Regulatory Information
Notice to Users:
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.
FCC Statement:
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. Changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate the equipment. The antenna(s) used for this
transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
CE Statement:
This equipment has been tested and found to comply with the limits of the European Council Directive on the
approximation of the law of the member states relating to electromagnetic compatibility (89/336/EEC) according to
EN 55022 Class B.
Industry Canada Equipment Notice:
Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device
must accept any interference, including interference that may cause undesired operation of the device.
The Industry Canada certification identifies certified equipment. This certification means that the equipment meets
certain telecommunications network protective, operational and safety requirements as prescribed in the
appropriate Terminal Equipment Technical Document(s). The Department does not guarantee the equipment will
operate to the user's satisfaction. Before installing this equipment, users should ensure that it is permissible to be
connected to the facilities of the local telecommunications company. The equipment must also be installed using an
acceptable method of connection. The customer should be aware that compliance with the above conditions may
not prevent degradation of service in some situations. Repairs to certified equipment should be coordinated by a
representative designated by the supplier. Any repairs or alterations made by the user to this equipment, or
equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the
equipment.
Users should ensure, for their own protection, that the electrical ground connectors of the power utility, telephone
lines and internal metallic water pipe system, if present, are connected together. This presentation may be
particularly important in rural areas.
Caution: Users should not attempt to make such connections themselves, but should contact the appropriate
electric inspection authority or electrician, as appropriate.

1. Unpacking
a. Each Node is shipped with…
i. Two pairs Lithium AA batteries.
ii. One pair double sided mounting tape
iii. Installation Manual
Check the contents of the package. Contact SynapSense if there
are any parts missing.

2. Operation
The SynapNet Node is designed to work in conjunction with a
SynapNet Gateway device and the SynapSoft console. Please be
sure you have correctly configured SynapSoft on the gateway
computer prior to continuing.
SynapNet nodes can be added to an existing SynapSense Wireless
Network (driven by a SynapNet Gateway) or be used to form a
network. Note that battery life will be compromised if the
SynapNet Node is not in range of an active gateway device or
other SynapNet Node which is part of a running network.
Installing batteries:
a. Remove the Lithium AA batteries from the packaging
material.
b. Unsnap the battery cover by inserting a small
screwdriver in one of the battery release slots.
c. Insert the batteries into the marked positions in the
orientation displayed on the device.
d. The device will blink an alternating green/red for five
seconds when the batteries are correctly inserted and
the power switch is turned on.
e. Replace cover on the device.
f. The device will attempt to join any available
SynapSense Wireless Sensor Networks. For more
information on network formation, node placement,
please see the SynapSense Wireless Network User
Guide.
External Sensor Operation:
The SynapNet node allows for the connection of up to 6
external temperature sensors. Please be sure to remove all

batteries from the device prior to working on the SynapNet
Node. These will be provided preassembled by SynapSense.
Consult the guide provided with the sensor interface device for
specific instructions on mounting the external temperature
sensors.
NOTE: Use of the equipment with any sensor interface device
cable other than the one provided is prohibited. Use of
unauthorized equipment may void the warrantee and void the
regulatory certification of the equipment.
Troubleshooting and Diagnostics:
1. No lights appear when batteries are inserted
Please be sure the battery orientation is correct and that
the batteries are fresh and charged.
2. A solid red light appears
The battery on the device has fallen below allowable
operating level and the device has suspended its self to
prevent network problems.
3. The red light flashes briefly every 5 seconds
The node is currently not associated with an active
wireless sensor network. Make sure the node is in range
of either an active gateway device or another networkassociated SynapNet Node. A node may take up to 20
minutes to fully join an existing network.
Nodes may fall out of an active network if their signal
strength is weak. Consider topology changes such as the

addition of repeaters of the movement of other nodes in
order to improve signal conditions. For more information,
see the SynapSense Wireless Sensor Network User’s
Guide.
4. The node appears to have stopped sending on the network
Check for the flashing red light (above) to see if the node
has somehow fallen out of the network.
The node can be reset without the removal of the battery
comportment by the use of a magnetic reset tool, or any
medium powered magnet. While watching the diagnostic
light area, move the magnet along the long edge opposite
the external sensor ports. The diagnostic lights will light
and flash when the node has successfully reset.
