For higher security applications, the HS Series encoder has the option to set a
Personal Identification Number (PIN) to control access to the encoder. This PIN
is a four-button sequence of the eight available buttons which must be entered
before the transmitter will send any commands. It will need to be re-entered after
fifteen minutes of inactivity. If no PIN is created, then the transmitter will activate
as soon as a button is pressed.
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.
The transmitter uses a standard CR2032 lithium
button cell. In normal use, it will provide 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. 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
