By simply pressing the Sync button on the receiver, the user can automatically lock any of 50 available UHF frequencies between the transmitter and receiver.

只需按下接收器上的同步按钮，用户可以自动锁定50至发射器和接收器可超高频频率。

Due to steady phase error, low-order PLL has a trouble in tracking frequency ramp signals, so that the receiver cannot lock carrier signals.

低阶锁相环跟踪频率斜升信号时产生的稳态相差致使环路失锁，接收机无法锁定载波信号。

When using GLONASS satellites, the time it takes for the receiver to "lock on" to a position is (on average) approximately 20 percent faster than using GPS. And when using both GPS and GLONASS, the receiver has the ability to lock on to 24 more satellites than using GPS alone.
