SETTING UP THE SIGN BOARD  

You can place the sign board on a flat surface or mount it on a wall.  If  
you plan to connect the display to the security system, choose a location  
where people can see the alarm message, such as in a window.

CAUTION:  This sign board is only designed for indoor-use.  For reliable  
          operation, install the sign board where it is not exposed to  
          water or extreme heat  

Placing the Sign Board on a Table/Stand  

Set the sign board on a stable, flat surface (such as a table).  To adjust
the sign board's angle, use a Phillips screwdriver to loosen the screws on
the sign board's back plate.  Adjust the back plate for the desired viewing
angle.  Then, tighten the screws.

Mounting the Sign Board on a Wall  

Follow these steps to mount the sign board on the wall.  

1.  Using a Phillips screwdriver, remove the hinge screws on the back  
    plate.  

2.  Use the back plate as a guide and drill two 1/16-inch holes in the  
    wall so that the holes are 5 7/8 inches apart (horizontally).  

3.  Remove the supplied screws from their shipping package and thread them   
    into the holes in the wall, letting them extend 1/4 inch from the  
    wall.  

4.  Align the back plate's keyhole slots with the screws in the wall.   
    Then, press the back plate against the wall and slide it down onto  
    the screws.  Tighten the screws.  

5.  Attach the sign board to the back plate and replace the washers and  
    screws as shown.  

6.  Adjust the sign board to the desired angle.  Then, tighten the hinge  
    screws.  

CONNECTING POWER  

You can only operate the sign board from a standard household outlet.  We  
recommend that you also install batteries for back-up power for memory.  

AC Power

Plug the supplied AC adapter into the sign board's 10V jack.  Plug the  
other end into any standard AC outlet.  

CAUTION:  You must use an AC adapter that supplies 10 volts and delivers  
          at least 1 amp.  Its center tip must be set to negative, and its  
          plug must correctly fit the sign board's 10V jack.  Using an   
          adapter that does not meet these specifications could seriously   
          damage the sign board or the adapter.  

Memory Back-Up Battery Power  

The sign board uses two AAA batteries for back-up battery power for  
memory.  For long battery life, we recommend alkaline batteries, such as   
Radio Shack's Cat. No. 23-555.  Follow these steps to install the backup  
batteries.

NOTE:  When you replace the batteries, keep the AC adapter plugged into
       the sign board and an AC outlet.  Otherwise, the stored messages
       are lost.

1.  Open the keyboard cover.  

2.  Slide the battery compartment door to the right and lift it off.  

3.  Insert the two batteries, as indicated by the polarity symbols (+ and  
    -) marked inside the compartment.  

4.  Replace the battery compartment door and close the keyboard cover.  

To test memory back-up battery power, turn on the sign board.  Press  
OFF/END.  Then, press BATT.  If the indicator does not light, replace the  
batteries.

Power Failures

The sign board's memory holds the messages until you delete them or power 
fails for an extended period of time.  The power source that fails and the
length of time it fails determines whether the sign board keeps the
messages in memory.

If AC and battery power fail, the sign board keeps messages in memory for
10 seconds.  To keep the messages, AC or battery power must resume within
the 10 seconds.  When AC power resumes, the sign board performs its self
test.  If messages were saved and you were editing or entering a message
when power failed, the sign board detects an error during its test and
shows PLEASE RE-EDIT INCOMPLETE MESSAGE # ____  BY PRESSING "EDIT/DELETE"
KEY.  If this appears, follow the steps in "Editing a Stored Message."

If the sign board has no power for more than 10 seconds, all messages are  
lost and the sign board defaults to the preprogrammed messages.  

CONNECTING TO A SECURITY SYSTEM  

You can connect the sign board to the security system so that when an  
intruder triggers the alarm, the sign board shows an alarm message to  
security personnel or anyone passing by your store or home.  Follow these  
steps to connect the sign board to a security system.  

1.  Plug the supplied cord into the ALARM jack on the side of the sign  
    board.  

2.  Connect the cord's two wires to a pair of normally open terminals on  
    the security system.  These terminals must not supply power.
