7. Modules containing electrical components are sensitive to electrostatic discharge (ESD). Follow
ESD safety procedures while handling these parts.
8. Some products contain more than one battery. Do not disassemble any battery, or expose it to high
temperatures such as throwing into fire, otherwise it may explode.
9. Refer to government requirements for battery recycling or disposal.
Compliance Statement
1. Caution:This Optical Storage Product contains a Laser device. Refer to the product specifications

Note：
1. Contrast Ratio (CR) is defined mathematically as:
2. Surface luminance is luminance value at point 5 across the LCD surface 50cm from the surface with all pixels displaying
white. From more information see FIG 2. LWH=Lon5 where Lon5 is the luminance with all pixels displaying white at center
5 location.
3. The variation in surface luminance, _WHITE is defined (center of Screen) as:
δHITE(9P)= Minimum(Lon1, Lon2,…,Lon9)/ Maximum(Lon1, Lon2,…Lon9)

12
4. Response time Tr is the average time required for display transition by switching the input signal for five luminance ratio
(0%,25%,50%,75%,100% brightness matrix) and is based on Fv=60Hz to optimize.
The response time is defined as the following figure and shall be measured by switching the input signal for “any level of grey
(bright) “and “any level of gray (dark)”.
Any level of gray (Bright) Any level of gray (Dark) Any level of gray (Bright)
FIG. 2 Luminance
5. Viewing angle is the angle at which the contrast ratio is greater than 10. The angles are determined for the horizontal or x
axis and the vertical or y axis with respect to the z axis which is normal to the LCD surface. For more information see
FIG3.

Scheduler
スケジューラー
1. User can set 7 schedulers to decide the power on/off
time, source, and frequency.
2. User can set any time, date, source, frequency in each
schedule
3. If user selects USB-photo or USB-music or
USB-movie in power on source, it will follow playlist to
play. If user didn't create playlist, system will depend on
USB-photo or USB-music or USB-move setting to auto
play the photo or music or move file in USB root.
4. Support power on source option : AV, Component,
HDMI1, HDMI2, DVD-D, VGA,USB-photo, USB-music,
USB-movie
5. schedule behavior
Case 1: if the power on time is same in different schedule,
system will use smaller schedule setting to power on.
Smaller schedule number priority is higher.
Case 2: if the off time of current Schedule is equal to the
power on time of next schedule, system will cancel
current off time and use next schedule off time.
Signal Check Priority
信号チェック優先度
1. User can set signal priority 1~5. (priority 1 is the
highest)
2. If current source signal is lost, start failover function
(auto search signal according signal priority setting). If
higher priority source exist signal, start failback function
(auto switch to higher priority source).

17
3. If user change source by input source OSD or
RS232/LAN command, source will keep at user selected
source(Don’t care Priority setting at this time until user
selected source signal is lost ). If user selected source
signal is lost, PID will search the active input source
according to the setting of Signal Priority Check. (even
user select source signal back, source will not change
back to user selected source).
4. After start signal check priority function, if higher priority
signal exist, auto switch to higher priority source. If all
source no signal, continue to search active input source
according to the setting of signal priority check.
5. In search signal of signal priority check setting, the
checking period is about 2 seconds each item. If user
change source manually, the check timeout is 10
seconds.
6. If user selects USB-photo or USB-music or USB-movie,
it will follow playlist to play. If user didn't create playlist,
system will depend on USB-photo or USB-music or
USB-move setting to auto play the photo or music or
move file in USB root.
7. In media, if user press EXIT key to leave playing mode,
the auto play behavior will stop.
8. Support source option : AV/Component, HDMI1,
HDMI2, DVD-D, VGA, USB-photo,USB-music,
USB-movie
(only can set one of USB-photo, USB-music and
USB-movie)
9. if signal priority check = enable, Power on source will
search the active source according the setting of
signal priority check. if signal priority check = disable,
power on source will the last source.
10 if signal priority check =enable and power on source is
USB, system will auto play USB function.
11. This function(Failover/Failback) is premised on
working automatically basically.
Usually, the source used by a primary is set as P1.It is a
backup function to when the signal of P1 is lost.
