采用UHF超高频段，比传统的VHF频段干扰更少，传输更可靠
DPLL数字锁相环多信道频率合成技术，在50MHZ频率范围内，
以250KHZ信道间隔，提供多达200个信道选择，方便多套机器
同时使用,轻松避开各类干扰；先进的自动对频技术，即使将发
射机与接收机的频率调乱了，只需轻轻一按,发射机就会自动追
锁频率并调整一致，使用方便高档液晶显示屏，使接收机及发
射器的工作状态一目了然；无线会议发射系统，采用两节AA电
池供电，采用高碱性电池可使用较长时间(高功率8小时，低功
率12小时)。若使用充电电池，使用时间会有所下降。
UHF ultra-high frequency band, less interference than traditional VHF band, more
reliable transmission DPLL digital phase-locked loop multi-channel frequency
synthesis technology, in the 50 MHZ frequency range, with 250 KHZ channel
interval, provides up to 200 channel choices, convenient for multiple sets of
machines to use at the same time, easily avoid all kinds of interference; advanced
automatic frequency matching technology, even if the frequency of transmitter and
receiver is disordered, only need to press lightly, Transmitter will automatically lock
frequency and adjust the same, easy to use high-end LCD display, so that the
working status of the receiver and transmitter can be seen at a glance; wireless
conference transmission system, using two AA batteries, using high alkaline batteries
can be used for a long time (high power 8 hours, low power 12 hours). If rechargeable
batteries are used, the usage time will decrease.
