| Is
it possible to have a Model 3000 amplifier customized
for my preferred gain and filter settings? |
| Yes,
in most circumstances, we can easily customize at our
factory any of our amplifiers' filter and/or gain settings.
Please contact technical support (800-426-1306, or tech@a-msystems.com
for more information.

| Do
you sell extension cables for your headstages? |
| We
do not sell extensions, however we do sell new headstages
with longer cables (for a small customization charge).
The maximum length is usually 12 feet. Typically, the
main amplifier needs to be returned to us for calibration
with the new longer headstage cables.

| What are the
differences between the two headstages? |
| The Regular
Headstage supports all of the functions performed by the Model 3000.
Some users would prefer a smaller headstage. In order to accommodate
them, we have designed the mini-headstage, which is smaller in length
(same diameter). To accomplish this, the circuitry that enables the
Model 3000 to pass current to the electrode, or determine the impedance of
the electrode in-vivo has been removed. Therefore, these functions
are in-operative while using the mini-headstage.

| My
Model 1800 is not working, but our university has an
excellent electronics facility. Can we repair the unit
ourselves? |
| It
is recommended that A-M Systems perform the needed repairs
as we are the most familiar with the units. However,
if you are confident in your electronic technician's
skills, you can always purchase the schematics for the
from us and attempt them yourself.
Please note that any user-attempted repairs during the
warranty period may invalidate the warranty, and might
invoke additional charges to correct them if A-M Systems
is required to make repairs at a later date.

| Should
I purchase a Model 1800 or a Model 3000? |
Both
instruments are designed for low noise differential recording of
physiological signals. The Model 3000 has a DC front end, which also
enables the researcher to record DC offsets that would otherwise be
eliminated by a full AC amplifier, like the Model 1800.
The Model 3000
also has capacity compensation during recording as well as impedance
measurement, while the Model 1800 only uses capacity compensation during
impedance measurement.
The Model 1800
has lower noise than the Model 3000, but both instruments have acceptable
noise levels for high quality recordings.
The Model 3000
can fit within a Faraday cage, as its power input is DC from the remote
power supply.
The Model 1800
has two channels, and two headstages are included. In contrast, the
Model 3000 has only a single channel, and headstages are options available
for an additional charge.

| Can
I use this instrument outside of the United States? |
| All
of A-M Systems instruments can be modified to work outside
of the United States. Typically, this modification is
made at the factory (at no additional cost) prior to
shipping to our customers. Just inform the customer
service department where the instrument will be used,
so our technicians can prepare the proper power supply
modifications.

| What
are the proper operating and storage conditions for
my Model 3000? |
| The
Model 3000 is designed to be used under laboratory conditions.
Operate in a clean, dry environment only. Do not operate
in a damp environment. Temperatures for storage and
operation should be between 5 °C and 40 °C. Storage
should be indoors in a cool dry place.
