OPERATION DESCRIPTION
ITEM OPERATON DESCRIPTION
Part I
1 Take out the camera, open the battery cover and insert SD card.
Camera cannot be powered on if insert the battery reversely. Insert
battery rightly and power on. Check if can power on normally.
Confirm if the FW version is correct during power on process. Enter
capture mode and confirm if the battery icon is consistent with the real
battery situation and if the memory icon on LCD is SD icon.
2 Knock the camera on the desk slightly for three times (5cm distance
between camera and the surface of desk, bottom down, do not scratch
the cosmetic). Camera cannot come out any abnormity, for example,
power breaks, SD card ejects, and etc.
3 Take a photo in Auto mode and press Rec-play button to
confirm the image. No abnormity can come out in the process of
photography, storage and play. Power off; remove the batter
y
and close
battery cover.
Part II
A 1. Insert the 3.0 VAC adapter, power on in theAuto mode. View
towards far and near in capture mode respectively, and check if the
images on LCD are clear and display is normal. Check LCD noise
facing to dark place, and if the bad dot accord to the standard.
2. Rotate the dial for each mode, check if each mode on LCD’s top left
corner displays normally. Press Display button (OK button) twice to
confirm if TFT-LCD operation is normal.
B 1.Press W/T to stretch out to Tele, and then draw back to Wide
segment, confirm if there is any abnormity of lens when stretch out and
draw back.
2. When view towards near (about 1.0m) or far (over 2.5m) in Wide
segment, press S1 to focus, and check if the focus is ok, which means
focus frame displays green. Stretch out to T segment and repeat the
focus action. That the focus frame displays red is NG. Take out and
maintain.
3. Press the arrow button (Self-timer mode ), TFT-LCD displays
self-timer symbol and self-timer’s time. Take a photo to the flower with
2s’forced flash.
C Make the spot test of 10 PCS from each section, trigger to take 30
pictures in forced flash mode and confirm if there is any abnormity,
such as missing flash, hang on, power off automatically etc.

D Shift to landscape mode and take a piece of photo towards
beyond (more than 3m) in No flash mode. Then switch to night
and red-eye mode , take a photo facing to the dark place
under desk, and the camera must have flash and the pre-flash and
main flash shall have clear differences before and after.
E Shifting to video mode , the symbol is displayed. Press Shutter
button to record more than 5s, using the sound box to catch record.
F Connect TV and press playback button to enter into playback mode,
view the pictures. There should not be NG pictures and the pictures
should not have color aberration. Select the Movie document, press
SET button to enter into movie play mode; The voice should not be
abnormal or too low. Press Wide button and LCD displays
nine-thumbnail image; press direction button can select picture up,
down, left and right.All the above operation should e normal. Take out
the abnormal ones to maintain and pull out the TV wire.
G Draw out 10 PCS from each section, shift to SETUP mode , select
LCD BRIGHTNESS and press OK button to enter LCD brightness
adjustment menu. Press left-right button to adjust LCD brightness to
confirm if the LCD brightness changes regularly.
H Select format menu to format the internal memory of camera. After
this, set to default to the camera. After all the above are ok, power off
and confirm if the lens can retract.

4. Firmware Update Procedure
To update this camera firmware, you will need to have
1. The new firmware file.
2. One SD card.
3. One card reader.
Please follow the steps below to perform the update process:
1. Prepare a formatted and empty SD card.
2. Insert a SD card to the card reader. Copy the firmware file (file name
should be "dc4345pr.bin ") into the SD card. Make sure the new firmware
file is copied to the SD card.
3. Insert the SD card into the camera.
4. Plug in the AC adapter into the camera.
5. Press "Shutter" & "Playback" button at the same time and press “Power”
button, then loosen “Power” button, LCD will display the image and loose the
“Shutter”, “Playback “ button. At this time camera enters update process
automatically and LED blinks.
6. When LED stops blinking, LCD will display the “OK” ,it means update ok.
