Power Supply

• Use only the special rechargeable lithium ion battery (NP-20) to power this camera. Use of any other type of battery is not
supported.

• The camera does not have a separate battery for the clock. The date and time settings of the camera are cleared about one day
after power is totally cut off (from both the battery and USB cradle). If this happens, be sure to reconfigure these settings after
power is restored.

LCD Panel

• The liq uid crystal panel of the monitor screen uses high-precision technology that provides a pixel yield in excess of 99 .99%.
This means that some pixels may not light or may remain lit at all times. This is due to the characteristics of the liquid crystal
panel, and does not indicate malfunction.

Lens

• Never apply too much force when cleaning the surface of the lens. Doing so can scratch the lens surface and cause malfunction.

• You may sometimes notice some distortion in certain types of images, such as a slight bend in lines that should be straight.
This is due to the characteristics of lens, and does not indicate malfunction of the camera.

Special AC Adaptor

• Power cord precautions for use in Singapore
The power cord set is not supplied. The power cord used must comply with relevant national and/or international standards.

RESETTING THE PLACE OF DESTINATION

When the main PCB is replaced, the setting of the destination will be changed, therefore resetting is required.
However, when the firmware is changed or fixed, the setting of the destination will be held, therefore resetting
is not required.
Use the destination setting script to change the destination flag as instructed below.

1. Have an SD card ready that have a corresponding script (autorun.scp) under the root directory.

2. Insert the SD card in the camera and turn on the power.
The script is located at Qv/soft/Adj_soft/exs770/Script in the service CD-ROM.

3. After a few seconds, one of the following messages will be shown in the screen.
The system will change the destination flag and turn off the camera automatically.

For Europe and UK

For Europe_UK

• Number of menu languages: 10 languages

• Movie filming time limited

Complete

4. Remove the SD card from the camera and turn on the power to confirm if the camera is set as you wish
including the number of the menu languages and the scene of the best shot mode.
If there is no problem, the setting is completed.
