2 Installation and Startup

2.1 Install/Replace the Battery

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

transmitter.

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

the transmitter’s most recent programming will be restored upon
initialization.

2.2 Select the Frequency Band

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.

2. Press the Reset button to complete configuration.

2.3 Attach the Analog Sensors and Select Output

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

Note: 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.

2. 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.
