Airport Security and Your eSight 3
At airport security, you may be asked to remove your eyewear as part
of the security screening process. Inform the security officer that you
have low vision and may require assistance with the screening process.
If you travel with supporting documentation describing your medical
condition, present it to officer. Politely ask the officer to reunite you
with your eyewear immediately after it is screened.
Class 1 Laser Product
This device contains a Class I Laser Product.
Product Emissions Compliance
This equipment generates, uses, and can radiate radio frequency
energy. It also contains rare-earth magnets. The equipment may cause
radio frequency or magnetic interference to other devices and radio
communications.

changes or modifications to this equipment. Changes or modifications
are not authorized.
Wireless Adapter Regulatory
Information
Use on Aircraft
Caution
FCC and FAA regulations may prohibit airborne operation of radio-
frequency wireless devices (wireless adapters) because their signals
could interfere with critical aircraft instruments. Ask the cabin crew
before turning on the wireless adapter while on board.

Important Safety Information
13
Wireless Adapter and Your Health
The wireless adapter, like other radio devices, emits radio frequency
electromagnetic energy. The level of energy emitted by the eSight
wireless adapter is less than the electromagnetic energy put out by
other wireless devices such as mobile phones. The wireless adapter
operates within the guidelines of radio frequency safety standards and
recommendations. These standards and recommendations reflect the
consensus of the scientific community who continually review and
interpret the extensive research literature.
In some situations, the use of the wireless adapter may be restricted by
the building owner or organization representative.
Examples of such situations include
• Using the wireless adapter on-board airplanes, or
• Using the wireless adapter in any environment where the risk of
interference with other devices is perceived as being harmful.
If you are uncertain of the policy that applies to the use of wireless
adapters where you are (an airport, for example), ask for authorization
to use the adapter before you turn it on.
FCC Specific Absorption Rate (SAR) Certification Information
The FCC with its action in ET Docket 96-8 has adopted a safety
standard for human exposure to radio frequency (RF) electromagnetic
energy emitted by FCC-certified equipment. The wireless adapter
meets the Human Exposure limits found in OET Bulletin 65.
