Warnings
This device complies with Part 15 of the FCC rules, Operation of this device is subject to the
following conditions: 1. This device may not cause harmful interference. 2. This device must
accept any interference, including interference that may cause undesired operation.
Installation:
The DCHT-2500 transmitter consists of a transmitter box and 25 feet of hose.To install,connect
the hose to the stem on the transmitter box, then lay the hose across the driveway. Mount
the transmitter box on a tree or wooden post at least three feet off the ground (see figure
1). Avoid using steel posts as this may interfere with the radio signal.The maximum range of
the system is about 2500 feet, however, obstructions such as hills, trees and metal siding can
reduce the range.
Connect a 9-volt alkaline battery to the transmitter. The battery should last about 6 to 12
months under normal conditions. Once the battery is connected, the system will need a few
seconds to warm up.After this time the transmitter will detect vehicles driving over the hose.
Make sure that there are no kinks in the hose, as this may keep the transmitter from detecting.
When the transmitter detects a car, it will send a signal to the receiver, which will sound one of
four different tones (Classical,Westminster Chime, Ding Dong, or Whistle) for a few seconds.

Operation: (Always test unit prior to installation)
The control box is powered by one 9-volt battery.
Coding the transmitter:
Note: The transmitters and receivers are preset
at the factory. DO NOT change settings, unless
changing the tune or experiencing false signals.
1.
Open the transmitter box.The first thing you will see is
the air switch (Figure 2). Directly below the air switch
is the transmitter’s radio (Figure 3).
2. Locate the dip switches on the radio (2)(3).
3. Switches 1-8 are for the frequency setting
(256
combinations). If needed, set switches 1-8 (2) to
match the eight switches in the receiver.
4. Switches 9 and 10 (3) are for the channel setting on
the transmitter. Use these to set the tone you prefer.
The four channels are listed in the table on page 5
.

Table to select tones:
Coding the receiver:
1. Open the receiver case by inserting a small
screwdriver into one of the pry notches on the
side of the case.(refer to receiver manual)
2. Gently lift off the front cover.
3. Locate the eight dip switches on the receiver and
make sure they are set identically to dip switches
1-8 on the transmitter.
Note: If more than one transmitter is
used with the receiver, the first eight dip
switches of all transmitters must match
the eight dip switches of the receiver.
Note: Whenever a change is made to any
jumper or the dip switches, the receiver
must be turned OFF and then back ON
to operate properly.
Frequency: 433.92 MHz
Operating range: -30˚F to 120˚F
Battery life: 6-12 months
LOW BATTERY ALERT: If the receiver
sounds a second alert 30 seconds after
the rst alert, provided nothing trips the
transmitter again, the 9-volt battery in
the transmitter should be changed.

•฀Keep฀the฀transmitter฀away฀from฀large฀metal฀objects฀that฀may฀interfere฀with฀the฀radio฀signal.
•฀Adjust฀the฀screw฀on฀the฀air฀switch฀in฀the฀transmitter฀(Figure฀2)฀(1)฀by฀turning฀it฀clockwise.฀
This will increase the sensitivity.
•฀If฀the฀contacts฀are฀touching,฀the฀system฀will฀not฀work.If the transmitter is giving false signals, try one of these:
•฀Adjust฀the฀screw฀on฀the฀air฀switch฀in฀the฀transmitter฀(Figure฀2)฀(1)฀by฀turning฀it฀counter-
clockwise.This will decrease sensitivity.
•฀Set฀the฀transmitter฀and฀receiver฀to฀a฀different฀code฀setting.฀Refer฀to฀instructions฀on฀pages฀
