3. Q: I’ve heard that the DSM system is less tolerant of low

voltage. Is this correct?

A: All DSM receivers have an operational voltage range of 3.5 to 9

volts. With most systems this is not a problem as in fact most

servos cease to operate at around 3.8 volts. When using multiple

high-current draw servos with a single or inadequate battery/

power source, heavy momentary loads can cause the voltage to

dip below this 3.5-volt threshold thus causing the entire system

(servos and receiver) to brown out. When the voltage drops below

the low voltage threshold (3.5 volts), the DSM receiver must

reboot (go through the startup process of scanning the band and

finding the transmitter) and this can take several seconds. Please

read the receiver power requirement section as this explains how

to test for and prevent this occurrence.

4. Q: Sometimes my receiver loses its bind and won’t

connect requiring rebinding. What happens if the bind

is lost in flight?

A: The receiver will never lose its bind unless it’s instructed to. It’s

important to understand that during the binding process the

receiver not only learns the GUID (code) of the transmitter but the

transmitter learns and stores the type of receiver that it’s bound

to. If the transmitter is placed into bind mode, the transmitter

looks for the binding protocol signal from a receiver. If no signal

is present, the transmitter no longer has the correct information

to connect to a specific receiver and in essence the transmitter

has been “unbound” from the receiver. We’ve had several DX7

customers that use transmitter stands or trays that unknowingly

depress the bind button and the system is then turned on losing

the necessary information to allow the connection to take place.

We’ve also had DX7 customers that didn’t fully understand the

range test process and pushed the bind button before turning on

the transmitter also causing the system to “lose its bind.”

If the system fails to connect, one of the following has occurred:

• The transmitter is near conductive material (transmitter case,

truck bed, etc.) and the reflected 2.4GHz energy is preventing the

system from connecting. (See #2 above)

• The transmitter was put into bind mode knowingly (or

unknowingly), causing the transmitter to no longer recognize

the receiver.
