General Information
The following section is provided to help you with questions about your Commander Echo Wireless Functional
Testing System.
What happens if I take the instrument out of range during a test?
If the instrument is transmitting to the receiver when it moves out of range (beyond 3 meters),
communications for all active instruments can be lost and the data cannot be retrieved. To re-establish
communications, move the instrument back within the transmission range and restart the test.
Can my Commander Echo receiver pick up signals from other devices like wireless phones or wireless
networks?
Wireless networks, cordless phones or other devices can potentially cause interference with your Commander
Echo System. As a precaution, we recommend that you minimize their usage within the transmission range
of your Commander Echo System. We have taken every precaution and tested to the highest standards to
ensure accurate data transmission with your System. The main reason for linking your Commander Echo
instruments with your Console is to reduce the potential for unintentional data transfer from other devices,
including other Commander Echo systems operating in the area. We have also incorporated state-of-the-art
methods, such as direct sequence spread spectrum, modulation, and unique device identification to reduce
the possibility of miscommunication.
Is there any other type of interference I need to worry about?
As with any radio transmission, high-powered electromagnetic devices should be avoided. For example, you
should not operate your system near microwave ovens or X-ray machines.
Can I block the signal during testing?
Unlike infrared systems, Commander Echo is not based on line of sight, so standing between the instrument
and the receiver should not interfere with the signal, provided you are within the operational distance.
How do I know when the instrument’s battery is low?
The LED on the instrument will begin rapidly blinking Red instead of Blue when connected (see the
instrument LED codes on page 5). Additionally, there is a “low battery” indicator on the Console’s LCD
screen. If the LED is Rapidly blinking Red, this indicates that less than 20 minutes of battery power remains.
How long do instruments continue to operate after the low power signal?
The amount of operational time for each instrument varies, but approximately 20 minutes. Like a cell phone,
the instrument uses more power when active and sending data than when in the off power state. Our
recommendation is to place the instrument on the charger as quickly as possible after the low power signal
comes on.
