SYSTEM DESCRIPTION
The CRC®-712MH Radioisotope Dose Calibrator consists of the following:
•Readout Unit
•Chamber(s)
•Power Cord
•Printer (optional)
ELECTROMAGNETIC INTERFERENCE POTENTIAL
This equipment generates radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to nearby devices.
However, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference, the user is encouraged to try to correct the
interference by one of the following measures:
•Increase the separation between the equipment and the affected device.
•Plug the unit into an outlet on a circuit different from that to which the affected device
is connected.
If this fails to correct the problem, please contact Capintec’s Authorized Service Center.

IMPORTANT SAFETY INFORMATION
The CRC®-712MH measurement system has been carefully designed to give you years of
safe and reliable performance. As with all electrical equipment, however, there are basic
precautions you must observe to avoid injuring yourself, the patient or damaging the
equipment.
•Follow the unpacking and assembly instructions document, and read this manual
carefully before using this equipment. Be sure to save all provided documents for
future reference.
•Understand all warning and caution labels as explained in CHAPTER 1: SAFETY
before operating this equipment.

CHAPTER 1
SAFETY
These warnings and instructions for use form an integral part of the CRC®-712MH and must
therefore be kept available for consultation at all times. Precise compliance with the
instructions is an essential condition for normal use, correct application and thus safety of the
user.
SYMBOL DEFINITIONS
“ON” (power)
“OFF” (power)
WARNING AND CAUTION LABELS
Located on the back of the Readout Unit is a label, (Figure 1-1), providing the system power
requirements, and the replacement fuse values for power line voltages.
Please reference CHAPTER 7: CLEANING AND MAINTENANCE for instructions on how to
change the fuses and line voltage of the CRC®-712MH.
A fire hazard may exist if the wrong size of fuse is installed.
Figure 1-1
Located on the Power Cord is a label, (Figure 1-2), indicating that the grounding reliability
can only be achieved when the equipment is connected to an equivalent receptacle marked
hospital only or hospital grade..
January 08 SAFETY 1 - 1

CAPINTEC, INC. CRC®-712MH
Figure 1-2
Located on the chamber are 2 labels.
The first label (Figure 1-3) contains statements denoting not to remove the cover because
there are no adjustments that the user can perform in the chamber.
Figure 1-3
The second label (Figure 1-4) is located in three places (on the bottom of the chamber, on
the 150 Volt Battery pack inside the chamber & on the cover of the main power supply in the
readout unit) and pertains to the electrical safety of the chamber and readout. It is necessary
because of the high voltage present (approximately 150 volts) on the Battery board installed
in the chamber and the line voltage inside of the readout. A screwdriver is necessary to
remove the covers to both the chamber and the readout.

CAUTIONS AND NOTES CAUTION
Only qualified/trained personnel should operate this unit.
CAUTION
If the equipment is used in a manner not specified in this manual, the protection provided by
the equipment may be impaired.
CAUTION
No internal adjustments inside the chamber or readout that may be performed by the user
within the conditions of the warranty. Due to the presence of high voltages, opening the
cover with the system plugged in may be hazardous. Refer all servicing to qualified
personnel.
CAUTION
Never use the calibrator without the well liner in place. Liners are inexpensive and easy to
replace. A contaminated chamber is a very costly mistake. If the unit becomes contaminated
remove the liner and clean the unit as stated in CHAPTER 7: CLEANING AND
MAINTENANCE before operating.
CAUTION
Care must be exercised when moving the instrument or when maintenance is performed.
The shielded cylinder is heavy (13.6 kg or 30 lb). In order to provide the required sensitivity,
the wall of the ionization chamber is extremely thin and the chamber is filled with pressurized
gas. It is therefore, essential to avoid mechanical shock or vibration of any kind.
CAUTION
When working with a heavy sample (especially a CapMac or Moly Assay Canister) always
lower it gently into the chamber well. Dropping any heavy object into the well can cause
permanent, expensive damage.
CAUTION
It is desirable to leave the unit powered at all times in order to prevent moisture absorption
and to maintain the stability of the instrument (especially if the instrument is subjected to high
humidity or low temperature).
CAUTION
The sensitivity of the chamber is somewhat dependent upon the vertical position of the
sample within the well. All calibrations were done with a Standard Sample placed in the
supplied sample holder (dipper). It should be noted that in this configuration, the sample is
not quite at the bottom of the well. If, for any reason, you make a measurement without using
the dipper, be sure that the sample is in the correct vertical position. Both the CapMac and
the Standard Moly Assay Canister maintain the same position as the dipper.

CAPINTEC, INC. CRC®-712MH
CAUTION
Use of accessories not listed in this manual, may compromise the compliance of this product
to IEC 60601-1. Therefore, only recognized accessories shall be used at all times. Also the
Electromagnetic Interference (EMI) may be compromised which may affect other devices
located in the same area as the CRC®-712MH or the CRC®-712MH may become susceptible
to EMI.
CAUTION
The unit contains lead. Appropriate caution should be taken if the interior of the unit is
exposed. The unit should be disposed of in accordance with local and national regulations.
CAUTION
The unit contains a Lithium Battery. This should be disposed of in accordance with local and
national regulations.
CAUTION
The user should always verify the validity of any measurement or test result in order to
minimize measurement errors.
NOTE
It is recommended that periodic re-calibration of the unit be performed by Capintec’s
Authorized Service Center to guarantee that the instrument's high reliability is maintained.
GENERAL SAFETY TIPS
•Unplug the equipment before cleaning it. Use only a damp cloth; do not use solvents
or aerosol cleaners.
•To protect the equipment from overheating, do not use the equipment directly in front
of a radiator or heat register.
•Do not use the equipment near water, or spill liquids of any kind into the equipment.
•Be sure that your power source matches the rating listed on the CRC®-712MH
calibrator.
•The CRC®-712MH power cord has a grounded, 3-prong plug as a safety feature, and
it will only fit into a grounded outlet. Do not use an adapter to defeat the grounding.
•To avoid damaging the power cord, do not place anything on it or place it where it will
be stepped on. If the cord becomes damaged, replace it immediately.
•Aside from the routine maintenance described in this manual, do not try to service
this equipment yourself. Do not make any adjustments other than those outlined in
this manual, as you may in-validate the calibration or cause damage requiring
extensive repair work. Refer servicing to qualified service personnel.
