Introducing the Welch Allyn AED10 Trainer
Overview
The Welch Allyn AED10 Trainer is a training tool for preparing emergency responders to use
the Welch Allyn AED10 to treat a victim of sudden cardiac arrest. The Trainer provides
realistic simulation of the Welch Allyn AED10 without actually charging or discharging
electrical energy. Voice prompts, simulated energy delivery, pauses for CPR, training pads,
and the functional system status indicator all accurately mimic the operation of the Welch
Allyn AED10 and provide a realistic demonstration.
Ten different scenarios are available.
Multiple language selections are available.
Hand held IR remote control allows instructors to customize training sessions.
The Welch Allyn AED10 Trainer is intended for indoor use.
The Welch Allyn AED10 Trainer is not intended to teach basic life-saving skills.
Trainees should have completed an appropriate training class for knowledge in
assessing the patient, CPR (cardiopulmonary resuscitation), and correct medical
protocols.
Note: Training Pads should be used only with a “plastic skin” type mannequin.
Do not use on foam-based mannequins.
Caution
Trainer Pads are for demonstration purposes only and are not for clinical use.
Special Features
Voice prompts identical to those in the Welch Allyn AED10.
Text prompts identical to those in the Welch Allyn AED10.
Remote control for instructor use.

Operating the Trainer
Trainer Mode
Trainer mode is the primary mode of operation and is accessed by pressing the green ON/OFF
button. In this mode, the Menu buttons are inoperative and all menus are inactive. The
ON/OFF button and the Shock button are the only user responsive buttons in this mode. While
in Trainer mode the unit displays elapsed time, battery level, number of shocks delivered to
the patient, text prompts, and various status messages on the LCD display.
Elapsed Time: While in Trainer mode the elapsed time is displayed in the upper left hand
corner of the screen in the following format: HH:MM:SS. The Elapsed Time stops
incrementing if the Trainer is paused during a scenario and continues after the scenario is
resumed.
Battery Level: While in Trainer mode the Trainer graphically displays the battery level in the
upper middle portion of the screen. The battery level indicator displays 10 distinct battery
levels and is updated every second. The word “LOW” appears under the battery level symbol
if the average battery voltage falls below operating levels.
Patient Shock Counter: While in Trainer mode the unit displays the number of shocks
delivered in the upper right hand corner of the screen
AED Text: While in Trainer mode this region of the display shows text prompts to the user.
Status: The lower right hand corner of the screen displays the simulated amount of delivered
energy.

and give an AED Instructor a standard means of training and testing proficiency in AED use.
Scenarios 1 to 10 may be selected with the Menu Mode Scenario menu or with the Remote
Control. Scenarios 1 to 8 conform to the AHA recommended training scenarios. Scenario 9 is
the same as AHA scenario 2 except with a one shock conversion. Scenario 10 is the same as
AHA scenario 7 except with a one shock conversion followed by refibrillation. See the
following table of Training Scenarios.
The Scenario menu may also be used to select a continuous Shockable rhythm (11) or a
continuous Non-shockable rhythm (12).

Where P is the maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer and d is the recommended separation distance in meters (m).b
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey,c
should be less than the compliance level in each frequency range.d
Interference may occur in the vicinity of equipment marked with the following symbol:
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
a. The ISM (industrial, scientific and medical) bands between 150 KHz and 80 MHz are 6.765 MHz to
6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.
b. The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the
frequency range 80 MHz to 2.5 GHz are intended to decrease the likelihood that mobile/portable
communications equipment could cause interference if it is inadvertently brought into patient areas.
For this reason, an additional factor of 10/3 is used in calculating the recommended separation
distance for transmitters in these frequency ranges.
c. Field strengths from fixed transmitters, such as base stations for radio (cellular / cordless) telephones
and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be
predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be considered. If the measured field strength in
the location in which the Welch Allyn AED10 Trainer is used exceeds the applicable RF compliance
level above, the Welch Allyn AED10 Trainer should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the Welch Allyn AED10 Trainer.
d. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than
[V1] V/m.

The Welch Allyn AED10 Trainer is intended for use in an environment in which radiated RF
disturbances are controlled. The customer or the user of the Welch Allyn AED10 Trainer can
help prevent electromagnetic interference by maintaining a minimum distance between

For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in meters (m) can be determined using the equation applicable to the frequency of the
transmitter, where P is the maximum output power rating of the transmitter in watts (W) according
to the transmitter manufacturer.
Note 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note 2: The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6.765 MHz to

Note 3: An additional factor of 10/3 is used in calculating the recommended separation distance for
transmitters in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range
80 MHz to 2.5 GHz to decrease the likelihood that mobile/portable communications equipment could
cause interference if it is inadvertently brought into patient areas.
Note 4: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
