earphone coupler or while worn on the ear of the end user. It consists of:
a) an integrated acoustically-treated test chamber which houses an optional battery substitute (1.3 volt supply),
loudspeaker (which doubles as a sound-field speaker), a reference microphone for controlling the signal from the
loudspeaker, and a standardized earphone coupler connected to a measuring microphone for the purpose of
measuring the sound level produced in the standard coupler by a hearing aid.
b) a flat-panel video display, power supply, signal generation, measurement and control electronics and a custom
keypad.
c) a real-ear measurement microphone assembly housing a reference microphone for controlling the signal from
the sound-field speaker and a probe microphone connected to a thin silicone tube which may be inserted into the
ear canal for the purpose of measuring the sound level in the ear canal produced by a hearing aid.
d) an optional miniature earphone used to measure the real-ear to coupler difference (RECD) useful in
estimating the sound level produced in an individual ear from measurements in the standard earphone coupler.
There is a connector for USB devices (flash drives, a Q ERTY keyboard, mouse, printer, barcode scanner), a
LAN port, and two auxiliary audio output connectors (not supported in this version of software). Units with

RM500SL®User's Guide Version 3.16  October 2016
How to Avoid Undesirable Side Effects
During the development of the hearing aid analyzer, Audioscan performed a rigorous Risk Assessment to
identify any undesirable side effects that a user could be exposed to during the use of the RM500SL, and
incorporated numerous risk reduction design elements into the RM500SL to minimize the risk to users and
patients.
Following are the actions which a user should take to ensure that these risk control measures continue to be
effective
Loud Sounds:
The RM500SL is designed to produce sound pressure levels as high as 85 dB at the probe reference microphone.
Exposure to these levels for more than 7 hours can produce hearing damage. hen such levels are amplified by
a hearing aid, the level in the ear canal will be determined by the settings of the hearing aid but may reach levels
that can produce hearing damage in less than 30 seconds. To avoid this possibility,
1. hearing aids should be adjusted to limit sound pressure levels to safe levels
2. the maximum TM SPL setting (see Max TM SPL Setup) should be used to terminate tests if an unsafe level
is detected in the ear canal
3. test levels should be limited to 70 dB SPL except when necessary to verify the limiting levels of the hearing
aid, in which case, the test should not last longer than 15 seconds
4. be aware of the test signal and patient reaction during a test and be prepared to respond to any sign of
discomfort by reducing the SPL setting, switching off the equipment or the hearing aid, or removing the
patient from the area.
hen using the equipment to measure the Real-Ear to Coupler Difference in small ear canals, it is possible to
induce a hearing loss if the test is allowed to continue for more than 1 hour. Since accurate results can be
obtained in less than 10 seconds, this possibility should never occur in normal practice.
Power and Grounding:
This product contains numerous safety features to ensure that the probability of electrical shock is as low as
reasonably practicable. In order to ensure that all of the safety features work optimally you must ensure that the
power cord is plugged into a grounded outlet. Any line-powered peripherals connected to the RM500SL must
comply with UL/IEC 60601-1 OR comply with UL or IEC or ISO safety standards for such equipment, AND a)
be operated from an isolating transformer complying with UL/IEC 60601-1, OR b) be kept at least 6 feet (1.8m)
from the patient.
Ear Infection:
Probe tubes or RECD foam tips should not be re-used on another patient. There is a possibility of transferring an
ear infection to the other patient. Probe tubes and RECD foam tips are for single-patient use only. Do not
attempt to clean or re-use.
Ear Canal Discomfort:
An otoscopic examination should always be performed prior to inserting a probe tube into the ear canal to ensure
that it is healthy and free of obstructions. Care is needed when inserting probe tubes into the ear canal. Although
the probe tubes are made of soft, flexible material specially designed for this application, it is possible to scrape
the ear canal or touch the eardrum causing brief discomfort. You should carefully follow the instructions in
“Positioning the probe tube” section of this User’s Guide.

