NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflections from structures, object and people.
aField strengths from fixed transmitters, such as base stations for radio (cellular/cordless) tele-
phones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast can-
not be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed
RF transmitters, an electromagnetic site survey should be considered. If the measured field strength
in the location in which the CXDI-50G is used exceeds the applicable RF compliance level above,
the CXDI-50G should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the CXDI-50G.

Safety Information
Power Supply
WARNING
Be sure to turn OFF the power of each instrument before connecting or dis-
connecting the cables.
Also, do not handle them with wet hands. Otherwise, you may get an electric
shock that may result in death or serious injury.
WARNING Be sure to hold the plug or connector to disconnect the cable.
If you pull the cable, the core wire may be damaged, resulting in fire or electric
shock.
WARNING
Do not cut or process the cables. Also, do not place anything heavy, including
the instrument on it, step on it, pull it, bend it, or bundle it.
Otherwise, the cable may be damaged, which may result in fire or electric
shock.
WARNING Do not turn ON the system power when condensation is formed on the instru-
ment. Otherwise, it may result in fire or electric shock.
CAUTION Because the instrument’s cable is long, take care so cables do not get tangled
during use. Also, be careful not to get your feet caught in the cable.
Handling
WARNING
Always be sure to keep checking the condition of the system and the patient
to ensure they are normal during the use of the instrument.
If any problem is found, take appropriate measures, such as stopping the
operation of the instrument, as required.
WARNING
Never disassemble or modify the product as it may result in fire or electric
shock. Also, since the instrument incorporates parts that may cause electric
shocks and other hazardous parts, touching them may cause death or serious
injury.
WARNING Do not hit or drop the instrument. The instrument may be damaged if it
receives a strong jolt, which may result in fire or electric shock if the instru-
ment is used without it being repaired.
WARNING
Wipe the CFRP plate of the sensor unit with ethanol or glutaraldehyde solu-
tion to disinfect it each time a different patient uses the instrument, in order to
prevent infection.
If the optional grid unit is being used, disinfect its surface.
Please consult a specialist for the procedure for disinfection.
CAUTION
Do not spill liquid or chemicals onto the instrument or, in cases where the
patient is injured, allow it to become wet with blood or other body fluids, as
doing so may result in fire or electric shock.
In such situation, protect the instrument with disposable covering as neces-
sary.
CAUTION Turn off the power of each instrument for safety when they are not going to be
used.

When Problem Occurs
WARNING
Should any of the following occur, immediately turn OFF the power of each
instrument, unplug the power cable from the AC outlet, and contact Canon
representative or distributor.
- When there is smoke, odd smell or abnormal sound.
- When liquid has been spilled into the instrument or a metal object has
entered through an opening.
- When the instrument has been dropped and it is damaged.
Maintenance and Inspection
WARNING For safety reasons, be sure to turn OFF the power of each instrument when
the inspections indicated in this manual are going to be performed.
Otherwise, it may result in electric shock.
WARNING
When the instrument is going to be cleaned, be sure to turn OFF the power of
each instrument, and unplug the power cable from the AC outlet.
Never use benzine, thinner or any other flammable cleaning agents.
Otherwise, fire or electric shock may result.
WARNING
Clean the plug of the power cable periodically by unplugging it from the AC
outlet and removing dust or dirt from the plug, its periphery and AC outlet with
a dry cloth. If the cable is kept plugged in for a long time in a dusty, humid or
sooty place, dust around the plug will attract moisture, and this could cause
insulation failure which could result in a fire.
WARNING The instrument must be repaired by a qualified engineer only.
If it is not repaired properly, it may cause fire, electric shock, or accident.
CAUTION For safety reasons, be sure to inspect the instrument before using it.

1. Overview
The Canon Digital Radiography CXDI-50G is a portable X-ray digital camera that can
take images of any part of the body.
It directly converts the X-ray images captured by the LANMIT (Large Area New MIS
Sensor and TFT) sensor into a high-resolution digital images.

2. Notes for Using the Instrument
Handling
Handle the instrument carefully, as it may
be damaged if something is hit against it,
dropped, or receives a strong jolt.
Also, handle the optional grid unit with
care too.
Do not pull the cable. Also, do not pull the
sensor unit when the cable is tangled with
something. Otherwise, the cable may be
damaged, which may result in fire or elec-
tric shock.
Before Exposure
Sudden heating of the room in cold areas will cause condensation to form on the instru-
ment. In this case, wait until condensation disappears before performing exposure.
If the instrument is used with condensation formed on it, problems may occur in the qual-
ity of the instrument.
When an air-conditioner is going to be used, be sure to raise/lower the temperature gradu-
ally so that a difference in temperature in the room and in the instrument does not occur, to
prevent forming of condensation.

2. Notes for Using the Instrument
– 3 –
During Exposure
Do not apply excessive weight to the sensor unit. Otherwise, the sensor may be damaged.
Limit of Load
Uniform load: 150 kg over the whole area
of sensor unit surface.
Local load: 100 kg on an area 40 mm in
diameter.
Be sure to use the sensor unit on a flat
place so it will not bend. Otherwise, the
sensor may be damaged.

2. Notes for Using the Instrument
– 4 –
During Cleaning
Do not use anything other than neutral detergent for cleaning the cover of the instrument.
Otherwise, the coating will be corroded.
Storage
Be sure to store the sensor unit and the optional grid unit in a safe place where it will not
fall or drop.
Others
Be sure to reconnect the cables to the proper connectors. Otherwise, the instrument may
malfunction or may be damaged.
