Dustproof and waterproof
ET-538 can withstand long-term immersion under pressure, and put it into 1 meter deep water for a
long time. The time can be up to 1 hour without damaging the radio.
Long distance transmission
ET-538 adopts long antenna design, which effectively improves the transmission intensity and the signal effect is better
4 groups, 128 channels
4 groups, each group can add channels.
Built-in LED display
Built-in LED display, you can intuitively observe each set value (channel, volume, power).
Emergency button
The distant companion's radio receives the alarm sound from the distressed person, and the general
position of the distressed person can be roughly judged according to the sound strength for rescue.