2 Getting Started
This section provides instructions for unpacking the RM500SL and connecting various components and
associated items. Note that battery pills (SL-110), the RECD transducer (SL-100), the barcode scanner (VA-120)
and a microphone extension cable (VA-131, VA133) are associated items which must be ordered separately.
Unpacking and connecting
WARNING: To avoid the risk of electrical shock, use only the power cord supplied with the RM500SL and
connect it only to a grounded (protectively earthed) electrical outlet.
WARNING: To allow electrical power to be rapidly disconnected in the event of an emergency, position the
RM500SL in an accessible location so that the power cord may be quickly disconnected.
WARNING: To ensure that the operation of this product is not affected by EMC emissions from other
products, this product should not be used adjacent to or stacked on other equipment. If this is necessary, its
operation should be verified as normal in this configuration. Portable and mobile RF communications
equipment can affect the performance of this product
Failure to follow operating instructions could place the user or operator at risk.
1. Carefully unpack the RM500SL and check the contents of the shipping box against the enclosed packing list.
Note that some parts may be packed inside the test chamber.
2. Unwrap the power cord from its stowage hooks - noting carefully how it has been packed. To avoid serious
damage to the display screen, always repack the cord this way.
3. Connect the power cord to the socket next to the power switch on the right side of the unit. Plug the other end
into a grounded 100 – 240 volt power outlet.
Microphone connection
1. Plug the reference microphone and the coupler microphone into the connectors in the test chamber as shown.
14

RM500SL®User's Guide Version 3.16  October 2016
2. Plug the probe microphone assembly into the probe connector located at the left of the test chamber as
shown.
NOTE: A microphone extension cable (VA-131, 133) is available from Audioscan. Standard audio extension
cables should not be used. They will substantially increase noise levels.
General care instructions
Probe tubes are for single patient use only. They may be wiped with alcohol wipes for re-use with the same
15

RM500SL®User's Guide Version 3.16  October 2016
patient, but must not be used with multiple patients. Attempts at ultrasonic cleaning usually result in cerumen
becoming lodged in the lateral end which causes irreparable damage to the probe microphones.
The case can normally be cleaned/dusted with a damp cloth, however if it is soiled we recommend wiping with a
mild solution of water and detergent, or with alcohol-impregnated wipes deemed safe for use on electronic
equipment. Parts that come into contact with patients (the probe module body, cable, and blue lanyard) should be
regularly wiped down with alcohol wipes.
Hearing instruments should be cleaned prior to introduction to the test chamber due to the difficulty of sanitizing
the acoustic foam. Custom hearing instruments must be cleaned with disinfectant towlettes (i.e. audiowipes)
prior to placing in the test for this reason and to minimize contamination of the blue putty used with the HA-1
coupler. The acoustic foam in the floor of the test chamber is easily removed and should be replaced if badly
worn or soiled.
Audioscan recommends periodic replacement of the blue putty used with the HA-1 coupler to ensure cleanliness.
Both couplers and coupler mic can be wiped down with alcohol wipes as needed.
Ensure that all safety and usage recommendations on cleaning product packages are followed.
Microphone care
Coupler microphone:
1. DO NOT twist the cable when attaching a coupler to the coupler microphone. Turn only the coupler or
unplug the coupler microphone before turning it.
2. DO NOT leave the coupler microphone plugged in when transporting.
3. DO make sure that the 2cc coupler is tightly screwed to the coupler microphone when performing hearing
instrument tests. Coupler leakage can cause feedback and erratic response curves.
4. DO make sure the tubing on the BTE (HA-2) coupler is free from any cracks/tears.
5. DO make sure that any replacement tubing used on the BTE coupler is either obtained from Audioscan, or is
#13 heavy wall earmold tubing exactly 10 mm in length.
Pro e microphone:
Debris can alter the probe module reference microphone calibration and frequency response and can
permanently clog the probe module port.
1. DO NOT reuse probe tubes. Probe tubes can be wiped with alcohol wipes for re-use with the same patient,
but must not be used with multiple patients. Attempts at ultrasonic cleaning usually result in cerumen
becoming lodged in the lateral end which causes irreparable damage to the probe microphones.
2. DO NOT attempt to open or repair the probe microphone. Attempting to repair the probe module may lead
to damage or alteration of the factory calibration.
3. DO keep the probe module and probe tubes in a clean area.
4. DO stow the probe module when not in use or when transporting the RM500SL.
Battery pill use and care
Battery pills are optional. The thin connecting strip of each battery pill is fragile. hen inserting pills into
hearing instrument battery compartments, take care that this strip is not pinched or bent severely as the battery
door is closed.

In Speechmap and Insertion gain tests, audiometric data in barcode form on an Audioscan analyzer printout may
1

RM500SL®User's Guide Version 3.16  October 2016
be entered by scanning the appropriate barcode. In Speechmap, air and bone threshold, UCL, RECD,
audiometric transducer, age and ABR nHL to eHL conversion factors are encoded. In Insertion gain, threshold
and transducer type are encoded. The type of data and the ear (left, right) is shown below the barcode. Only data
for the displayed ear are imported. Barcodes may be scanned in any order and it does not matter if the barcode is
'upside down'.
1. Select Speechmap or Insertion Gain from the Tests menu.
2. Hold the printout so that the barcode is flat. ith the scanner 6 – 8 in. (15 – 20 cm) from the barcode, press
