Spektrum SPMAR6255 - Manual (Page 8)

Note: The latest generations of Nickel-Metal Hydride batteries incorporate a new
chemistry mandated to be more environmentally friendly. These batteries,
when charged with peak detection fast chargers, have tendencies to
false peak (not fully charge) repeatedly. These include all brands of NiMH
batteries. If using NiMH packs, be especially cautious when charging,
making absolutely sure that the battery is fully charged. It is recommended
to use a charger that can display total charge capacity. Note the number
of mAh put into a discharged pack to verify it has been charged to full
capacity.
QuickConnect ™ With Brownout Detection
Your AR6255 features QuickConnect with Brownout Detection.
• Should an interruption of power occur (brownout), the system will reconnect
immediately when power is restored (QuickConnect).
• The orange LED on the receiver will flash slowly indicating a power interruption
(brownout) has occurred.
• Brownouts can be caused by an inadequate power supply (weak battery or
regulator), a loose connector, a bad switch, an inadequate BEC when using an
electronic speed controller, etc.
• Brownouts occur when the receiver voltage drops below 3.5 volts thus
interrupting control as the servos and receiver require a minimum of 3.5 volts
to operate.
How QuickConnect With Brownout Detection Works
• When the receiver voltage drops below 3.5 volts the system drops out (ceases
to operate).
• When power is restored the receiver immediately attempts to reconnect to the
last two frequencies that it was connected to.
• If the two frequencies are present (the transmitter was left on) the system
reconnects typically in about a fraction of a second.
QuickConnect with Brownout Detection is designed to allow you to fly safely
through most short-duration power interruptions; however, the root cause of these
interruptions must be corrected before the next flight to prevent catastrophic safety
issues.
Note: If a brownout occurs in flight, it is vital that the cause of the brownout be
determined and corrected.
Flight Log (SPM9540 Optional)
The Flight Log is compatible with the AR6255. The Flight Log displays overall RF
link performance as well as the individual internal and external receiver link data.
Additionally it displays receiver voltage.
Using the Flight Log
After a flight and before turning off the receiver or transmitter, plug the Flight Log into
the Data port on the AR6255. The screen will automatically display voltage e.g. 6v2=
6.2 volts.
Note: When the voltage reaches 4.8 volts or less, the screen will flash indicating
low voltage.
