CONTENTION CONSIDERATIONS
It is important to understand that only one transmitter at a time can be activated
within a reception area. While the transmitted signal consists of encoded digital
data, only one carrier of any particular frequency can occupy airspace without
contention at any given time. If two transmitters are activated in the same area
at the same time, then the signals will interfere with each other and the decoder
will not see a valid transmission, so it will not take any action.
BATTERY REPLACEMENT
The remote unit utilizes a standard CR2032 lithium
button cell. In normal use, it will provide 1 to 2 years
of operation. To replace the battery, remove the
screw in the middle of the back cover. Once the unit
is open, remove the battery by depressing the
COMPLIANCE REQUIREMENTS
The CMD-HHTX-*** has been pre-certified by Linx for FCC Part 15 compliance
when used with an appropriate function module in keeping with the applications
allowed under section 15.231.
LABELING / INSTRUCTION REQUIREMENTS
The CMD-HHTX-*** Handheld transmitter has already been labeled in
accordance with FCC regulations in effect as of the date of this document. No
further labeling of the unit is needed; however, it is necessary to include the
following statement in the end product’s instruction manual or insert card for FCC
compliance.
release finger on the battery holder as shown.
Replace it with the same type of battery while
observing the polarity shown in the adjacent figure.
There may be the risk of explosion if the battery is
replaced by the wrong type. Replace it with the same
type of battery while observing the polarity shown in
the adjacent figure.

INSTRUCTION TO THE USER
This device complies with Part 15 of the FCC Rules.
Operation of this device 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.
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.
This equipment has been certified to comply with the limits for a Class B
computing device, pursuant to FCC Rules. In order to maintain compliance with
FCC regulations, shielded cables must be used with this equipment. Operation
with non-approved equipment or unshielded cables is likely to result in
interference to radio and TV reception. The user is cautioned that changes and
modifications made to the equipment without the approval of manufacturer
could void the user’s authority to operate this equipment.
