Internet Radio needs time to warm up …
• Typically a few seconds are required for selected Internet radio
station to start playing:
1.Access to the station
2.Buffering of streaming data (to a level) so that incoming
music (data) stream can be played continuously, depending
on
– Speed of the internet connection is at the time
– Heavy congestion on the internet or at the music server will take
even longer time for the music to start playing
• Buffering indication to display on the screen upon connecting to
station to provide indication that streaming and buffering is
happening.

Wi-Fi Network – Safety and Privacy
• When my neighbor has a network as well
– (Wi-Fi) Network access is identified by SSID (and maybe with security
such as WEP/WPA/WPA2 key)
– WACS would not access your neighbor network unless you set up your
system to connect to it
– Your neighbor cannot easily access your WACS if you have your Wi-Fi
protected with WEP/WPA/WPA2 unless your security is comprised
• WEP/WPA/WPA2 safety
– WPA and WPA2 are more secure than WEP provided a strong
password or pass-phrase is used

Wi-Fi Network – Interference and Range
• Possible sources of interference
– Microwave, DECT phone, Bluetooth device, and another Wi-Fi network
close by on the same channel, thick walls
• Mitigate interference
–Use Wi-Fi router
– Change to different channels, channels 1, 6, and 11 are recommended
•Switch Wi-Fi channels
– Change the operating channel of the device via WADM / Web page
• Good/bad for range
– Wi-Fi networks have limited range. A typical Wi-Fi home router using
802.11b or 802.11g with a stock antenna might have a range of 45 m
(150 ft) indoors and 90 m (300 ft) outdoors

Booting procedure WAC700
Consumer Service, September 2008, Reference
As illustrated in figure 1, WAC700 (Center) consists of two major parts: Front Board and
Module Board. There is one processor/MCU (Front Processor) in Front Board and two
processors/MCUs on the Module Board.
The Front Board is the master in the system. It controls the power of Module Board and it
communicates with Module board via I2C bus.
When power up, the processor/MCU in Front Board runs program from its flash memory and
shows messages on LCD (e.g. “PHILIPS”“Booting up, pls wait”). Mean while it will enable the
power for Module board to let the 2 processors/MCUs to run their program from
flash/SDRAM/HDD. The MCU in Front Board will keep showing “Booting up, pls wait” until the
processor in Module Board gives ready signal via I2C bus. If there is no response from Module
Board in certain period (e.g. 1min), Front Board will recycle the power of Module Board to
recover.
The processor 2 on Module Board starts to run program form its flash memory after the
power is enabled by Front Board. Then it copy more program from HDD to SDRAM for
running. Meanwhile it transfer the program to the processor 1of Module Board for running.
Once Processor 1 gets the program image, it copies to its SDRAM to run and send ready signal

12NC 310330855641. When the user trying to recover the locked
CD using excess force, the CD clamper is damaged.
Update the software of the device to v1.2.10 may prevent the CD locking
inside the slot loader, thus prevent user from using excessive force to
recover the disc.
