How to use
VR Pro adopts a horizontal row
as input and output port, (see the
right picture). According to the label
instructions, two sockets on the left
are for battery input. The battery can
be connected to VR Pro by the input
adaptor. The middle two sockets are
for stabilizing output. VR Pro is
connected to the receiver by the output
wire (#46815). Two sockets on the right side are respectively for fan
and control switch. There is a three gear switch on the opposite side,
which can select the output voltage from 5V / 6V / 7.4V. (We suggest to
use Dualsky 20C series 2S li-po battery for VR Pro) When these wires
are correctly connected, please put FSS-4 to the" ON" position to work.
During working, the built-in tri-color monitor displays battery
voltage: over 7.4V with green light, 7.4V to 7V with yellow light, lower
than 7V with the red light. When the red light on, the user should stop
using as soon as possible. The red light warning has memory function,
it indicates that the battery has fault (low voltage, poor contact or
system overload). Close the switch and re-open it can reset the
memory.
FSS-4 switch, the voltage display circuit and the output voltage
select switch are all using the "fail safe" design. Any fault will not take
the initiative to turnoff VR Pro power output. When the voltage select
switch fails, the output voltage will be set to 5V.

Safety attentions (Failure to follow these instructions can be
damage your product, and cause serious bodily injury or death.)
● Not suitable for children under 14 years old without adult guidance;
● Do not use it in the high temperature or humid environment;
● When using this product in strong vibration environment, vibration
mitigation measures should be used;
● Do not cover VR Pro in use;
● Since the output current is large, please use 2 output wires to
connect the receiver;
● This product supports switching voltage. Please select the voltage
according to the supply voltage of your receiver, servo or other
equipments;
● Do not change the output voltage while VR Pro is working;
● Output port short circuit will damage VR Pro;
● In order to ensure the VR Pro working properly, please obey the
following formula to limit the thermal power in a safe range:
(1) (input voltage - output voltage) x output current < = 10W;
(2) Please pay special attention to that, if the VR Pro current
is over 10W for a long time, the temperature will rise quickly,
it will damage the regulator;
(3) When the cooling fan is mounted (#46816, optional), the
thermal power can be increased to15W;
(4) VR Pro will not stop working when the input current is too
large. But the internal limit working temperature is 120
degrees. When the temperature is more than this limit, it will
damage the control IC.
● The voltage indication and alarm is preset according to the lithium
polymer battery.
● Notes: If you don't use the regulator in 24 hours, you'd better
disconnect it from the battery because it remains a 2mA quiescent
current.
