If any of the parts listed in the packing list are missing, contact your special equipment
distributor or TREMETRICS. We recommend that you save the shipping box and
packing materials in case you need to store or ship the device.
SAVE ALL THE ORIGINAL PACKING MATERIAL AND THE SHIPPING CONTAINER
SO THE INSTRUMENT CAN BE PROPERLY PACKED IF IT NEEDS TO BE
RETURNED FOR SERVICE OR CALIBRATION.
Notify the carrier immediately if any mechanical damage is noted. This will insure that
a proper claim is made. Save all packing material so the claim adjuster can inspect it
as well. Notify your dealer or TREMETRICS when the adjuster has completed the
inspection.
4.2 Where to setup
Setting up your RA660 make sure that the operation environment meets the following
requirements:

The test room must be at a normal temperature, (Conditions can be found in
section 6.1), and the instrument should be switched on approximately 10 minutes
before the first measurement. If the device has been cooled down (e.g. during
transport), please wait until it has warmed to room temperature before using.
You shall also consider the influence of direct sunlight as well as the relative
position to other devices that can produce heat or humidity, and provide an
appropriate cooling if necessary.

The RA660 should be operated in a quiet room, so that the audiometric
examinations are not influenced by outside noises. Ambient sound pressure
levels in an audiometric test room shall not exceed the values specified in the
norm ISO 8253-1:2010 or ANSI S3.1-1999. For use in noisier environments,
headphones with sound insulation muffs are available.

Electro-medical instruments, which emit strong electromagnetic fields (e.g.
microwaves or radiotherapy devices), can influence the function of the
audiometer. Therefore, it is not recommended to the use these instruments in
close proximity to the audiometer as it may lead to incorrect test results.

Since in case of emergency you shall pull out the plug, make sure you place the
device in a way that enables you to pull out the plug easily if it becomes
necessary.
External devices such as a computer, printer or Ethernet
which are connected to the device must meet electrical
safety requirements, please refer to section 2.7
