[3] OPERATING PROCEDURES
1. Turn ON the main power switch
.
2. Conrm that ready lamp
is illuminated.
NOTE: The ready lamp will not illuminate unless the incoming line voltage
is correct and within the x-ray’s operable range.
3. Select the appropriate tooth type (
), and conrm if the pre-selected
conditions (patient size
are suitable
for radiographing.
NOTE: To manually set the exposure time, depress either manual exposure
time adjust switch(
) until the desired exposure time
is displayed in exposure time display window
. While the unit is in
manual mode, other selection switches(
) do not affect
exposure time. (All the tooth selection lamps are off.)
To return to the automatic exposure time selection mode, depress any
one of tooth selection switches.
4. Depress the exposure switch
. When the exposure switch is depressed,
the exposure warning lamp
illuminates and the audible warning sounds.
Do not release the exposure switch until the audible warning and the
warning lamp terminate. Failure to keep the switch depressed will result
in the exposure being terminated prematurely.
5. To continue to radiograph other teeth, just select appropriate tooth
selection switch.
IMPORTANT : To protect x-ray tubehead from heat accumulation,
wait for 60 times of exposure time between exposures.
[Ex. 30 second wait interval for each 0.5 sec. exposure]
6. After use turn OFF the main power switch
in order to prevent accidental exposures.
NOTE : If the unit is left over 8 minutes without being operated and the
main power switch is kept on, gure 1 runs through the exposure time
display window. This does not mean that a malfunction of the unit has
occurred, but saves energy. The unit returns to normal condition by
pressing any one of the switches except the exposure switch.
