Unpacking and Inspection
Follow standard receiving practices upon receipt of the instrument. Check the shipping carton for damage. If
damage is found, stop unpacking the instrument. Notify the freight carrier and ask for an agent to be present
while the instrument is unpacked. There are no special unpacking instructions, but be careful not to damage the
instrument when unpacking it. Inspect the instrument for physical damage such as bent or broken parts, dents,
or scratches.
Claims
Our routine method of shipment is via common carrier. Upon delivery, if physical damage is found, retain all
packing materials in their original condition and contact the carrier immediately to file a claim.
If the instrument is delivered in good physical condition but does not operate within specifications, or if there are
any other problems not caused by shipping damage, please contact your local sales representative or DSI
immediately.

Warranty
Warranty and Product Support
Datrend Systems Inc. ("DSI") warrants the Base and Simulation Modules of vPad-A1 (the "Datrend product") to
be free from defects in materials and workmanship under normal use and service for one (1) year from the date
of original purchase. This warranty will be automatically extended to two (2) years from the date of original
purchase, provided that calibration is performed on an annual basis by a Datrend Authorized Service Center*.
During the warranty period DSI will, at our option, either repair or replace defects in materials and workmanship
at no charge; provided the Datrend product is returned (shipping, duty, brokerage and taxes prepaid) to DSI.
Any and all transportation charges incurred are the responsibility of the purchaser and are not included within
this warranty. This warranty extends only to the original purchaser and does not cover damage from abuse,
neglect, accident or misuse or as the result of service or modification by other than DSI. IN NO EVENT SHALL
DATREND SYSTEMS INC. BE LIABLE FOR CONSEQUENTIAL DAMAGES.

Warranty Disclaimer
Should you elect to have your instrument serviced and/or calibrated by someone other than Datrend Systems or
an Authorized Service Centre, please be advised that the original warranty covering your product becomes void
when the tamper-resistant Quality Seal is removed or broken without proper factory authorization. We strongly
recommend, therefore, that you send your instrument to Datrend Systems or an Authorized Service Centre for
service and calibration, especially during the original warranty period.
In all cases, breaking the tamper-resistant Quality Seal should be avoided at all cost, as this seal is the key to
your original instrument warranty. In the event that the seal must be broken to gain internal access to the
instrument (e.g., in the case of a customer-installed firmware upgrade), you must first contact Datrend Systems
at 1-604-291-7747. You will be required to provide us with the serial number for your instrument as well as a
valid reason for breaking the Quality Seal. You should break this seal only after you have received factory
authorization. Do not break the Quality Seal before you have contacted us! Following these steps will help
ensure that you will retain the original warranty on your instrument without interruption.
WARNING
Unauthorized user modifications or application beyond the published specifications may result in electrical
shock hazards or improper operation. Datrend Systems will not be responsible for any injuries sustained due to
unauthorized equipment modifications.
DSI DISCLAIMS ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING ANY WARRANTY OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR APPLICATION.
THIS PRODUCT CONTAINS NO USER-SERVICEABLE COMPONENTS.
UNAUTHORIZED REMOVAL OF THE INSTRUMENT COVER SHALL VOID
THIS AND ALL OTHER EXPRESSED OR IMPLIED WARRANTIES.
Note: Calibration of Datrend products typically involves adjustment of parameters stored in firmware by proprietary
software. Parties other than Datrend and its Authorized Service Centers are limited to verification of the status of
the accuracy of the instrument. Do not confuse verification with calibration.

1 Specifications
The vPad-A1 All-In-One patient simulator and performance tester is a modular, stackable system comprised
of a user interface or "base" module providing a tablet computer, system power and communications, and
one or more of the following modules: a patient simulator (ECG, IBP, RESP, etc.); a pulse oximeter (SpO2)
tester; and an NIBP simulator. Each simulation/test module can be used individually with the base, or in
combination with either or both of the other modules. The base module includes hardware for charging an
internal battery which provides power to the base, the pulse oximeter tester, and the ECG/IBP simulation
module. The vPad-A1 software or "app" runs on the tablet computer and is used to operate the
simulation/test modules.
The following specifications pertain to the vPad-A1 hardware when used with the vPad-A1 software or
"app" on the tablet. As a modular system, product capabilities will depend on the modules present;
specifications apply only to those modules that you have active in the system.
Equipment Performance Specifications
1.1 General Specifications
User Interface:
The simulation hardware of vPad-A1 is controlled by a tablet computer through a hardwired
connection to the microUSB port on the tablet, or alternatively through wireless communication
with the tablet over Bluetooth. The tablet computer is comparable in size to a conventional
smartphone and fits into a cradle on the vPad-A1 base module for storage and transport.
A software application or "app" running on the tablet controls the system. As individual simulation
functions are activated by the app, they remain active until explicitly turned off. The app enables
numerous simulations to run concurrently, with all patient signals remaining in synchronization.
The tablet computer of vPad-A1 has these specifications:
