3. Press the hand pump slightly so that the indicated pressure value becomes to “-5.0”.
Few seconds later, decrease the pressure slightly. Therefore adjust the indicated pressure by pressing the hand pump.
Note:
Perform the pressure adjustment by hand pump pushing amount.
If the pressure becomes too high, perform the adjustment again after removing the vacuum pad.
4 The change value is getting settle, wait 120 seconds with keeping the pressure at around the -5.0kPa (within -0.0kPa to -10.0kPa).
Caution:
Do not operate the hand pump after settling the change value.
If operate the hand pump again, wait 120 seconds form then.
5. Write the indicated value, leave for 2 minutes, and check the pressure changes value is satisfied the following value by comparing between written
indicated value and indicated value.

0.45 kPa or less: OK
0.46 kPa or more: NG
Caution:
Do not open the connector cover for two minutes after the leak test.

1-4-3. In The Case of Inspection Result NG
Perform by following procedure
1. Confirm that there are not any dust on the USB door rubber and USB door plate.
↓
Confirm that there is not any dust on the vacuum pad.
↓
Cover the microphone hole so as not to damage the Microphone Sheet.
(Cover the microphone hole surely. (e.g. with using Microphone Sealing Rubber (4-429-171-01))
↓
Expand the suction time for 60 seconds, and perform the measurement again.
2. Check the cabinet condition, and then perform the measurement again.
3. If there is no improvement symptom, replace the front cover sub assy and rear cover (+LCD) assy, and perform the measurement again.
1-5. PERIODIC MAINTENANCE
1-5-1. Periodic Maintenance
Opening/closing the USB door may lead to degradation of the sealing gasket. We recommend that once a year you take the camera to your dealer,

If there is the request for check, perform the procedure below.
Checking Items
• Confirm that there is no air-leak.
• Confirm that there is no strain on the exterior.
• Confirm that there is not any dust on the USB door.
• Replace the USB door rubber.
1-5-2. Replacing the USB Door Rubber
1. Remove the three fixed screws of USB door rubber.
