• Reset the units by disconnecting them from the electrical power and use a pin to press the reset key until you either hear a beep, or the monitor turns off. Wait about 15 minutes before plugging the units back in. Allow up to one minute for the camera and the parent unit to synchronize.

• Is the unit turned on? Press and hold the ON/OFF button on the Parent Unit to turn it ON.

• Is the correct camera selected? Change the camera number, if necessary.

• Is the video display turned on? Press the VIDEO ON/OFF button to turn it on.

• When operating using batteries only, the Display will go blank after 5 minutes or 30 minutes or 60 minutes to save power (depending on video settings). The unit is still active and will give you audio alerts. You can reactivate the screen by pressing any button.
