Vibration Function
When pre-programmed 2-tone, 5-Tone, MDC, and/or IDAS signals are received, the radio can vibrate with enough force to be felt through clothing.

Voice Recorder
Turn on and off the recording manually (with a button) and it will automatically record every incoming call and every transmission from that time forward for up to eight (8) minutes. The F52D series also allows users to program the radio to automatically record all RX and TX all the time, and old messages will delete when the memory is full. Push a pre-programmed button on the radio, allowing you to hear "the last message."

Safety Features
For emergency situations, the F52D series includes an emergency key and four emergency functions: man down, motion detection, stationary detection and lone worker. The motion/stationary sensor sensitivity level is programmable in 10 levels for each function.
