Installation and Preparation
1. Press the [MENU] button.
• Opens the menus in accordance with the instructions
provided in MENU Screen Operations (page 17) in the
sequence of [MENU]
→ [OPERATION MENU] →
[CLOCK SET].
* The time cannot be set when the VR-509 is recording,
during DVD exporting, or when operating in the timer
mode.
* Additionally, the time cannot be set when synchronization
with the web browser NTP server has been activated.
(See page 78)
* Take care when changing the date and time settings if
recording data is stored on the hard disk. If the dates and
times are duplicated or set earlier, there is a chance that
the playback, skip, jump, search and other operations will
not be performed normally.
2. Select your desired item with [ W/X], and then press
[–/+] to change the value settings.
• Set the current date and time in “D”, “M”, “Y”, “H” and
“M”.
3. Press the [SET] button.
• The confirmation screen will be displayed.
4. Select [SAVE] and press the [SET] button.
• The date and time will now be set. The clock will start
operating at the set time with the second value at 00.
„ The “seconds” display is adjusted by pressing [PLAY
STOP] while pressing down on [FUNCTION]. However, this
will not be reset during recording.
• When the “seconds” value is 29 or less, the “minutes”
value remains unchanged, and the “seconds” value is
reset to 00.
• When the “seconds” value is 30 or more, the “minutes”
value is increased by one, and the “seconds” value is
reset to 00.
„ Clock Reset signal input terminal
The recorder’s clock will be reset when the relevant signal
is input. The method of resetting the clock is the same as
explained above in “Adjusting the seconds display with
button operations.”
• It is possible to align the time with the master clock and
the clocks on other equipment by receiving signals.
„ Clock Reset signal output terminal
The clock reset signal is output in accordance with the
following timing:
• When the recorder’s internal clock reaches 00:00 and 12:00.
• It is possible to align the clock with two or more VR-509
units in calibrations of seconds.
It is possible to adjust the clock by connecting to the NTP
server. See the section on “Adjusting the Clock with the NTP
Server” on page 78 for more details.
* The internal clock is accurate to within about 60 seconds per
month. (If used in a 25°C environment)
For greater accuracy, access the NTP server.
* See “Using the NTP Server Function” on page 107.
* It is recommended that the clock is adjusted to the correct
time once per month to obtain accurate times.

When the [CLOCK RESET OUT/IN] terminal is connected,
the time for two or more VR-509 units will be synchronized
twice a day at 12:00 noon and midnight.
MEMO
• Make sure the power supply to the relevant units has
been switched off before establishing the connection.
• When the clock reset output terminal is to be
connected in an array with multiple units, make sure all
units are of the same type. Malfunctions will occur if the
voltages on the input devices are not aligned. Also,
note that there are cases where the clock will be reset
for all other input units if the power supply to one of
them is switched off.
CAUTION
When aligning the clock during recording with the clock
reset input or with the NTP server, there is a chance that the
recording time will be duplicated if the clock has advanced
past the actual time.
The search and audio playback functions will not operate
normally in this event.
CAUTION
