Annex A
Health Care Pendant / Pillow Speaker Operation
The Philips 20FT3310 Institutional Television product can be used in hospitals and other medical facilities. It is
compatible with a type of device known as a “pillow speaker” or “pendant control”. This device contains a
built-in speaker for bedside audio, while also providing television power, channel, and volume control functions,
all by means of a three-conductor cable. Examples of two such devices are described herein. The following
products are manufactured by Curbell Industries (www.curbell.com), Orchard Park, NY.
The “analog” version of the pillow speaker, as it is sometimes
referred to, provides a built-in speaker, a volume control, and one
dual-purpose button that both selects the TV channel, and powers
the television on and off.
If the television is in the standby state (power off), a single press
of the channel / power button will turn the unit on.
When the television is on, each press of the button increments the
currently-tuned channel.
If the television is on, it will power off when the the channel /
power button remains depressed for four successive channel increments
(the television will power off
after
the fourth channel increment).
NOTE: Analog-style controls tend to exhibit a relatively slow
response time to channel commands
. This is normal, and is not
indicative of a system problem.
One example of a so-called “digital” version of the pillow speaker
provides a built-in speaker, a volume control, and dedicated buttons
that perform the following functions, as indicated.
• Power on/off
• Channel up
• Channel down
• Closed-caption
• Channel guide
