services (PCS)
equipment is subject to the radio frequency radiation exposure requirements specified in § 1.1307(b), §
2.1091 and § 2.1093, as appropriate.
CalAmp and its supplier certify that it has determined that the TTU-7xx complies with the RF hazard
requirements applicable to broadband PCS equipment operating under the authority of 47 CFR Part 24,
Subpart E of the FCC Rules and Regulations. This determination is dependent upon installation,
operation and use of the equipment in accordance with all instructions provided.
The TTU-7xx is designed for and intended to be used in fixed and mobile applications. “Fixed” means
that the device is physically secured at one location and is not able to be easily moved to another
location. “Mobile” means that the device is designed to be used in other than fixed locations and
generally in such a way that a separation distance of at least 20 cm is normally maintained between the
transmitter’s antenna and the body of the user or nearby persons. The TTU-7xx is not designed for or
intended to be used in portable applications (within 20 cm of the body of the user) and such uses are
strictly prohibited.
To ensure that the TTU-7xx complies with current FCC regulations limiting both maximum RF output
power and human exposure to radio frequency radiation, a separation distance of at least 20 cm must
be maintained between the unit’s antenna and the body of the user and any nearby persons at all times
and in all applications and uses. Additionally, in mobile applications, maximum antenna gain must not
exceed 3 dBi.
1.2 Hardware Precautions
Electrical Over-Stress (EOS)
The TTU-7xx GPS receiver can be damaged if exposed to an RF level that exceeds its maximum input
rating. Such exposure can happen if a nearby source transmits an RF signal at sufficiently high level to
cause damage.
Storage and Shipping
One potential source of EOS is proximity of one TTU-7xx device to another TTU-7xx device. Should one
of the units be in a transmit mode, the potential exists for the other unit to become damaged.
Therefore, any TTU-7xx should be kept at least four inches apart from any active TTU-7xx or any other
active high power RF transmitter with power greater than 1 Watt.
