. INTRODUCTION
. INTRODUCTION
The WT-104 is a miniature, 4-channel hand-held wireless trans-
mitter, designed to operate with Visonic Ltd. wireless receivers of
the WR-200 and WR-300 series.
Transmission is activated by pressing any one of the 4 recessed
buttons on the unit. Transmitted data consists of a system code
(see Para. 3.2 below) and one of four different channel codes that
activates the corresponding output of the target receiver.
The transmitter is powered by a 12 volt alkaline battery. An LED
lights during transmission, indicating the battery voltage condition. If
the LED does not light during transmission, the battery must be
replaced immediately.
All WT-104 units are supplied with a key-holder installed. A neck
chain is also included in the package, to permit the unit to be
worn as a pendant transmitter.

3.1 Battery Installation
A. Open the case by removing the screw from the back cover.
B. Insert the 12-volt alkaline battery (Duracell MN-21 or Golden
Power GP-23A or equivalent) between the battery clips, so
that the (+) and (–) markings on the battery are in the same
direction as the markings on the P.C. board (close to each
battery clip - see Figure 1). Check that the battery is held
securely by the battery clips.
C. Gently press one of the pushbutton switches and verify that
the LED lights, indicating good battery condition.
3.2 Coding
A. All WT-104 units have an
8-key
DIP
switch
block
(marked 1 to 8). Each switch
may be set to ON or OFF
position, to create a unique
digital system code - see
Figures 1 and 2.
B. Use a ball point pen to set each of the switches to match the
code setting of the companion receiver.
CAUTION: The code combination 2, 4, 5, 6, 7 ON / 1, 3, 8
OFF is a factory test code which must not be used. Also avoid
codes which are often used: all keys ON, all keys OFF or
alternating ON/OFF settings.
