KP21R Remote Control Features
when the button is pressed must be restarted.
I Extensive use of the programming, learning and configuration
functions of the remote may consume significantly more
battery power than normal remote operation. While the
batteries should last for four to six months in normal operation,
you may find that they need to be changed sooner, after
the remote is programmed for the first time.
I When the batteries approach a level below which the remote
control will not function, the remote’s LCD screen will display
a LOW BATTERY warning as shown in
Figure 153. We
strongly recommend replacing the batteries as soon as this
message appears, to avoid the loss of programming and con-
figuration settings. These settings are not lost when the bat-
teries are changed quickly.
Figure 153.
I The remote has a built-in backlight that may be activated by
pressing the
Light Button . This button is made from
a special “glow” material so that it is easier to find in dark
rooms. This glow feature does not consume any electricity,
but the glow will fade when the remote is kept in a dark
location for an extended period of time. The “glow” feature
may be restored by placing the remote in normal room light
for a few hours.
I The remote’s backlighting will remain lit for approximately
5 seconds after the
Light Button is pressed, and it will
stay lit for another 5 seconds if any key is pressed while the
backlight is on. You may keep the backlighting on by holding
the Light button, but extensive use of the backlighting will
reduce battery life.
I The LCD will remain on for 10 seconds after a key is pressed,
and then turn off to conserve battery life.
I When any button is held for more than 30 seconds, the LCD
will turn off and the remote will stop transmitting the codes,
to conserve battery life.
