Introducon
Congratulations on your purchase of a MindWare Mobile Recorder unit. The
device you hold in your hand is the result of many years of development in
and use of the unit. There are sections throughout the text that are unique to the
warnings. These sections are indicated by the following symbols:

Device Overview
DC Charger Port and Charging LED
e DC Charger Port interfaces with the supplied medical-grade DC power supply. It is
safety-isolated to allow charging the unit while it is in use.
!
To ensure safety, use only the provided medical-grade power supply
e charging LED turns on when the power supply is connected and the battery is charging.
It turns o when the battery is charged or power is lost. e LED blinks if the temperature is
too high, too low, or battery needs to be replaced.

When the battery is low, the unit will beep every 10 seconds. This stops
when charging starts or after two minutes, when the unit stops any
acquisition and turns off.
SD Card Slot
e Mobile accepts full sized SD and SDHC cards in the SD card slot. It is designed
such that the SD card is ush with the case when inserted to prevent accidental removal
during acquisition. e depression in the middle of the slot allows the card to be inserted
or removed by pushing with a ngernail, pencil eraser, or other blunt object.
We recommend using SDHC cards for their increased performance.
Display and Light Sensor
In the interest of increasing battery life, the Mobile uses a low-power LCD screen with
the ambient light sensor to limit the backlight intensity during use. Any key press will
wake up the backlight for a short period of time.
Keypad
e keypad consists of two context buttons (A and B), four arrow buttons, and a Run (
) button. e arrow buttons are used for navigation and unlocking the unit during
acquisition. e button is the power button for the unit and also functions as an
OK or Select button, depending on what is on the screen. e context buttons change
function depending on text on the screen above them, or they act as event buttons
during acquisition. In many situations, the button duplicates the functionality of
context button B.
Use the context buttons during acquisition to mark events.

GND Black None Ground
Input Channels
e input channels are 1.5mm safety jacks that accept the supplied leads and connect to
electrodes on the subject. For ease of identication, the following are the inputs broken
down by names and colors:
EKG, EMG, EOG, Respiration, and Other General Voltage Signals
BIO1 and BIO2 are differential, DC-coupled voltage input channels with the following
gains and associated ranges and resolutions:
Gain Range (V) Resolution (nV)
1X +/- 2.4 286
2X +/- 1.2 143
3X +/- 0.8 95.4
4X +/- 0.6 71.5
6X +/- 0.4 47.7
8X +/- 0.3 35.8
12X +/- 0.2 23.8

while respiration is measured with a sensor such as a piezoelectric respiration belt.
Various other sensors and devices with voltage outputs can be interfaced to these
channels as long as they are independently powered or produce their own voltage,
such as piezoelectric sensors.
Using the previous table, choose a gain with one range larger than the
expected limits of the signal being recorded to accommodate any variation
in the signal. When in doubt, run various test subjects at the highest range
(lowest gain) and adjust based on the range of data observed.
!
Individual channel ranges will vary slightly from unit-to-unit but the
calibration of each unit will correct for this variation to record accurate data.
!
Never connect other equipment to any of the Mobile inputs unless the output
of the equipment is also isolated for the safety of the subject. Safety isolated
inputs on other equipment does not guarantee that the outputs are also
isolated.
Cardiac Impedance
The Constant Current Source (CCS) and Sense (SNS) signals make up the cardiac
impedance measurement. The CCS lines are a constant current source at 500uA,
100kHz and the SNS lines measure the magnitude of the resulting 100kHz signal
received, which is recorded as the Z0channel. A derivative of this signal is performed
in hardware and recorded in the dZ/dt channel.
!
The dZ/dt channel is recorded as an inverted derivative to match the
convential representation of the signal.

Galvanic Skin Conductance
The Galvanic Skin Conductance channel (GSC) is used to measure electrodermal
activity (EDA). It measures conductance by placing 0.5V between the electrodes and
that does not need a ground connection.
Ground
The ground (GND) connection is intended to keep the Mobile unit and the subject at
approximately the same DC potential to keep the signals within the input range of the
device (+/- 2.4V). The ground line needs to be attached to the subject at a location
with a minimum of muscle and possible movement.
Activity
There are three accelerometer channels, X, Y and Z, which are internal to the Mobile
unit. These can be used to assess activity levels, identify motion as the source of noise
in the other channels, and can estimate the posture of the subject.
