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.

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.

Proper planning will make your Mobile experience go smoothly. Before an acquisition,
fully charge the Mobile unit, check for dry or expired electrodes, and check for broken
leads.
Charging
To charge the unit, plug the supplied charger into
an outlet and into the Mobile. A Green light by
the charging port will illuminate while the unit is
charging. A full charge will take approximately four
hours from a low battery state. If the unit has been unused for a long time, it may need
to charge for an extended period before turning on. In this case, the clock may need to
be reset. See the section on Setting the Clock for instructions.
 While the unit is off and charging, a battery is displayed on the screen with:
o A lightning bolt and charge percentage during charging
o A checkmark when fully charged
 When the unit is powered on, most screens display a battery charge indicator
in the top left corner
 The battery charge level indicator and percentage are only an approximation
of the charge of the battery. The unit begins beeping when the battery is low,
then stops acquisition after two minutes to preserve data before shutting down.
 International plug kits are available for the charger. Contact a sales
representative to order one.
!
Note: The battery will continue to trickle charge even after the charge light
goes out and the unit indicates that it is charged. To maximize your runtime,
allow the unit to continue to charge in this state for a few hours before
disconnecting.

Lead Wires
Unfortunately, durable leads are uncomfortable to wear and comfortable leads are
fragile. The leads supplied with your Mobile unit are designed with a balance of
durability and comfort. When treated well, they can last a long time:

Time Estimate
When an SD card is inserted and initialized, the unit displays an estimate of the
recording time available on that card. This is a worst-case estimate based on all

Pre-Acquisition
The purpose of the pre-acquisition state is to allow you to
preview the signal morphology to verify that electrodes
are placed properly and hooked up correctly. The Left and
Right buttons allow you to cycle through each of the enabled
channels. After verifying signals, Context Button B will start the
acquisition or Context Button A

Do not be alarmed if it appears that the timer is not
counting up. It is designed to only update every 5 seconds
to maximize runtime.
Unlocking Acquisition
Acquisition is unlocked by holding the left and right arrow
buttons at the same time. This puts the acquisition into a mode
similar to pre-acquisition where signals can be viewed. Use the left and right arrows
to cycle through the different signals. This is useful for checking on electrodes
between phases of a study.
The acquisition will stay unlocked for 10 seconds after any key press and then
automatically return to the locked state. No events can be recorded while unlocked.
