NEC DSX and DS Phones: Change the Time and Date

Note: The system time and date on NEC DSX and DS systems must be changed from extension 300. The instructions are the same for both systems; the only difference is that the Speaker button on DS phones is labeled SPK.

• Without lifting the handset, dial #TD from extension 300. Do not press any other keys first.
• Enter the time in 24-hour format: two digits for the hour, two digits for the minutes, and two digits for the seconds.
• Press HOLD.
• Enter the date in this format: two digits for the month, two digits for the day, and four digits for the year.
• Press HOLD again, then press SPEAKER (or SPK) to save the settings and exit.
