Setting the date and time on NEC XN120 telephone systems

Applies to

This article applies to the following products.

Many telephone systems show the date and time on the display of system phones. This article explains how to set the date and time on NEC XN120 telephone systems.

Setting the time on NEC XN120 telephone systems can be done using an XN120 Vision phone. These are the NEC display phones that are supplied with the XN120.

The time on these systems should change automatically for daylight saving time (DST). Unfortunately, it is not enabled by default and most engineers do not bother to enable it. If it does not change automatically, contact us as we might be able to help.

Please note there is a battery inside the CCU (central control unit) that keeps the clock working when the power is off. As the XN120 is now many years old, the battery inside will most likely be low or flat. If the date and time are wrong after the power has been off, it is likely that this battery needs to be replaced. The correct battery is a CR2032, which is located inside the CCU.

If the date is correct, use the following steps as it is the simplest solution.
