Retevis RT97 - User Manual

The Retevis RT97 Repeater is a robust and versatile communication device designed to extend the range and improve the clarity of radio signals in various environments. It serves as a signal booster, receiving weak radio signals and retransmitting them at a higher power, thereby enlarging the communication range for connected transceivers. This makes it an ideal solution for areas where direct radio communication might be challenging due to distance, obstacles, or signal attenuation.

Function Description:

The primary function of the RT97 Repeater is to facilitate two-way radio communication over extended distances. It operates by receiving signals on one frequency (RX frequency) and simultaneously transmitting them on a different frequency (TX frequency). This duplex operation allows for continuous communication without the need for manual switching between transmit and receive modes on the repeater itself. The device is capable of being programmed with up to 16 channels, offering flexibility in managing different communication groups or frequencies.

The repeater enhances weak signals, converting them into strong, clear transmissions. This is particularly beneficial in challenging environments such as underground parking lots, multi-story buildings, "dead zones" in hotels or entertainment venues, and for coordinating moving fleets or operations in mining, ports, and forested areas. By boosting the signal, the RT97 ensures reliable and efficient communication, which is crucial for safety and operational efficiency in many professional settings.

Usage Features:

The RT97 Repeater is designed for straightforward operation and flexible deployment.

• Easy Setup and Operation: To power on the repeater, simply connect the adapter to a power supply. The screen will illuminate, indicating it's ready for use. To turn it off, disconnect the adapter. Channel selection is intuitive, allowing users to switch between the 16 programmed channels using the "+" and "-" buttons. A short press on these buttons increases or decreases the channel number, while a long press can indicate the current channel's CTCSS/DCS frequency or lock/unlock the keypad.
• Display and Indicators: The repeater features an LCD screen that displays various icons representing selected functions, including channel number, frequency, CTCSS/DCS settings, narrow band status, high/low power indication, and key lock status. This visual feedback helps users monitor the repeater's operational state.
• Flexible Installation: The RT97 can be operated as a fixed or mobile unit, offering versatility in its application. It is recommended to install the repeater in a safe, convenient, and well-ventilated location, away from direct sunlight, to ensure optimal performance and longevity.
• Antenna Connection: For successful operation, a highly and precisely tuned antenna must be installed. The quality of the antenna system and correct installation are critical for achieving perfect operation results and maximizing the repeater's range. When installing an outdoor antenna, a lightning arrester must be installed first and then connected to the antenna, with the chassis reliably grounded to prevent lightning damage.
• Power Options: The repeater supports multiple working power selections. It can operate with its matching power adapter or under a DC12V~24V power supply, including car power, making it adaptable to different power sources and environments.
• Application Versatility: The RT97 is suitable for a wide range of applications where communication range extension is needed. This includes improving signal coverage in underground parking lots and multi-story buildings within property communities, eliminating "dead zones" in hotels, KTVs, and other entertainment venues, maintaining communication between front and rear vehicles in moving fleets, and ensuring reliable communication in industrial settings like mining, ports, and forestry operations.

Maintenance Features:

The RT97 Repeater is built for durability and ease of maintenance, with specific guidelines to ensure its longevity and safe operation.

• Robust Construction: The device is described as small, compact, solid, and dust-proof, indicating a design intended to withstand various environmental conditions and offer a long service life.
• Professional Maintenance: Maintenance of the repeater should only be performed by professional technicians. Self-disassembly is strictly prohibited to prevent damage to the device and ensure its proper functioning.
• Environmental Considerations: To maintain optimal performance and safety, the repeater should not be placed in wet, rainy, or excessively dusty areas. It should also be kept away from direct sunlight for extended periods and heating devices.
• EMC Compliance: To avoid electromagnetic compatibility (EMC) interference or compliance issues, the repeater should not be installed or used in areas where "Please Turn Off the Radio" labels are present. This also extends to areas with airbags in vehicles, where the repeater should not be installed in a way that could interfere with airbag deployment.
• Safety Precautions: Users are forbidden from operating the repeater in flammable and explosive environments. When approaching blasting areas or detonators, the repeater must be turned off immediately. These precautions are crucial for preventing accidents and ensuring the safety of personnel and equipment.
• Software and Hardware Updates: The company reserves the right to upgrade or improve the product, including changes to software and hardware specifications, without prior notice. This indicates a commitment to continuous improvement, though users should be aware that future versions may have updated features or performance characteristics.
• Warranty and Support: The product typically comes with a two-year manufacturer's warranty. Users are advised to keep the guarantee card and purchase vouchers for verification. Support can be obtained by contacting the seller or a local repair center. Exclusions from warranty coverage include accidental damage, misuse, unauthorized alterations, or if the serial number has been tampered with.

In summary, the Retevis RT97 Repeater is a reliable, user-friendly, and robust device designed to significantly enhance radio communication range and clarity across diverse operational environments, supported by clear usage guidelines and professional maintenance recommendations.
