PRIORITY CHANNEL SCAN MODE:

This feature allows you to monitor two different channels at the same time.

While in the Priority Channel Scan mode you may hear transmission from either a primary or secondary channel when transmitting. The unit will always transmit on the primary channel unless the PTT button

VOX MODE:

The Voice Activated Transmission (VOX) function allows your voice to activate signal trans- mission automatically when the FR-1538 is used with an optional hands-free

microphone/headset (FRS-BHST). It also allows hand-free use when a microphone/headset is not being used without having to use the PTT button (14). When in the VOX mode, a short beep will sound after the termination of any VOX generated trans- mission.

VOX SENSITIVITY SELECTION:

This feature allows the user to select the voice/signal level at which the unit will transmit. The high sensitivity setting ( HI ) should be used in high background noise environments or when whispering. The low sensitivity setting ( LO ) should be used in low background noise environments. The normal (NR) setting can be used in most all typical applications.
