acclimate to the new environment after manufacturing, and could exhibit an
accuracy variant of +/-2% during that time.

6 Television and Radio Interference

This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference
in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

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 on the bottom of the
transmitter; separate the housing.

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

4. Install the new battery.

5. Press the Reset button to initialize the transmitter.

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 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 EN1721 to
the wrong frequency band.
