INTRODUCTION
This Service Manual & Parts List describes procedures for inspecting and repairing the InfaLite. It also describes
troubleshooting in faulty conditions.
The procedures described in this Service Manual should be carried out only by personnel trained in electricity
and the operation of the unit. Neither Atom Medical Corporation nor its representative will be responsible for the
quality and performance of the unit if the unit should not be handled as instructed or if unauthorized parts should
be used in repairs. It should be noted that any responsibility arising from inspecting or repairing the settings of
the unit lies with the person who carried it out.
Read this Service Manual & Parts List carefully and familiarize yourself thoroughly with its contents before
inspecting or repairing the unit. Keep this Manual where it is readily accessible for reference when needed. For
more detailed information on inspecting and repairing the unit, contact your local Atom representative. Read the
Operation Manual thoroughly before using the Service Manual.
SAFETY INFORMATION
Please read the Service Manual carefully before operating the unit. Please follow the instructions when operating
the unit.
Basic Instructions
1. Medical institutions are responsible for the maintenance, inspection and care of the unit.
2. When you choose to have the unit maintained and inspected or when the unit is found to be in need of
repairs from the results of inspection, consult your local Atom representative and take one of the following
measures.
(1) Ask someone who has completed a training course specified by Atom and who has sufficient technical
knowledge and skills to do the work.
(2) Ask Atom to send its service engineer if a person who has completed a training course specified by Atom
and who has sufficient technical knowledge and skills is not available.
(3) Ask Atom for its approval of returning the unit for repair service.
3. Follow the instructions for safety. Follow the operating precautions described in this Service Manual and the
Operation Manual for the safe use of the unit.
4. Inspect the unit on a periodical basis. Periodical inspection is needed to use the unit under optimum conditions.
5. Take proper measures to ensure that a defective unit will not be used by mistake before it is properly inspected
and repaired for normal operation. Such measures include indicating on the unit that it is under inspection
or repair and keeping it away from other devices that function correctly.

Precautions on Jamming
WARNING
Electric surgical knives, portable and mobile communication equipment, and other devices which
generate high-frequency noise can cause jamming to various kinds of electric equipment for medical use and thus result in malfunction.
Since portable and mobile communication equipment, etc. are often used in medical facilities, some
measures should be taken to prevent jamming due to such devices.
Portable and mobile communication equipment and other devices which generate high frequency
should not be used near the unit during its operation to prevent malfunction of the unit due to jamming.

Do not disassemble or modify the unit.
Otherwise, a fire, an electric shock or injury may result.
In Case of Trouble
CAUTION
If any abnormal condition or trouble should occur to the unit, indicate on the unit that it is out of
order and contact your local Atom representative or service engineer immediately. See the end of
this Service Manual for whom to contact.

Measuring the Light Intensity
Check that the light intensity is operating at its default level every six months.
Use a calibrated commercial light intensity measurement device to measure the light intensity.
(1)
Attach the mattress cover to the mattress, then place
the light intensity measurement device on the mattress cover. Set the irradiation head lens cover and
the light detector so that they are parallel, then align
the lens cover and the light detecting section of the
light detector so their centers are aligned and they
are 60cm apart.
CAUTION
● Use a clean mattress so that correct measurements can be obtained.

Is the lens cover dirty?
If you are using an incubator, are the main unit’s irradiation head
and hood vertical?
The light does not turn on.
✽See “4-1. Operating the Irradiation Head” of the Operation manual.
Is the non-contact sensor responding to something black?
Is the operation indicator “green”?
✽If the operation indicator does not turn on or turns on in a color
other than green, the non-contact sensor has stopped working or
is broken. Contact your local Atom representative.
