A remotely controlled device for making videotape recording reservations on a videocassette recorder using a remote pushbutton telephone to enter recording reservation codes such as PlusCodes, constructed so that the audio portion of the TV program currently being recorded can be monitored by the user via the telephone whenever the user calls up the device. Prior to the inputting of the recording reservation codes, the user may turn off the transmission of the audio portion of the TV program by transmitting a specific code in order to ensure that the audio portion of the TV program does not mask the sound of DTMF tones during inputting of reservation codes.
