 Figure 1  EN1702 Components

Pry the top lip of the mounting bracket up, and lift the bracket off of the transmitter.

Use your thumb to depress the housing release tab; separate the housing.

If replacing a battery, use the hole in the back of the housing to push the old 
battery out of the battery holder.

Install the new battery.

Press the Reset button to initialize the transmitter. If replacing a battery, the 
transmitter’s most recent programming will be restored upon initialization.

EchoStream products are able to use a range of radio frequencies, and must be 
configured for your geographic area. To configure the transmitter:
1.

Place a selection jumper on the appropriate frequency band selection pins.

•

Place the jumper on the left two pins, marked AU, to set the frequency range to 
915-928 MHz for Australia.

•

Place the jumper on the right two pins, marked NZ, to set the frequency range to 
921-928 MHz for New Zealand.

•

Leave the jumper off the pins to set the frequency range to 902-928 MHz for 
North America.

Press the Reset button to complete configuration.

To use the EN1702, you must connect the analog sensor(s) to one or both of the 
terminal blocks. To connect the analog sensors:

The analog sensor cable length must not exceed three feet.

Place a selection jumper on the appropriate sensor output selection pins (Fig. 
1C).

•

Place the jumper on the bottom two pins, marked 4-20mA, to select a sensor 
output of 4-20mA.

•

Place the jumper on the middle, marked 0-10V, two pins, to select a sensor 
range of 0-10V.

•

Place the jumper on the top two pins, marked 0-5V, to select a sensor range of 
0-5V.

Referring to Figure 2, use a small screwdriver to attach the external sensor(s) 
wiring leads to the appropriate terminal blocks.

If the battery has been installed, press the Reset button to complete the 
procedure.

 Figure 2  EN1702 External Sensor Wiring

EN1702 transmitters are programmed at the factory. It is not usually necessary to 
reprogram EN1702 series transmitters. If you want to reprogram the transmitter, 
parameters can be changed using the programming header.

Attach the mounting bracket to the wall, using the included hardware.

There are two mounting holes for standard installation. An optional third mounting hole 
is located under the battery. Use the third mounting hole to secure the housing to the 
bracket.

Hook the bottom of the transmitter into the bracket’s bottom catch, and press the 
transmitter into the bracket so that the bracket’s top lip snaps into place.
