Beifeng BF-508 analog handheld walkie-talkie integrates the advantages of Beifeng's previous analog products to further improve product performance。It integrates 4000mAh large-capacity battery, dual-guard and dual-power working channel, one-button quick reply, multiple flashlight modes, voice encryption, customized noise reduction and many other advantages,Equipped with monitoring, scanning, busy channel lock, low power reminder and other general functions,Smart yet steady black business look,It has become a good partner for industrial and commercial users such as engineering construction, security, and hotels。
Long endurance intelligent power saving
BF-508 is equipped with 4000mAh super-large capacity polymer battery, which can be ultra-long standby for 300 hours and continuous talk for 29 hours, ensuring the stable connection of industrial and commercial users three shifts a day。When no signal is received or there is no operation, support voice broadcast low power prompt and power saving ratio setting, fully extend the battery life time, and provide sufficient and stable power supply for calls。
Double guard double fire efficient communication
The BF-508 has dual wait and dual launch functions。The main/sub-channel adopts double button design, and the dual-waiting function can work in multiple groups at the same time, which is suitable for the work communication needs of multi-group and multi-department industrial and commercial users。 In the event of special and emergency situations,Dual-channel waiting can also realize a channel listening to the main call channel,One channel for the emergency call signal,Avoid omission of key information;In addition,The user does not need to manually determine which channel the received signal is coming from,Press any PTT key within the specified time to automatically reply to this message,Quick reply with one click,Achieve communication efficiency。
Strong light flash safety and practical
The BF-508 can turn on the LED concentrating flashlight function with one button, and has 3 modes: steady on/normal fast blinking /SOS emergency fast blinking。In the dark environment, the super brightness of the flashlight lighting function can replace the flashlight to solve the urgent problem and help users expand their vision;SOS flash mode, easy to transmit distress signal in emergency, but also to provide users with a layer of security。
Voice encryption High security
The BF-508 takes the confidentiality of communications into account。Beifeng speech codec technology and data encryption technology,Completely eliminate the risk of intentional eavesdropping or information leakage caused by crosstalk,Truly realize source level end-to-end encryption protection for intercom users,Help users achieve high security confidential calls at a lower cost,To meet the industrial and commercial customers in different application scenarios for wireless intercom security requirements。
Custom noise reduction eliminates noise
The BF-508 supports custom squelch level Settings to achieve good listening effects according to changes in the use environment。Combined with advanced speech compression technology, further suppress environmental noise interference, improve the clarity of transmitted and received speech, especially suitable for use in noisy environments, to ensure that each call is clear and clear。
PC+ABS material is strong and durable
The BF-508 shell is made of PC+ABS material, which is durable and has good drop resistance and wear resistance。The back is equipped with elastic fixed back clip, PC material toughness is better, convenient for users to wear directly in the waist or clothing pocket;The top double knob design is full of damping and easy to operate。
Compact appearance easy to master
The overall design of the BF-508 demonstrates Beifeng's pursuit of quality。All black business appearance atmosphere calm, simple streamline design fashion exquisite, the size is just right, one hand can be operated, holding the handshake feeling more comfortable。For industrial and commercial user groups, beautiful and easy to carry, the operation is more convenient。
