2. Safety Information

RF Radiation Information

This product is intended solely for professional use where RF energy radiation requirements can be met. Users must be fully aware of RF radiation hazards and take appropriate measures to comply with RF radiation limits.

RF Radiation Basics

RF (Radio Frequency) refers to electromagnetic frequencies that can radiate into space. It is a technology widely used in fields such as communications, medical, and food processing, and it generates a certain amount of RF radiation during use.

FCC Regulatory Requirements

In accordance with the regulations of the Federal Communications Commission (FCC) of the United States, this product must comply with FCC RF radiation limits to be sold in the U.S. market. Manufacturers are required to inform users of important safety precautions by labeling the product, thus enhancing user awareness of radiation protection.

RF Radiation Safety

To ensure the health and well-being of users, experts from the fields of science, engineering, medicine, health, and industry, along with relevant organizations, have jointly developed RF radiation standards and guidelines, as follows:

• Title 47, Part 2, Subpart J of the Code of Federal Regulations (CFR) by the Federal Communications Commission (FCC) of the United States.
• ANSI (American National Standards Institute) / IEEE (Institute of Electrical and Electronics Engineers) Standard C95.1-1992.
• IEEE Standard C95.1-1999.
• Standards issued in 1998 by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).

RF Radiation Control and Operating Instructions

To ensure optimal performance and compliance with the radiation limits for occupational or controlled environments as specified in the standards, the transmission time should not exceed a duty cycle of 50% (i.e., a maximum of 50% transmission time). Adhere to the following instructions: RF energy radiation is only generated during transmission (talking), not during receiving (listening) or standby mode. Maintain a minimum distance of 2.5 centimeters between the device and the body during transmission.

4.7 Cross Band Repeater Setup

The cross-band repeater function allows the radio to connect different frequency bands (U/V bands) to extend communication range.

1. Activating Repeater Mode: Navigate to Menu → Radio → AB RPT-Mode → ON. The standby screen will display the repeater icon【Z】.
2. Repeater Requirements: Devices enabling the relay function must operate on different frequency bands.
3. Repeater Direction Logic:
   • Default Standby State: Both primary and secondary frequencies act as receivers.
   • If the primary frequency first receives a valid carrier signal, the secondary frequency automatically becomes the cross-band transmitter.
   • If the secondary frequency first receives a valid carrier signal, the primary frequency automatically becomes the cross-band transmitter.
4. Speaker Audio Control: Configure the option to enable/disable local speaker audio during repeater operation.
