RF Radiation Information

This product is intended 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 communications, medical, and food processing, and it generates a certain amount of RF radiation during use.

FCC Regulatory Requirements

This product complies with FCC RF radiation limits for the U.S. market. Manufacturers are required to inform users of important safety precautions by labeling the product to enhance user awareness of radiation protection.

RF Radiation Safety

To ensure user health and well-being, experts have developed RF radiation standards and guidelines. These include Title 47, Part 2, Subpart J of the Code of Federal Regulations (CFR) by the FCC, ANSI/IEEE Standard C95.1-1992, IEEE Standard C95.1-1999, and 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 radiation limits for occupational or controlled environments, the transmission time should not exceed a duty cycle of 50%. 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.

• Press [BOK] again to confirm selections.
• Press [<] to exit the menu.

Primary/Secondary Frequency Toggle

On the standby screen, briefly press the [<] key to select the primary frequency (highlighted in blue background). Non-highlighted frequencies are secondary.

Channel Mode / Frequency Mode Toggle

On the standby screen, briefly press the [V/M] key to switch between frequency mode and channel mode. Note: If no valid channels are stored, switching to Channel Mode is disabled.

Side Key Configuration

Configure side key functions via programming software. Supported functions include RADIO, MONI, SCAN, SEARCH, SOS, SPECTRUM, and Beacon TX.

Voice-Activated Transmission (VOX) Function

• Operation: Menu → VOX.
• When enabled, the radio automatically enters transmit mode if the microphone detects sufficient sound input.
• Adjustable VOX sensitivity level via menu settings.
• VOX delay time must be configured to maintain transmission continuity.

Sweep Function

• Assign the side key function as "Sweep" or long-press [>] to quickly enter sweep mode.
• It detects the transmitter's carrier frequency and CTCSS/DCS (sub-tone) information, displaying them on the screen.
• Once the carrier frequency is detected, press the [BOK] key to save the scanned frequency to a specified channel list.
• Supported Ranges: VHF: 136-174 MHz, UHF: 400–520 MHz.

Repeater Setup

• 1. Activating Repeater Mode: Menu → Radio → AB RPT-Mode → ON. Standby screen displays 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 primary frequency receives a valid carrier signal: Secondary frequency automatically becomes the cross-band transmitter.
  • If secondary frequency receives a valid carrier signal: Primary frequency automatically becomes the cross-band transmitter.
• 4. Speaker Audio Control: Configurable option: Enable/disable local speaker audio during repeater operation.

Emergency SOS Function

• Assign a side key as the [Emergency Alarm] button.
• Operation: Menu → Radio → SOS Mode.
• Local Alarm: The device sounds an alarm tone locally without transmitting any signal.
• Transmit Alarm Tone: Broadcasts the alarm tone via signal transmission.
• Transmit Alarm Code: Sends the alarm code through signal transmission.

CTCSS/DCS Settings

• Operation: Menu → CTCSS/DCS, Select desired DCS code or CTCSS frequency.
• Function: Enables selective call reception by filtering out unwanted noise signals.

Scan Function

• Side Key Shortcut: Assign a side key as the Scan Key.
• Configure via: Menu → Radio → Scan Mode.
• Channel Mode: Scans the channels listed in the channel memory (requires power-on scan to add).
• Frequency Mode: Scans frequencies based on the selected step Setting.
• Time Mode: Resumes scanning if no operation is performed within 5 seconds after detecting a carrier signal.
• Carrier Mode: Stops scanning upon detecting a carrier signal and resumes scanning 5 seconds after the carrier disappears.
• Search Mode: Stops scanning immediately upon detecting a carrier signal.

PTT-ID Function

DTMF transmit identity S-CODE or PTT-ID.

• Call Codes (15 preset groups): Menu → Signaling → S-CODE. Assign unique call codes to each segment (A/B/C) or signal type.
• ID Code Setup: Menu → Signaling → PTT-ID.
• Transmission Modes:
  • Send on Press: After pressing the PTT, the call code/identity code is sent first, followed by the voice signal.
  • Send on Release: After releasing the PTT, the call code/identity code is sent, then the transmission ends.
  • Send Both: The call code/identity code is sent both when the PTT is pressed and released.
• Note: Since the identity code operation is independent of the call code, if there is a conflict between the identity code and the call code settings, the identity code will be sent.

FM Radio Function
