Car Alarms: 5000RS remote, transmitter button, car operation

Question
I wanted to know what the little button on the side of the 4 button remote is used for?

Answer
Button 5 is the Page Shift button.
Each time the Shift Button is pressed,
the LED on the transmitter will
illuminate and the transmitter functions
will shift to the next page,
allowing access to another set of
features. Once shifted to another page
(there are 4 pages total), for use in features programing.

The transmitter will remain on that page
for 10 seconds or until a button is pressed, then return to page 1. Each time a transmitter button is pressed
and held, the LED will flash a number of times
to indicate from which page it is transmitting.

Under normally operation, only pages 1 and 2 are used.
Pages 3 and 4 are usually used for Two Car Operation
or optional expansion modules.

Disregard if this does not apply to you.
