If your Door Viewer is unresponsive, please check the following:

• Ensure that the batteries are inserted the correct way, following the polarity in the diagram below.
• Try changing the batteries for a fresh set of quality alkaline batteries.

In this case, please follow the process below to troubleshoot:

• Carefully remove the viewer from the mount. Be careful when pulling it away, as the cable will be connected.
• Firstly, inspect the cable that runs from the camera and into the viewer. Ensure that it has not be pinched, trapped or damaged.
• Next, ensure the cable connector is securely plugged into the viewer.

Once these checks have been done and you have fitted the viewer back in place, please try the viewer again.

The Yale Digital Door Viewer Memory Plus 4500 is powered by 4 AAA batteries and designed for energy efficiency. Thanks to its automatic shut-off feature after 10 seconds of use, the device can typically last between 2 to 6 months, depending on how frequently it's used. If you are experiencing signficantly less than this, please check the points below.

• Avoid using rechargable batteries as these typically deliver a lower voltage (1.2V vs. 1.5V for alkaline), which will impact device performance and battery life. Additionally, they can be sensitive to cold temperatures, so if your device is installed in an unheated space like a shed or garage, winter conditions might affect reliability.
• Damage to the cable which runs from the camera and into the viewer could also impact battery life. Inspect this to ensure that it has not be pinched, trapped or damaged.
