Using the emitter EMET‑HD
The EMET‑HD emitter is an instrument for measuring cardiac, respiratory and
activity physiological signals.
The function of the device is to acquire these signals then to transmit them
via a radio link (BLE 4.0) during acquisitions that can last from a few
minutes up to 24 hours.
It is intended for use in a laboratory environment for preclinical and
clinical research purposes.
When in use, this emitter connects to various sensors integrated into a vest
worn by the subject as well as to electrodes allowing the recording of
biopotentials.
Precautions for use
- When not using the EMET‑HD emitter for an extended period of time, remove the battery.
- The EMET‑HD emitter operates under the following environmental conditions:
- Indoor use
- Altitude between 0 and 2000m
- Temperature between 5°C and 40°C
- Pollution Degree 2
- Humidity between 10% and 90%
Material list
Bluetooth Low Energy emitter
The Bluetooth emitter is placed into the jacket backpack. It acquires data
from the ECG and RIP sensors.
Each emitter is identified by a unique number starting with 0E indicated on
the label.
Battery pack
The emitter is powered by a battery pack with a capacity of 250mAh. The
battery pack is removable and rechargeable by a USB cable plugged into the
acquisition server, a PC or any phone charger.
Using the DECRO emitter
The DECRO emitter has different connectors which are detailed in the table
below. Depending on the experimental setup, not all of them will necessarily
be used
- Connector to the jacket: Inductance Respiratory Plethysmography sensors
- Connector for ECG surface electrodes
- Emitter status LED1
Power on, power off, charge
Power on
- Insert the charged battery pack into the slot provided for this purpose
- The diode (3) briefly flashes Blue then Red and turns off. This means that the emitter is powered and ready for connection
Power off and storage
When storing, the battery should be removed from the emitter so that it does
not discharge before the next use.
- Press the lock
- Pull the battery out to remove it from its slot.
Charging the batteries
The batteries are charged using a USB cable plugged into the USB port of a PC,
the acquisition server or a smartphone‑type USB charger.
Here are the steps to follow: 1. Insert the USB cable; 2. The LED is orange
while charging; 2. The LED turns green when the battery is fully charged. Full
charge takes about 3 hours when the battery is empty

FCC Compliance:
FCC ID: 2A3MD‑GC930058
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Caution: the user that changes or modifications not expressly approved by the party responsible for compli‑ ance could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pur‑ suant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harm‑ ful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular in‑ stallation. If this equipment does cause harmful interference to radio or television reception which can be determined by turning the equipment off and on, the user is encouraged to try to correct interference by one or more of the following measures: ‑ Reorient or relocate the receiving antenna. ‑ Increase the separation between the equipment and receiver. ‑ Connect the equipment into an outlet on circuit different from that to which the receiver is connected. ‑ Consult the dealer or an experienced radio/TV technician for help.
FCC radiation exposure
This device complies with FCC RF radiation exposure limits set forth for
general population. This device must be installed to provide a separation
distance of at least 20cm from all persons and must not be co‑located or
operating in conjunction with any other antenna or emitter.
Environment of use and definition of the level of performance
Environment of use: The device is intended for use in a laboratory which
constitutes an industrial electromagnetic environment for its immunity and its
ElectroMagnetic Compatibility (EMC) have been tested according to standard
EN‑61326‑1
Performance level of the sensors: For the sensors, the performance of the device is evaluated according to its signal‑to‑noise ratio defined as follows and for a measurement duration of one second
The device is considered to be in default if the performance threshold is crossed more than 3 times in a row. The thresholds retained for the tests are indicated in the table below.
| Sensor | SNR threshold (dB) | Number of faults observed |
|---|---|---|
| ECG | 2 | 0 |
| RIP ABD et THX | 1.4 | 0 |
| ACC X,Y,Z | 1.4 | 0 |
Radio link performance level: The performance of the device is defined as the absence of loss of connec‑ tion. No disconnection was observed during immunity testing. The device is faulty if it cannot reconnect automatically.
Cleaning
To avoid any risk of damage to the Emitter {{hw‑ref}:
- Remove the battery from the emitter before cleaning the device.
- do not immerse the battery or the emitter in water.
- It can be cleaned with laboratory detergents: Alcoholic solutions or solutions without Alcohols based on Aldehydes (ie Didecyldimethlammonium chloride) in the form of a spray or wipes.
Cleaning the device
- Spray a cloth with the previous solution
- Rub the emitter and the battery with the cloth soaked in the solution
- Reuse the battery and emitter once they are completely dry.
