RF EXPOSURE &
ELECTRICAL SAFETY COMPLIANCE
AT Commands
The use of this device in any other type of host conguration may not comply with the RF exposure
requirements and should be avoided. During operation, a 20 cm separation distance should be
maintained between the antenna, whether extended or retracted, and the user’s/bystander’s body
(excluding hands, wrists, feet, and ankles) to ensure RF exposure compliance. The modem is not
designed for, nor intended to be, used in applications within 20 cm (8 inches) of the body of the user.
Continued compliance of the equipment relies upon it being used with an AS/NZS 60950.1 approved
SELV power supply.
CAUTION
Change or modication without the express consent of Maxon Electronics Australia Pty. Ltd. voids the
user’s authority to use the equipment. These limits are designed to provide reasonable protection
against harmful interference in an appropriate installation. The modem is a transmitting device with
similar output power to a mobile phone. This equipment generates, uses, and can radiate radio
frequency energy and, if not used in accordance with instructions, can cause harmful radiation to
radio communication. Use only the supplied or an approved antenna. Unauthorized antennas, modi-
cations, or attachments could impair call quality, damage the device, or result in violation of RF
exposure regulations.
However, there is no guarantee that interference will not occur in a particular installation. If the
equipment does cause harmful interference in radio and television reception, which can be deter-
mined by turning the equipment on and o, the user is encouraged to try to correct the interference
by one or more of the following measures:
tRe-orient or relocate the receiving radio or TV antenna
tIncrease the separation distance between the equipment and the receiver
tContact Maxon Australia Technical Support for assistance.
