Warning – Modifications:

Changes or modifications to the internal parts not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

Warning – Blasting Area:

To avoid interference with blasting operations, turn your transmitter off when in a “Blasting Area” or in areas posted “Turn off two-way radio.” Obey all signs and instructions.

Warning – Potential Explosive Atmosphere:

Turn off the transmitter or any product with the transmitter installed when in any area with a potentially explosive atmosphere and obey all signs and instructions. (End products specifically designed to work in Explosive Atmospheres are to follow their certification guidelines.)

Warning – Pacemakers:

The Health Industry Manufacturers Association recommends that a minimum separation of six (6”) inches be maintained between the transmitter and a pacemaker to avoid potential interference with the pacemaker.

Warning – Hearing Aids:

Some digital wireless devices may interfere with some hearing aids. In order to prevent such interference, you may want to consult the manufacturer of your hearing aid.

Warning - Specific Absorption Rate (SAR):

FCC / Canada:

The transmitter has been shown to be compliant to localized Specific Absorption Rate (SAR) for uncontrolled environment/ general exposure limits specified in ANSI/IEEE STD C95.1-1992 and has been tested in accordance with measurement procedure specified in IEEE 1528-2013 and IEC 62209- 2.2010 using a separation distance of 20 cm.

European Union (CE RED):

The transmitter has been shown to be compliant for localized specific absorption rate (SAR) for uncontrolled environment / general exposure limits specified in ANSI/IEEE Std. C95.1-1999 and has been tested in accordance with the measurement procedures specified in EN50566:2017 and EN62209- 2:2010 using a separation distance of 20 cm.

NOTE: If concerned about RF exposure during use, place the transmitter away from your body. The RF exposure level drops off dramatically with distance from the antenna.
