2.3 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 top two pins, marked NZ, to set the frequency
range to 921-928 MHz for New Zealand.

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

• 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.
Caution: When pressing the Reset button, make sure you don’t also touch

the frequency band selection pins. Touching the frequency band selection
pins while pressing the Reset button can inadvertently set the transmitter
to the wrong frequency band.
