INTRODUCTION
This manual contains the necessary instructions for proper operation, installation,
adjustments and calibration of the APX 525 & 625 High Frequency Generator.
All persons operating or servicing this equipment need to have read this manual
beforehand. You must have a thorough understanding of the APX 525 or 625 and its
proper use before you make any radiographic exposures.
Damage in Transportation
All packages should be closely examined at time of delivery. If damage is apparent,
have notation of "Bad Order" placed by the delivery driver on all copies of the freight
or express bill. If damage is of a concealed nature, notify the transportation agent as
soon as possible to make an "Inspection report of damage" but in any event not later
than 15 days after delivery. A transportation company usually will not pay a claim for
concealed damage if an inspection is not requested within this 15 day period. The
company's responsibility ceases when the transportation company accepts the
shipment in good order, and the company assumes no liability for loss or damage
after delivery to the carrier.

X-Ray Protection
X-ray equipment may cause injury if used improperly. The instructions contained in
this manual must be read and followed when operating the APX 525 or 625 High
Frequency Generator. Del Medical Imaging Corporation's authorized dealers will be
glad to assist in placing the APX 525 or 625 into operation.
The APX 525 and 625 provides a high degree of protection from unnecessary
radiation. However, no practical design can provide complete protection nor prevent
operators from exposing themselves or others to unnecessary radiation.
