2. Receives a response
Response = "NTCONTROL 1 1aa6c14e" + (CR)
"1aa6c14e" = 8 bytes random characters
3. Generates a hash value (message digest) from "admin1:panasonic:1aa6c14e" by using the MD5 algorithm.
"admin1" = Administrator authority user-name
"panasonic" = Password corresponding to "admin1"
Hash value = "01466bc27ed8c0b7e607471580c55953"
4. Transmits the command
Transmission data = "01466bc27ed8c0b7e607471580c5595300QPW" + (CR)
5. Receives a response.
Reception data = "00000" + (CR)
6. Disconnects the connection with the projector.

SECTION 1 SERVICE INFORMATION
5. Notes on service
5. 1. Before service operation
5. 1. 1. LCD panel
1. The display unit of this projector comprises three LCD panels. Although an LCD panel is a product of high-precision tech-
nology, some of the pixels on the image may be missing or constantly lit. Please note that this is not a failure.
2. Displaying a still image for a longer time may result in an after-image on the LCD panels. If this happens, display the all
white screen in the test pattern for an hour or more.
5. 1. 2. Lamp
1. The light source of the projector is a high-pressure mercury lamp.
2. A high-pressure mercury lamp has the following characteristics.
• The luminance of the lamp will decrease by duration of usage.
• The lamp may burst with a loud sound or have its service life shortened because of shock, chipping, or degradation due to
cumulative runtime.
• The lamp life varies greatly depending on individual differences and usage conditions. In particular, continuous use for 12
hours or more and frequent off/on switching of the power greatly deteriorate the lamp and affects the lamp life.
• In rare cases, the lamps burst shortly after projection starts.
• The risk of bursting increases when the lamp is used beyond its replacement cycle. Make sure to replace the lamp unit
regularly.
(Refer to items “When to replace the lamp unit”, “How to replace the lamp unit”)
• If the lamp bursts, gas contained inside of the lamp is released in the form of smoke.
• It is recommended that you store the Replacement Lamp Unit as a contingency
Replacement lamp unit : ET-LAV300
Note
* Panasonic takes no responsibility for any damage or malfunction of the
product resulting from use of lamp units which are not manufactured by
Panasonic. Use only specified lamp units.
Attention * Please be sure to read the warnings and notices on the lamp that is
described in the Operating Instructions. "Read this first!", "Precautions for
use", "Maintenance/replacement"
5. 1. 3. Air filter unit
1. Make sure that the air filter unit is properly attached before using the projector. If it is
not properly attached, the projector will suck in dirt and dust causing a malfunction.
2. The cleaning and replacement cycle of the air filter unit varies depending on the us-
age environment.
