regular operation of these devices.

Switch off CT3MA on planes. Make sure it cannot be
switched back on accidentally.

Do not install CT3MA near oil stations, fuel deposits,
chemical plants or explosive sites since CT3MA could
interfere with the operation of technical equipment.

CT3MA could generate interference if used near TVs,
radios or PCs.

In order to prevent possible damages, only use accesso-

ries tested and certied as compatible with CT3MA

Safety Information

The use of CT3MA in life support systems or components is not al­lowed and, if required, it must be authorised beforehand in writing.

Life support systems are components or systems used to assist ar-

ticially the human body in its functions. In case of faulty operation,

these could cause injury to patients.

No complex hardware or software system can be considered perfect.
Faults can occur in systems of any kind.
To prevent damages to things and injuries to persons, it is up to the
designer to devise redundant protection methods, suitable for the
risk related to use.

Every CT3MA unit is submitted to complete functional testing.

Specications are based on the characterisation of the tested sample

unit and do not refer to measurements taken on each single manu­factured unit.

Operation

When CT3MA is connected to a Fantini Cosmi chronostat model
C46A, C55-56, C51-52-53-54, C75CT-76CT, CH15X, via SMS mes­sages it enables to read the chronostat status (ambient temperature
measured, programme set, etc.) to modify the set programme and to
change certain thermoregulation parameters (only for CH15X).
CT3MA can automatically send a SMS message to the phone num­ber stored inside it when an alarm conditions occurs (due to contact
clo-sing/opening).
NOTE: different alarms can be controlled by setting them parallel
with each other.

External antenna

Connect dual band antenna (GSM900/1800) to RF interface avail­able on CT3MAA model. Connection is obtained by connecting the
antenna to the SMA/F connector set on the top of the device.

Immunity against interference

Provide suitable protections against fast transients if the cable is lon­ger than 3m
