Getting to Know Your
AVANT Polar HIT
The AVANT Polar HIT represents a new era of precision Hearing Instrument Testing for your office.
Compact yet rugged, this PC-Based system is USB powered and performs all required ANSI and IEC
tests. A unique feature of the Polar HIT is a rotating test pad, which allows you to generate polar plots
to verify the performance of directional microphones upon delivery and following repairs. The
following section of this manual will familiarize you with the physical features and accessories of the
Polar HIT system.

Rear View
Note the single high-speed USB 2.0 (backward compatible to USB 1.1) connector, which supplies the
unit with power and transmits software control and data acquisition.

Setting up the System
Install the Coupler Microphone
The Reference Microphone is pre-installed at the factory and should be flush or nearly flush with the
floor of the rotating test pad.
Carefully install the coupler microphone as shown in the images below. Take care when handling these
components, as they are delicate, precision calibrated instruments.
Install the Coupler Microphone as shown above.
Once the microphones are installed, you must install the Polar HIT Software and Drivers. This procedure
is detailed in the next sections of this manual. If you have difficulty with these steps, contact MedRx
Technical Support at [phone] or 727-584-9600.

Warnings!
• The use of accessories, transducers and cables other than those specified, with
the exception of transducers and cables sold by the manufacturer of the Avant
Polar Hearing Instrument Test box as replacement parts for internal components,
may result in increased emissions or decreased immunity of the Avant Polar
Hearing Instrument Test Box.
• The Avant Polar Hearing Instrument Test Box should not be used adjacent to or
stacked with other equipment. If adjacent or stacked use is necessary, the Avant
Polar Hearing Instrument Test box should be observed to verify normal operation
in the configuration in which it will be used.
• The Avant Polar Hearing Instrument Test Box may be interfered with by other
equipment, even if that other equipment complies with CISPR emission
requirements.
• The Avant Polar Hearing Instrument Test Box does not have life supporting
function
• Portable and mobile RF communications equipment can affect the Avant Polar
Hearing Instrument Test Box.

according to the transmitter manufacturer
and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site

NOTE 1 At 80 MHz and 800 MHz, the higher frequency ranges applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects 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 Avant Polar Hearing
Instrument Test box is used exceeds the applicable RF compliance level above, the Avant Polar Hearing
Instrument Test box should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the Avant Polar Hearing Instrument
Test box.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between
Portable and mobile RF communications equipment and the Avant Polar Hearing
Instrument Test box
The Avant Polar Hearing Instrument Test box is intended to use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the Avant Polar Hearing Instrument Test box can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Avant Polar Hearing Instrument Test box as recommended below,
according to the maximum output power of the communications equipment.
