2 - HINTS ON SYSTEM USE AND MAINTENANCE
This section covers some important tips on how to use and maintain your Horizon system. After you
understand it completely, you should review this information, as well as that contained in section 1, with
everyone who will use or maintain this system. Your installing dealer should also give you a single page of
"User Instructions" that you can copy and give to each person. This training will make sure that user problems
are minimized, which in turn will make your life easier. Even if this seems clear and uncomplicated to you,
experience suggests that untrained users will initially have troubles.
VISITOR ENTRY
1. When an occupant is allowing entry, neither party should hang-up until the occupant has pressed the
appropriate key on his/her telephone.
2. The Horizon system has a feature that you (or anyone else you choose to tell about this feature) may
use to initiate communication with the system. Dial the telephone number of the line to which the
Horizon is connected and when it answers, press the "#" key on your telephone. This will establish
two-way communications using the Horizon's speaker and microphone, but will not allow you to grant
entry. The call will time out just like a call placed from the Horizon.
CODE ENTRY
1. If someone enters part of their entry code incorrectly, they can clear the incorrect entry by pressing
the " " key once. They must start over at the beginning of the code.
2. When an incorrect entry code is made on the keypad, the system will normally display an "INVALID
CODE - PLEASE WAIT" message for 3 seconds and then say "NOW TRY AGAIN". However, if this
incorrect entry code causes the system to meet your "strikes-and-out" limit, the first message will say
"INVALID ENTRY" not "INVALID CODE" and the "NOW TRY AGAIN" message will not appear.
Moreover, for the next 3 minutes the system will respond "SYSTEM IN USE" anytime someone tries
to enter an entry code at the keypad.
SYSTEM MAINTENANCE
1. The window that protects your display in your system may have been treated with a special coating
that essentially eliminates glare and makes it much easier to read the display (this is an option -
consult your dealer to inquire if this has been purchased with your system). However, accumulated
dirt or dust on the window or display can , over time, significantly reduce the readability of the display.
Consequently, you should make sure that the window is kept clean, both on the outside and the
inside. To clean the outside, use a soft, lint-free cloth and a mild solution of soap and water. DO
NOT USE HARSH CLEANERS OR YOU WILL SCRATCH THE WINDOW.
