2.6 Transmit timing
The setup of the transmission timing allows avoiding possible collisions with data packages
of other EnOcean transmitters as well as disturbances from the environment. With each
transmission cycle, 3 identical subtelegrams are transmitted within 40 ms. The transmis-
sion of a subtelegram lasts approximately 0.7 ms. The delay between the three transmis-
sion bursts is affected at random.

3 APPLICATIONS INFORMATION
3.1 Transmission range
The main factors that influence the system transmission range are type and location of the
antennas of the receiver and the transmitter, type of terrain and degree of obstruction of
the link path, sources of interference affecting the receiver, and “dead” spots caused by
signal reflections from nearby conductive objects. Since the expected transmission range
strongly depends on this system conditions, range tests should categorically be performed
before notification of a particular range that will be attainable by a certain application.
The following figures for expected transmission range are considered by using a PTM, a
STM or a TCM radio transmitter device and the TCM radio receiver device with preinstalled
whip antenna and may be used as a rough guide only:
Line-of-sight connections: Typically 30 m range in corridors, up to 100 m in halls
Plasterboard walls / dry wood: Typically 30 m range, through max. 5 walls
Ferroconcrete walls / ceilings: Typically 10 m range, through max. 1 ceiling
Fire-safety walls, elevator shafts, staircases and supply areas should be considered as
screening.
The angle at which the transmitted signal hits the wall is very important. The effective wall
thickness – and with it the signal attenuation – varies according to this angle. Signals
should be transmitted as directly as possible through the wall. Wall niches should be
avoided. Other factors restricting transmission range:
Switch mounted on metal surfaces (up to 30% loss of transmission range)
Hollow lightweight walls filled with insulating wool on metal foil
False ceilings with panels of metal or carbon fiber
Lead glass or glass with metal coating, steel furniture
The distance between EnOcean receivers and other transmitting devices such as comput-
ers, audio and video equipment that also emit high-frequency signals should be at least 0.5
m.
A summarized application note to determine the transmission range within buildings is
available as download from www.enocean.com.
PTM 335 / PTM 335C is optimized for use in wooden door frames.
(Performance was tested with wood adjacent to simulated plastic housing around PTM 335)
Radio performance may vary due to proximity of other material in installation (e.g. plastic).
Any metal parts close to PTM 335/PTM 335C will degrade performance or at least change
radiation pattern.

4 AGENCY CERTIFICATIONS (after release for series production)
The modules have been tested to fulfil the approval requirements for CE (PTM 335) and
FCC/IC (PTM 335C) based on the built-in firmware.
4.1 CE approval
The module bears the EC conformity marking CE and conforms to the R&TTE EU-directive
on radio equipment. The assembly conforms to the European and national requirements of
electromagnetic compatibility. The conformity has been proven and the according docu-
mentation has been deposited at EnOcean. The modules can be operated without notifica-
tion and free of charge in the area of the European Union, and in Switzerland. The following
provisos apply:
EnOcean RF modules must not be modified or used outside their specification
limits.
EnOcean RF modules may only be used to transfer digital or digitized data.
Analog speech and/or music are not permitted.
The final product incorporating EnOcean RF modules must itself meet the es-
sential requirement of the R&TTE Directive and a CE marking must be affixed
on the final product and on the sales packaging each. Operating instructions
containing a Declaration of Conformity has to be attached.
If the transmitter is used according to the regulations of the 868.3 MHz band,
a so-called “Duty Cycle” of 1% per hour must not be exceeded. Permanent
transmitters such as radio earphones are not allowed.
USER MANUAL V0.6
PTM 335 / 335C
4.2 FCC (United States) Certification
PTM 335C LIMITED MODULAR APPROVAL
This is an RF module approved for Limited Modular use operating as an intentional trans-
mitting device with respect to 47 CFR 15.231(a-c) and is limited to OEM installation. The
module is optimized to operate using small amounts of energy, and may be powered by a
battery. The module transmits short radio packets comprised of control signals, (in some
cases the control signal may be accompanied with data) such as those used with alarm
systems, door openers, remote switches, and the like. The module does not support con-
tinuous streaming of voice, video, or any other forms of streaming data; it sends only short
packets containing control signals and possibly data. The module is designed to comply
with, has been tested according to 15.231(a-c), and has been found to comply with each
requirement. Thus, a finished device containing the PTM 335C radio module can be oper-
ated in the United States without additional Part 15 FCC approval (approval(s) for uninten-
tional radiators may be required for the OEM’s finished product), under EnOcean’s FCC ID
number. This greatly simplifies and shortens the design cycle and development costs for
OEM integrators. The module can be triggered manually or automatically, which cases are
described below.
Manual Activation
The radio module can be configured to transmit a short packetized control signal if trig-
gered manually. The module can be triggered, by pressing a switch, for example.
The packet contains one (or more) control signals that is(are) intended to control some-
thing at the receiving end. The packet may also contain data. Depending on how much en-
ergy is available from the energy source, subsequent manual triggers can initiate the
transmission of additional control signals. This may be necessary if prior packet(s) was
(were) lost to fading or interference. Subsequent triggers can also be initiated as a precau-
tion if any doubt exists that the first packet didn’t arrive at the receiver. Each packet that is
transmitted, regardless of whether it was the first one or a subsequent one, will only be
transmitted if enough energy is available from the energy source.
OEM Requirements
In order to use EnOcean’s FCC ID number, the OEM must ensure that the following condi-
tions are met:
End users of products, which contain the module, must not have the ability to alter the
firmware that governs the operation of the module. The agency grant is valid only when
the module is incorporated into a final product by OEM integrators.
The end-user must not be provided with instructions to remove, adjust or install the
module.
The Original Equipment Manufacturer (OEM) must ensure that FCC labeling require-
ments are met. This includes a clearly visible label on the outside of the final product.
Attaching a label to a removable portion of the final product, such as a battery cover, is
not permitted. The label must include the following text:
