Q:  Why is the battery meter higher when I restart than when I shut off the transmitter?

A: Line 6 2.4G wireless transmitters have a circuit that measures the actual real-time voltage of the installed batteries and transmits that data to the battery meters in the receivers.  The battery meters are very accurate when they have been running continuously since new batteries were installed in the transmitter and the transmitter power has not been cycled on and off.  However due to the chemical nature of Alkaline batteries, when they have been shut off, the voltage begins to “rebound “ and the voltage actually increases compared to its value at shutoff.  Unfortunately it does not last long and it reverts to true self over twenty minutes or so. For this reason when you first turn on a Transmitter that has been run but allowed to rest the meter will give a high reading that quickly falls over the first few minutes and continues to fall quickly for the first few minutes.  This is normal behavior for Alkaline batteries.

Q:  Why does my wi-fi slow down when I get my transmitter near my computer?

A: Because wi-fi and Line 6 2.4G wireless products share the same bandwidth some users may experience a slowing down of their wi-fi capabilities when using microphone or instrument transmitters near computers.  This is an example of a near/far interference problem and it is heightened because consumer grade wi-fi  has very low power.  If your Line 6 transmitter gets within 6 feet of your laptop you may witness this situation especially if your wi-fi access point is some distance away.  Typically simply moving your Line 6 transmitter farther away from your computer will remedy the situation.  Users of Line 6 twelve channel systems should switch their transmitters to the “low power” setting as this will mitigate the problem as well.

Q:  What does the Near/Far spec mean to me?

A: The Near/Far interference problem is common to most radio systems and happens when a strong signal captures a receiver making it difficult or impossible for the receiver to decode the weaker signal.

Imagine having a conversation in a quiet room with a person 20 feet away from you.  It is likely that you can carry on a conversation with normal voice levels.  Now if you move to a noisy environment, with lots of other voices right around your ears it may be very difficult for the conversation to continue with your long distance friend without the both of you shouting.

A similar circumstance occurs with radios and since the long distance transmitter is incapable of increasing its power output it is very likely a very near transmitter may interrupt it.

In the real world this is rarely an unmanageable problem.  You should avoid being closer than 3 feet to a receiver that is not on your channel if the intended transmitter is more than 50 feet from this receiver.  If this is a regular requirement you will need to remote your antennas (G50, G90 XD-V70).
