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.

● 本品不是玩具，14岁以下儿童使用需要有成人监护；
● 请勿在高温、潮湿的环境下使用；
● 在强烈振动环境使用本产品时，应做好缓振措施；
● 请勿将VR Pro整个包裹后使用；
● 由于输出电流较大，请采用2根输出线连接至接收机；
● 本产品支持电压切换，使用此电压时，请确认你的接收
机、舵机或其他设备支持该电压；
● 不要在稳压器工作时切换输出电压；
● 输出端绝不可以短路；
● 为确保VR Pro正常工作，请遵守下面的公式，将发热功
率限制在安全范围内：
（1）(输入电压 - 输出电压) x 输出电流 <= 10W；
（2）如果长时间大于10W，温度会快速上升，可能会损坏
稳压器，请特别注意；
（3）安装冷却风扇（#46816，选配件），热功率可以提
升至15W；
（4）VR Pro不会因为输入电流过大而停止工作，但内部
极限工作温度为120度，超过控制IC将损坏。
● 该产品电压指示和报警按照锂聚合物电池预设；
● 如果你长时间（24小时内）不使用VR Pro，请断开和电
池的连接，因为待机状态下也会有2mA耗电。
注意事项：
电源效应：%0.3
电压效应：%0.3
输出纹波：≤2mV
外形尺寸：53mm X 32mm X 18mm
主机重量：30g（不含配件）
使用说明：
VR Pro采用水平排针作为
输入输出，如右图。按稳压器
标签指示，左边两路排针为电
池输入插口，电池通过输入转
接线（Input adapter）接入
VR Pro。中间两路为稳压输出
插口，VR Pro 通过输出线
（#46815）与接收机相连。右边
分别为风扇和控制开关插口，
只要对应连接即可。通过另一侧的3档开关可以选择输出电
压，分别是5V/6V/7.4V。我们建议采用双天20C系列2S锂
聚合物电池为VR Pro供电。上述连接确认无误后，将
FSS-4拨动到“ON” 即可工作。
工作中，内置3色监视器显示电池电压：7.4V以上，绿
灯亮，7.4V-7V，黄灯亮，如果电压低于7V，红灯亮，此时
应尽快停止使用。红灯警告有记忆功能，表示电池曾经故
障（电量低、接触不良或系统过载），关闭开关后重开可
以消除记忆。
FSS-4电源开关、电压显示电路和输出电压选择开关均
采用Fail safe“失效安全”设计。任何故障不会主动关断
VR Pro的电力输出。当电压选择开关失效后，输出电压被设
定在5V。
