1. Usage/Safety Considerations

1.1 Usage Conditions

Do not use the 3-Space Sensor in any system on which people's lives depend(life support, weapons, etc.)

Because of its reliance on a compass, the 3-Space Sensor will not work properly near the earth's north or south pole.

Because of its reliance on a compass and accelerometer, the 3-Space Sensor will not work properly in outer space or on planets with no magnetic field.

Care should be taken when using the 3-Space Sensor in a car or other moving vehicle, as the disturbances caused by the vehicle's acceleration may cause the sensor to give inaccurate readings.

Because of its reliance on a compass, care should be taken when using the 3-Space Sensor near ferrous metal structures, magnetic fields, current carrying conductors, and should be kept about 6 inches away from any computer screens or towers.

Since the Wireless 3-Space Sensor uses RF communication technology, communication failure modes should be carefully considered when designing a system that uses the wireless 3-Space Sensor.

The Wireless 3-Space Sensor is powered by a rechargeable lithium-polymer battery. Lithium-polymer batteries have high energy densities and can be dangerous if not used properly. See section 1.4 Battery Considerations for further information pertaining to battery safety.

1.2 Technical Support and Repairs

Limited Product Warranty: YEI warrants the media and hardware on which products are furnished to be free from defects in materials and workmanship under normal use for sixty (60) days from the date of delivery. No warranties exist for any misuse. YEI will repair or replace any defective product which is returned within this time period.

Product Support: YEI provides technical and user support via our toll-free number (888-395-9029) and via email

For damage occurring outside of the warranty period or provisions, customers will be provided with cost estimates prior to repairs being performed.

1.3 Regulatory Approval

1.3.1 United States FCC Approval

This device contains FCC ID: OA3MRF24J40MA

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful 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 instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. 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 the 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 a circuit different from that to which the receiver is connected.

Consult the dealer or an experienced radio/TV technician for help.

To satisfy FCC RF Exposure requirements for mobile and base station transmission devices, a separation distance of 20 cm or more should be maintained between the antenna of this device and persons during operation. To ensure compliance, operation at closer than this distance is not recommended. The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.


User's Manual

If the Wireless Unit is used in a portable application (antenna is less than 20 cm from persons during operation), the integrator is responsible for performing Specific Absorption Rate (SAR) testing in accordance with FCC rules 2.1091

1.3.2 Canada IC Approval

This device contains IC ID: 7693A-24J40MA

This device has been certified for use in Canada under Industry Canada (IC) Radio Standards Specification (RSS) RSS-

210 and RSS-Gen.

1.3.3 European Approval

Radiated Emissions

Test standards ETSI EN 301 489-1:2008 and ETSI EN 301 489-17:2008:

Radiated Emissions

Electro-Static Discharge

Radiated RF Susceptibility

1.4 Battery Safety Considerations

The Wireless 3-Space Sensor contains a rechargeable lithium-polymer battery. Lithium-polymer batteries have high energy densities and can be dangerous if not used and cared for properly. The Wireless 3-space Sensor has been designed to include multiple levels of battery safety assurance. The Wireless 3-Space Sensor circuitry includes smart charging circuitry with thermal management to prevent over-charging the battery. The battery pack itself also includes protection circuitry to prevent over-charge, over-voltage, over-current, and over-discharge conditions.

Most battery issues arise from improper handling of batteries, and particularly from the continued use of damaged batteries.

As with any lithium-polymer battery-powered device, the following should be observed:

Don’t disassemble, crush, puncture, shred, or otherwise attempt to change the form of your battery.

Don't attempt to change or modify the battery yourself. Contact YEI technical support for battery replacement or battery repair.

Don’t let the mobile device or battery come in contact with water.

Don’t allow the battery to touch metal objects.

Don’t place the sensor unit near a heat source. Excessive heat can damage the sensor unit or the battery. High temperatures can cause the battery to swell, leak, or malfunction.

Don’t dry a wet or damp sensor unit with an appliance or heat source, such as a hair dryer or microwave oven.

Don't drop the sensor unit. Dropping, especially on a hard surface, can potentially cause damage to the sensor unit or the battery.

Discontinue use immediately and contact YEI technical support if the battery or sensor unit produce odors, emit smoke, exhibit swelling, produce excess heat, exhibit leaking.

Dispose of Lithium-polymer batteries properly in accordance with local, state , and federal guidelines.
