M-1
M-1
· Using ultra high frequency range, less interference and more reliable compare to traditional VHF. · Within 50MHz frequency range, with 250KHz channel separation, it can provide up t0 200 selections for channel,making it convenient to use with multiple machines at the same time, avoiding interference. · Auto matching frequency between transmitter and receiver. · Signal strength can be adjusted for longer range or shorter range to save battery.
