Portable and mobile RF communications
equipment should be used no closer to
any part of the CXDI-55G, including
cables, than the recommended separation
distance calculated from the equation
applicable to the frequency of the transmitter.

where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d
is the recommended separation distance
in metres (m).

Interference may occur in the vicinity of
equipment marked with the following symbol:
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.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot 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-55G is used exceeds the applicable RF compliance level
above, the CXDI-55G should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the CXDI-55G.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

WARNING
CAUTION
Do not turn ON the system power when condensation is formed on the instrument. Otherwise, it may result in fire or electric shock.
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.
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.
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.
Do not hit or drop the instrument. The instrument may be damaged if it

ment is used without it being repaired.
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 necessary.

1. Overview
The Canon Digital Radiography CXDI-55G is a portable digital radiography 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.
The instrument is suited for use inside a patient environment.

2. Notes for Using the Instrument
(1) 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. Other
wise, the cable may be damaged,
which may result in fire or electric
shock.
-
When transporting the instrument,
do not allow the sensor cable relay
connector to drag on the floor or
ground or bump against anybody or
any articles of property. It is recom
mended to hold the cable while
transporting the instrument.
Otherwise, the connector get caught
by, bump against somebody result
ing in injury or cause damage to the
property items and/or connector
itself as a result.
-
-
(2) Before Exposure
Sudden heating of the room in cold areas will cause condensation to form on the
instrument. In this case, wait until condensation disappears before performing expo
sure.
If the instrument is used with condensation formed on it, problems may occur in the
quality of the instrument.
When an air-conditioner is going to be used, be sure to raise/lower the temperature
gradually so that a difference in temperature in the room and in the instrument does
not occur, to prevent forming of condensation.

4.1 Turning ON/OFF the Power of the System
When turning ON/OFF the power of the sensor unit, refer to the Power Box (sold separately) Operation Manual.
4.2 Calibration
Calibration is important to ensure that a good image is achieved with the CXDI-55G by
obtaining the calibration data of the sensor unit. Perform calibration when exposure condi
tions have changed significantly.
NOTE: For procedure for calibrating, refer to “Calibrating the Instrument” in the CXDI
Series Operation Manual.
4.3 Connecting and Disconnecting the Sensor Cable Relay
-
Connector
Follow the steps below to connect or disconnect the sensor cable relay connector.
NOTE: Do not connect this sensor unit to the power box other than CXDI SYSTEM II.
It may cause damage to the connector.
In addition, it is necessary to register each sensor unit to the software for controlling the system.
For details on registering the sensor unit, contact Canon representative or distributor.
NOTE: When connecting or disconnecting the sensor cable relay connector, refer to the
CXDI Series Operation Manual, set the power switch on the power box (or
remote switch) to OFF and check that the POWER lamps on the sensor unit,
power box and remote switch are off.
The ERROR lamp will light if the connector is connected or disconnected while
the POWER lamp is lighted.
NOTE: Be absolutely sure to hold the sensor cable relay connector by its grip part to
connect or disconnect it.
Holding the cable to connect or disconnect the connector may break the wires
inside the cable.
If the outer bushing of the grip part is turned, the cable lock can be loosened, and
this can cause a short-circuit of the cable.
NOTE: Do not drop the sensor cable relay connector when connecting or disconnecting
it. You may injure yourself or cause damage to the property or connector.
