Leader LV5300A - Mechanical Shock; Electrostatic Damage; Warming up; About Standby Mode

1.2.2 Mechanical Shock
This instrument contains sensitive components, so it may be damaged if it is dropped or
otherwise exposed to a strong shock.
1.2.3 Electrostatic Damage
Electronic components can be damaged by static discharge. Static electricity can build up in
the core wire of a coaxial cable. Before connecting a coaxial cable to an I/O connector of the
instrument, short the core wire of the cable with the external conductor.
1.2.4 Warming Up
To ensure more accurate measurements, turn ON the instrument approximately 30 minutes
before you intend to use it to allow its internal temperature to stabilize.
1.2.5 About Standby Mode
Even if you press the power switch to turn off this instrument, the instrument remains in
standby mode as long as the power cord is connected to the outlet. In standby mode, some
of the internal circuits operate and may generate heat. Unless necessary, keep the power
cord disconnected from the outlet.
1.2.6 Backup
This instrument has a last-memory feature. When you turn the power on, the instrument
starts with the panel settings that were in use the last time that it was turned off. If the
backup battery is out of power, the message "The last memory feature is disabled." will
appear, and this last-memory feature will no longer work.
To continually use the last-memory feature, we recommend that you replace the backup
battery with a new one every five years after you purchase the instrument. You cannot
replace the backup battery yourself. For details, contact your nearest LEADER agent.
1.2.7 About the LCD Panel (LV5300/LV5300A/LV5350)
There may be a small number of pixels in the LCD panel that do not light or are always on.
Note that this is not a malfunction.
The LCD panel supports a large number of video signals. SDI input signals are displayed
asynchronously on the LCD. Therefore, images may appear to flicker on the waveform and
picture displays.
In addition, the input SDI signal is temporarily stored in frame memory and is loaded by
using the LCD display synchronization signal—which is not synchronized with the input SDI
signal. Therefore, because frame skip—which skips over frames in the memory—and frame
repeat—which reads the same frames of the memory twice—occur, the image may appear
to flicker.
(An external sync signal can be used to synchronize the LCD to the input signal.)
