TX FCC ID MHA02DSI
These devices comply with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This
device may not cause harmful interference, and (2) this device must except any interference that my cause undesired
operation.
Caution
Changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment.
Device Operation
All transmitters have two operational modes: On and Off. Transmitters are shipped in the Off mode, with the
batteries not activated. When switched to the On mode, the transmitters begin to sense and transmit data. The switch
to change modes is magnetically activated. Some transmitters have an additional Battery mode. This mode allows
the Dataquest ART software to determine the precise amount of battery life left towards the end of the transmitter’s
battery life. Refer to your transmitter label to determine if your model has the Battery mode.
All transmitters should be turned on 24 hours before use to allow the electronics to stabilize. The data from the
transmitters may not be completely accurate until this has occurred. For pressure implants, this can have an effect on
the pressure offset measurement; please see the section “Checking Accuracy Prior to Implantation” for more
information. For details on switching operational modes, please refer to the appropriate section of your surgical
manual.
Storage of Transmitters
It is crucial that transmitters be stored properly to avoid damage or unnecessary loss of battery life. These
instructions include the proper storage technique for both new and resterilized transmitters.
All transmitters should be carefully examined when they arrive at your facility. Remove the transmitters from the
shipping boxes. Save the shipping boxes and foam liners for returning used transmitters.
Inspect the transmitter package for signs of damage. Using your AM radio, confirm that the transmitter is turned off.
Although each unit is checked just before shipping, it is possible that the transmitter may have been exposed to stray
magnetic fields during shipment. This can cause the unit to be turned on unintentionally. All transmitters are sterile
upon arrival. If the package remains undamaged, this sterility is warranted according to the information on the
package label. Transmitters in the Off mode may lose up to 10% of the battery life within 12 months after the
manufacture date.
Transmitters should be stored in a cool (between 10 and 25 degrees Celsius), dry area away from exposure to static
discharge and magnetic fields. They should never be exposed to temperatures above 60 degrees Celsius, as this will
void all warranties. It is also important to store them in an area where they will not be accidentally dropped or have
items placed on top of them. Storage in a refrigerator does not provide significant benefit in terms of battery life. If
the implants are to be stored for an extended period of time, Data Sciences International (DSI) recommends periodic
checks with an AM radio to ensure the transmitters are still turned off.
Transmitters should be turned on 24 hours before use to allow the electronics to stabilize. Zero offset should be
checked on all pressure transmitters just prior to use to verify stability.
Storage of Resterilized Transmitters
DSI supports a method for on-site resterilization of transmitters. For transmitters used in short-term studies, this
allows multiple uses from a single unit before it is necessary to return it for refurbishment. Occasionally there may
be a delay between removal from the first animal and implantation in the next. Proper storage of the resterilized
transmitter is necessary to assure that the unit will function properly.
Following explantation, each transmitter should be thoroughly cleaned and resterilized according to DSI
resterilization procedure (please see the section on resterilization). Using your AM radio, each transmitter should be
