2 Survey Receiver Overview
The EN4016SK survey receiver provides a portable, easy-to-use means to
conduct site surveys to determine optimal hardware installation locations,
as well as to perform diagnostics on existing EchoStream sites.
2.1 Measuring Signal Strength
The survey receiver measures the signal strength of high-power repeater
and end-device messages to help optimize your EchoStream system,
providing two signal strength measurements: signal level and signal
margin.
Signal level: The signal level is the measurement of the overall decibel
level of the message.
Signal margin: The signal margin is the measurement of the decibel level of
the message, minus the decibel level of any interfering signals. Inovonics
Wireless equipment should be placed within a facility such that all end-
devices produce signal margin readings of at least 4 decibels.
Both the signal level and signal margin are measured in decibels. Because
signal strength and signal margin are measured on a logarithmic scale, the
difference between a decibel level of 3 (Weak) and a decibel level of 4
(Good) is a much larger difference than it would be on a linear scale.

2.3 What’s in the Carton
• An EN4016SK EchoStream survey receiver
You will also need:
• An EN1210SK and/or EN1223SK survey transmitter, sold separately.
• A set of four fresh AA alkaline batteries, or four fully-charged AA NiMH
rechargeable batteries, for the receiver
You may also want:
• Headphones with a 3.5 mm plug
• A battery charger, if using rechargeable batteries
- Inovonics Wireless recommends either Rayovac PS5/PS6 or
Energizer CH30MNCP-4 batteries
3 Startup
3.1 Configure Survey Transmitters
Note:
The survey transmitters are designed for use with the survey
receiver only. Survey transmitters should not be used to perform range
tests with any EchoStream receivers other than the EN4016SK survey
receiver.
EchoStream devices are able to use a range of radio frequencies, and must
be configured for your geographic area. Survey transmitters ship with a
default frequency range of 902-928 MHz for use in North America. If you
are using the survey kit in North America, skip to section 3.2, “Configure
the Survey Receiver”; if you are using the device in Australia or New
Zealand, you will need to configure the survey transmitters.
Select EN1223SK Survey Transmitter Frequency Band
1.
Use the small Phillips head screwdriver to remove the three housing
screws on the back of the unit.
2.
Remove the front of the housing.
3.
Place a selection jumper on the appropriate frequency band selection
pins (figure 5).
• 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.

6.
Use your thumb to press the housing release tab on bottom of the
transmitter; separate the housing.
7.
Place a selection jumper on the appropriate frequency band selection
pins (figure 6).
• Place the jumper on the left two pins, marked AUS, 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.
