QUICK INSTALLAION
AH2401M, 24 in 1 CATV analog modulator, is designed for indoor 19'' rack. Make sure a space is left between modulators for air circulation. To prevent electric shock, never remove the ground pin. Insure that electrical input cables entering the building be connected to the building ground as close to the entry point as possible.
1.Feed in the Audio and Video connectors before turn on the power
2.Warm up the modulator and check the picture and audio
3.Set up the channels you want if the factory settings are not what you want
