We combine the value packed MP4-120 Message Player featuring 4 channels that can be used for voice with or without tones, or musical tunes with our radio control package--eliminating the need for interconnecting control wires. The recordable channels are fully recordable and are stored in non-volatile re-programmable memory. Total time of recording is 8 minutes--2 minutes for each of the 4 channels.
