commands, if the applicable monitor does not exist, no response will be
returned but only in this case, the command to cancel the target of the control
will not be accepted for following 90 seconds.

On PN-V601, 36-Multi (6 x 6), when turning ON the signal output device of
ASTRODESIGN that is specialized for the users who use the HDMI connection, in
very rare cases, the signal resolution would become 4095 x 16.

From January 2012 (Firmware V1.09)
When using DVI / HDMI the screen disappears for a moment and then reappears.
If the monitors were powered ON after 2~5 seconds delay when connected to
certain devices (Matrix switcher DXP 44 DVI PRO manufactured by Extron) and
PN-V601 with DVI Daisy chain and then inputting the content without HDCP, the
screens on the monitors (From the monitor-ID2) other than the monitor-ID1
connected with the Daisy chain would be frozen with the noise like a sandstorm
being displayed.

When connecting a PC (HP Z600/Z400 + Graphic Board NVIDIA Quadro FX 1800)
and 3 units of PN-E601
’s with HDMI and then starting up the PC, the image was
displayed in a reduced size.
When power ON under low temperature, the operation of the power supply PWB
became unstable. This caused the phenomenon that the backlights would not be lit
or a part of the areas would be dark. For the improvement of this phenomenon, the
default value of PWM FREQUENCY which is the setting of PWM frequency for
dimming the brightness has been changed from AUTO (Max 3KHz) to HIGH
(800Hz locked).

From February 2012 (Firmware V1.11)
When power ON under low temperature, the operation of the power supply PWB
became unstable. This caused the phenomenon that the backlights would not be lit
or a part of the areas would be dark. In the case that all power supply PWBs are
the ones that the measures have been taken, the maximum frequency when the
setting is AUTO will be set to 3KHz and in the cases other than above the
maximum frequency will be set to 800Hz.

From March 2013 (Firmware V1.15)
When a particular PN-V601 and PN-ZB02 (Interface extension board) are
combined, it takes about 2 minutes to turn on backlight after power on. Then a
back light error occurs after turning on the backlight.

"BOTU" sound may have occurred when the power supply is turned OFF, the off-
sequence of voice amplifier was changed.
