the same process as above to store a new tube voltage adjustment value for 70 kV.
③
When the change of tube voltage adjustment value is completed, the standard digital value for tube voltage
is automatically changed in conjunction with the adjustment value stored.
3.4 Setting the alarm
(1) To enter this mode
Hold down the T1 and T2 buttons for approximately three seconds.
(2) The status when you enter the mode
①
The ready light blinks. The lights for teeth, patient, cone, tube voltage, tube current, exposure, film, and
digital mode are off.
②
The seven-segment LED displays “bu.X”. X represents the alarm status number held at the time.
(3)Operation and display
①
Press the
△
or
▽
button to increase/decrease the alarm status number displayed on the seven-segment
LED. Select the value you want and press the patient selection button for approximately one second. An
alarm sounds and the value is stored as a new alarm status number. “bu” represents buzzer and the
following numbers have the meanings as described below:
0: A standard alarm may sound only during exposure, when an error occurs, when changing film
type/digital mode, when changing cone type, and in the setting mode.
1: A short alarm sounds when any of the
△▽
, teeth, patient, cone, tube voltage, tube current,
exposure, film, and digital buttons are pressed (small sound volume: DUTY 10%). The sound
volume of exposure decreases.
2: A short alarm sounds when any of the
△▽
, teeth, patient, cone, tube voltage, tube current,
exposure, film, and digital buttons are pressed (standard sound volume: DUTY 50%).
②
Select the value you want and press the patient selection button for approximately one second. An alarm
sounds and the value is stored as a new alarm setting value. Factory default is “bu.2”.
3.5 Manual setting of preheating power
(1) To enter this mode
Hold down the Film and T4 buttons for approximately three seconds.
(2) The status when you enter the mode
①
The ready light blinks. The lights for teeth, patient, cone, exposure, film, and digital mode are off.
②
For the tube voltage light, 60 kV is on.
③
The seven-segment LED displays “h.XX”. XX represents the preheating setting value for 60 kV/4 mA
held at the time (00 to 1F). The standard setting is “h.10”.
(3) Operation and display
①
Press the
△
or
▽
button to increase/decrease the preheating power setting value displayed on the
seven-segment LED. Select the value you want and press the patient selection button for approximately
one second. An alarm sounds and the value is stored as a new preheating power setting value for 60 kV/4
mA.
②
Pressing the tube voltage selection button switches the tube voltage light to 70 kV and the tube current
selection button to 7 mA. Follow the same process as above, and the preheating power setting value for
60kV/7mA, 70kV/4mA and 70kV/7mA can be stored.
3.6 Automatic adjustment of preheating power
(1) To enter the mode
Hold down the T1, T4, and T5 buttons for approximately three seconds.
(2) The status when you enter the mode
①
The ready light is on. The lights for teeth, patient, cone, exposure, film, and digital mode are off.
②
For the tube voltage light, 60 kV is on. For the tube current light, 4 mA blinks for approximately three
seconds and then comes on.
③
”h.XX” blinks on the seven-segment LED simultaneously with the
②
and then “0.01” is displayed.
(3) Operation and display
①
Press the exposure switch to make an x-radiation for 0.01 seconds. If the tube current at initial rise falls
