Hi. In the owner's manual for the CD192, there is no mention about putting the unit into standby mode. There is an explanation for the on/off switch, but the manual does not even mention putting it in standby, nor does it even acknowledge that there is a standby mode. In the section where the owner's manual explains all the remote control functions, the standby button is not mentioned, and it appears that it is grayed out like all the other buttons that pertain only to the DVD functions. Can anyone explain why? Are we supposed to put the unit into standby?
