Recycling Information

The RBRC (Rechargeable Battery Recycling Corporation) Recycle seal on KENWOOD Ni-MH and Li-ion battery packs indicates KENWOOD's voluntary participation in an industry program to collect and recycle these batteries after their operating life has expired. This program offers an alternative to disposing of batteries with regular refuse, which is illegal in some areas. For information on Ni-MH or Li-ion battery recycling in your area, call 1-800-8-BATTERY (1-800-822-8837). KENWOOD's involvement supports environmental preservation and resource conservation.

Precautions

Observe the following precautions to prevent fire, personal injury, and transceiver damage:

Do not charge the transceiver and battery pack when they are wet.
Ensure no metallic items are between the transceiver and the battery pack.

General RF Exposure Information (Occupational Use)

This KENWOOD transceiver has been tested and complies with standards regarding Radio Frequency (RF) energy and electromagnetic energy (EME). RF exposure limits for Occupational Use Only are based on recommendations from national and international standards bodies. This transceiver generates RF EME while transmitting, which can cause slight thermal effects. RF exposure is minimized by maintaining distance from the antenna, using the lowest possible power, and keeping transmission time to a minimum. The transceiver is designed and classified for Occupational Use Only, meaning users must be aware of potential hazards and how to minimize them.

Safe Operation Practices:
While transmitting (PTT or VOX enabled), keep the antenna and radio at least 3 cm (1 3/16 inches) from your body or face, and from bystanders. A red LED indicates transmission.
Do not transmit for more than 50% of the total transceiver use time, as this may exceed FCC RF exposure limits. Typical operation is 5% transmit, 5% receive, 90% standby.
Use only the specified KENWOOD antenna or one authorized by KENWOOD.
Use only KENWOOD authorized accessories. When worn on the body, use a KENWOOD-recommended clip or carrying case. Using unapproved accessories may exceed FCC occupational RF exposure limits.

Electromagnetic Interference Compatibility

Electronic devices can be susceptible to electromagnetic interference (EMI). This transceiver, generating RF energy, can cause interference. Turn OFF your transceiver where signs indicate to do so, such as in hospitals or healthcare facilities, and on aircraft as instructed by crew. Use of the transceiver on aircraft must comply with airline regulations.
