Frequently Asked Questions On Spektrum 2.4GHz
1. Q: After I've bound the receiver to my transmitter, which do I turn on first,
the transmitter or the receiver?
A: Every Spektrum transmitter has a GUID (Globally Unique Identifier) code
imbedded in its signal. When you bind a Spektrum receiver to your transmitter,
this GUID code is stored in the receiver. If you turn the receiver on before the
transmitter, you don't have to worry about it responding to another transmitter.
The receiver will wait for a signal from the transmitter with the same GUID
code it has stored.
If the transmitter is turned on first you can expect it to connect within 15
seconds of powering on the receiver.
2. Q: Sometimes the system takes longer to connect and sometimes it doesn't
connect at all. Why?
A: In order for the system to connect, the receiver must receive a large number
of uninterrupted signal packets from the transmitter. This process takes just
a few seconds, but if the transmitter is too close to the receiver (within 4 feet)
or near metal objects (such as a metal transmitter case, metal truck bed, or
metal work bench) it may detect its own reflected 2.4GHz energy as "noise".
This can delay or prevent connection.
If this happens make sure you are a sufficient distance from metal objects
and the receiver itself before you power up and try again.
3. Q: Is it true that Spektrum systems are less tolerant of low voltage?
A: All Spektrum receivers require at least 3.5V to operate normally. Most servos
cease to operate below 3.8V. Using multiple high-voltage servos, however,
with an inadequate power supply can allow voltage to momentarily drop below
3.5V. This will cause the receiver to "brown out" and reconnect.
All recently manufactured JR and Spektrum 2.4GHz receivers feature
QuickConnect technology that will reconnect the system within a quarter of a
second should a brown out occur.
4. Q: Sometimes when I power on my Spektrum system I notice the receiver
won't connect and it needs to be rebound to the transmitter. Can this
happen in use?
A: No. The receiver cannot be unbound from its transmitter without specific
action by the user. You can accidentally unbind a receiver by inadvertently
putting your transmitter into bind mode. If this happens and the transmitter
doesn't detect a binding signal from the receiver it can cause the receiver to
be unbound.
If your system fails to connect, chances are much greater that it's the result of
one of the following conditions and not because the receiver is unbound.
1. You've selected the wrong model memory.
2. The transmitter is too close to conductive material to connect
(see FAQ 2).
