WARNING
DC Port and A/C Adapter
Connecting and Operating the Analyzer while using the A/C or D/C adapters can create external
sparks during connection. Connecting or use of these power sources in an explosive atmosphere is
dangerous and should never be attempted. Always connect the MRI-3000 away from any explosive
atmosphere. Use ONLY internal battery power if the presence of explosive fumes is a potential
hazard.
Coax Test Ports
The presence of any voltage, from an applied source or static build-up on cables or antennas, particularly
vacant cables with no terminations or grounding, can cause an ignition spark when they are connected
to the MRI Analyzer. Caution should be taken to ensure cables are free of any voltages or static charge
prior to connecting the instrument in a potentially explosive atmosphere.
Operating Precautions
Although the Bravo MRI 3000 is a rugged instrument, care should be taken to avoid exposing it to
excessive external RF or a Magnetic Field. Do not connect the Bravo MRI to an active transmitter.
The Bravo MRI Should Not be allowed to get closer than 3 feet (1 meter) with a 1.5T Coil, and 5 feet
(1.5 meter) with a 3T Coil
The MRI Analyzer, when in its Belt Case, is splash resistant and designed to work for relatively long
periods in rain depending on intensity. It is not designed to be immersed in water. See Cleaning
Instructions in the appendix.
The Test Port is limited to +15dBm input power. Power exceeding this level could damage sensitive
input components.
Batteries
Due to the strong magnetic fields involved with MRI servicing, the use of batteries is not
recommended. Both the Bravo MRI unit and the MRI unit under test could be more susceptible to
damage if batteries were installed. for convenience we provide a 20 ft long DC extension cord to use
with the Ac adapter plug, if you must use batteries follow operating precautions instruction and keep
the analyzer a min of 3 feet (1 meter) away from the magnet
When batteries are required you can use Alkaline, NI-MH, LiION "AA" Batteries in the MRI Analyzer,
but when installed go to the Battery Menu and change the Battery Type to ALKALINE, Rechargeable
or NON.
Please note rechargeable batteries can't be charged inside the unit.
Cleaning
Under ordinary operating conditions, it should only be necessary to occasionally wipe the VIA Bravo
MRI with a soft, water moistened cloth. Avoid using solvents which may attack the plastic.
