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 provides 1 to 2 years of
operation. To replace the battery, remove the access
cover by pressing firmly on the label area and sliding it
off. Once the unit is open, remove the battery by sliding
it from beneath the holder. Replace it with the same type
of battery while observing the polarity shown in Figure 6.
There may be the risk of explosion if the battery is
replaced by the wrong type.
