Description

Low Power Consumption and Long-Distance Solution: Retevis RB91 Digital Repeater + 2PCS RB24 UHF Handheld Radio Retevis RB91 wall-mounted digital repeater has strong penetrating power, which can enhance the signal and expand the signal coverage. It has a built-in 15000mAh battery, which can achieve 7 days of standby. Retevis RB24 handheld radio comes with a repeater function, can automatically form a network, and can jump continuously up to 30 levels to meet the ultra-long communication distance in areas without signals. This communication solution includes a RB91 repeater and 2 packs of RB24 handheld radios. It has low power consumption and wide coverage. It can ensure a stable connection even in closed areas such as basements, subways and tunnels. Long-Distance Solution Using the RB91 digital repeater to work with the RB24 digital walkie talkies can greatly improve signal transmission and reception, significantly extending the range of communication. This solution can achieve long-distance communication, even in areas with poor signal strength like basements, subways, and tunnels. Strong Penetration RB91 digital repeater and the RB24 digital handheld radio have a built-in LoRa (Long Range) Modulation, which features strong pene- tration and realizes ultra-long distance reception. It performs well in different scenarios, such as rescue support and subways, buildings, and tunnels. Connect up to 30 Radios Retevis RB24 handheld digital radio comes with a repeater function, can automatically form a network, and can continuously connect up to 30 radios to meet the ultra-long communication distance in areas without signals. Built-in 15000mAh Battery (Repeater) Equipped with a 15000mAh battery, the base station provides a standby time of 7 days and a working time of 10 hours. This ensures that the base station can be used throughout the day without the need for frequent charging. Solar Charging (Repeater) Retevis RB91 repeater not only supports regular AC charging but also supports solar charging via a 12V (solar) charging port, which is perfect for field settings where electrical power is non-existent or unreliable. Easy to Operate RB24 handheld two way radios can directly work with the RB91 direct frequency base station without complex setup, which is easy to use. (RB91 base station is only compatible with RB24 digital handheld radio.) Superior Audio Quality RB91 digital repeater and RB24 digital two way radio use digital technology to provide clearer and more understandable digital audio, achieving clear call quality in closed basements. All Call The digital walkie talkie enables continuous connectivity with team members on the same designated channel, significantly enhancing communication efficiency. Various Applications This communication solution can enhance the signal and extend the signal coverage. It is the perfect communication solution for places with weak signals such as tunnels, buildings, basements, subways, forests, and rescues.

Use the equipped screws and hole to hang on the wall Installation Attentions: 1.Electromagnetic affection source: •Avoid being close to sources of strong electromagnetic fields, such as high-power radio transmitting stations, radar stations, high-voltage transmission lines, etc. These may produce severe electromagnetic affection on the normal operation of relay equipment. 2. Physical obstacles: •The installation location should try to avoid high-density buildings, large metal structures (such as elevator shafts, and reinforced concrete walls), mountains, high-rise buildings, etc. These obstacles will block or attenuate wireless signals. 3. Co-channel affection: •Other wireless devices using the same or similar frequencies, such as other wireless walkie-talkie relays, wireless devices, etc., may cause co-channel affection. Frequency resources need to be planned appropriately to avoid overlap. 4. Water source and humid environment: •Avoid installing directly near water sources, such as water towers, lakes, rivers, etc., and places with high humidity to reduce the risk of equipment corrosion and short circuit caused by moisture. 5. High and low-temperature environments: •The equipment should not be installed in places where the temperature is too high or too low. Extreme temperatures may cause performance degradation or damage to electronic components. Ensure that the equipment operates within the appropriate temperature range specified by the manufacturer.
