Pushing right side of this switch energizes the x-ray unit.
(Ready lamp and pre-selected lamps for patient size, cone type and film speed
illuminate.)
It is recommended to keep this switch OFF when the unit is not in use in
order to prevent an accidental exposure.

ww

w Ready Lamp

ww

This lamp lights when the line voltage is within operable range.
When this lamp is not on, exposure can not be made.

a) Film speed : Refer to page 1, Layout of control box.

Three kinds of film speeds are factoty set (a,b,&c) and can be selected by
the film speed selection switch, Item 10 on page 1.

a = Film speed No. F.09 (equivalent to ISO speed group "D", or Kodak Ultra-Speed film)
b = Film speed No. F.04 (equivalent to ISO speed group "F/E", or Kodak InSight film)
c = Film speed No. F.02 (equivalent to ISO speed group "F")

b) Three film speeds can be selected. Pushing this switch momentarily indicates

the film speed number being selected in exposure time display window (
Depressing the switch for more than 2 seconds alters the film type being selected.

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 0.5 sec. exposures]

6. After use turn OFF the main power switch

qq

q in order to prevent accidental

qq

exposures.

NOTE : If the unit is left over 8 minutes without being operated and the

main power switch is kept on, figure 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.

MAINTENANCE

Model 096 BELRAY X-ray unit requires the following post installation confirmation and
periodic maintenance checks to be performed by dealer service personnel, to ensure that the
x-ray unit is functioning within the manufacturer’s specifications and remains in compli­ance with the Standard.
It is the responsibility of the owner of the unit to see that these maintenance checks are done
once every 6 months and that they are performed by a trained, certified service technician.

The specific instructions to perform these checks are located within the Model 096 installa­tion manual.

A. Line voltage confirmation
B. Tube current confirmation
C. Inspection of arm and head movements
D. MECHANICAL SAFETY

1. The wall plate should be checked to confirm its secure
attachment to the wall.

2. The arm mounting bracket should be checked to con­firm its secure attachment to the wall mounting plate.
The arm mounting bracket must be level horizontally
and vertically.

3. Check to insure the horizontal arm is not raising up
and out of the arm mounting bracket. This should be
observed routinely by treatment room personnel.
