INSTALLATION PROCEDURE
When installing the Visual-Pager System, the following
procedures should be followed.
IMPORTANT PRE-INSTALLATION INSTRUCTIONS
Before permanent installation, we recommend that
you test your entire system in one room on a table or
floor. This will be of great benefit in troubleshooting
if you should have any problem after installing the
system.
STEP 1: Test 1904
Connect the wall mount transformer to the Model
1904 Keypad at the 18-24 VAC connector. Turn
power "ON" and enter a number, If the number
appears on the Keypad display, the Keypad is working.

STEP 2: Test 1904 & Display
Connect the wall mount transformer to the dis—
play at the 18-24 VAC connector. Type numbers
into the keypad and they should appear on the
remote display.
Permanent
Installation
FIRST: Select location for Display
and Keypad.
In almost all Iowpower unlisenend wireless sys-
tems there is a chance that some places in a particular
building may be "dead spots". (Places were the dis-
play will not receive the signal from the keypad.)
These ”dead spots" however may only be a few
inches apart. Therefore moving a display 6 inches in
any direction could well make the difference between
a working and nonworking system. To select the
place were the system will best work for you Place the
keypad in your most ideal location. Lean it aginst
someting so the antenna is vertical like the display.
This will establish the best signal Iink.Type several
numbers in to the keypadlike 10, 20, 30. Next take
the display to its most Ideal location. If the numbers
appear on the display and rotate through every 3
seconds then everything is fine and you may proceed
with the permant installation. If however the system
is not working try moving the display or kepad to
slightly different locations and repeat the test until
you find a suitable setup for the system.
CAUTION
24 VOLTS A.C. IS PRESENT UNDER THE
SMALLSLIDE—ON COVER. TURN POWER OFF
TO PREVENT DAMAGE TO 1904 UNIT.
INSTALLATION PROCEDURE
(conti nued)
SECOND: Install The 1904 Keypad
Select a location that is handy but not in the way
The Model 1904 Keypad should be mounted on the
wall with the antenna pointing up. Locate the Keypad
so that the cord from the wall-mount transformerwill
not be accessible to children or present a safety
hazard. The installation location must bewithin 5 feet
of an AC power outlet so that the cord may reach the
Keypad.
Place the Keypad in the enclosed plastic wall
mounting bracket, if needed. Place at the desired
mounting location and mark the position. Slide the
Keypad out of its mountinghracket and attach bracket
using screws supplied. Once screws are screwed in
flush with back of bracket, slide Keypad into bracket.
The Keypad is easily removed, if necessary.
Installthe Keypad andconnectto AC powerl Test
for operation by entering a number and observing
this number in the built~in display of the Keypad.
This verifies that the keypad is working.
THIRD: Install the Remote Display
The Remore Display will have optimum visiblity
when mounted within five to 10 feet of the stage floor.
This will keep the display in the proper field of view
for the observer.
Type several numbers in to the keypadlike 10, 20,
30. Then hold the remote display in position and
watches the numbers. If the numbers appear on the
display and rotate through every 3 seconds then
everything is fine and you may proceed with the
permant installation The Remote Display may he
hung on a screw anchored in the wall.

OPERATION
Instructions for Use
The Model 1904 Keypad has its own built-in, easye
to—read display so that you can see what numbers are
being entered as well as what numbers are being
shown on the Remote Display.
Normal Mode
While in normal mode, the Keypad display will
show the same numbers as the Remote Display.
Enter Mode
When a number button is pressed, the Keypad will
go into enter mode and the "ENTER" light will flash.
While in enter mode, the number to be paged will be
shown only on the Keypad display. Continue to press
number buttons until the complete number to be
paged is shown. Then press "ENTER" to display the
paging number on the 1940 Remote Display. When
"ENTER“ is pressed, the Keypad will leave the enter
mode and the new number will be placed in sequence
with any other numbers displayed on the Remote
Display. If you make an error while entering a num—
ber, press "DELETE."
Delete Mode
To delete a paging number, press "DELETE"
when that number appears on the display. The next
available number will be displayed immediately. You
may also delete a number at any time by typing the
number and pressing "DELETE."
Multiple Paging
The Keypad will store up to 30 four—digit numbers
and display them sequentially until the operator de-
letes them. These numbers may be entered one at a
time using the instructions above.
Multiple Outputs
You may have an unllimited number of Remote
Displays connected to your system.
Multiple Keypads - Model 1904
You may cascade up to 32 Model 1904 Keypads by
wiring the keypads together. Use a common cable
connected to the “Signal Out" output from each
Keypad. Numbers entered from each Keypad will
automatically be combined and displayed in sequence
with all the numbers entered from all Keypads. Each
Keypad will display all numbers entered from itself as
well as all numbers entered from all other Keypads at
the same time they are displayed on the Remote
Display(s). A number may be deleted by pressing
"DELETE" on any Keypad when that number ap-
pears in the Keypad Display, or by typing in the
number then pressing "DELETE."
Power Connection
Connect the wall mount transformer to an AC
outlet and connect the power plugto the connector on
the top of the Keypad marked "18-24 VAC ." It is
recommended that you turn the power off using the
“ON/OFF" switch on the Keypad when not in use.
This will greatly prolong the life of the system.
Fuse
The Model 1904 Keypad contains a fuse inside the
case under the small slide-on cover. When replacing
the fuse, be sure to disconnect power from the AC
wall outlet. Replace only with the fuse size stated in
