*In loaded operation, the voltage of battery is reduced, and LED changes correspondingly; the
higher load power is, the more obviously LED changes.
* In loaded operation, in case that the indicator light “Power” (displaying output power) flickers
continuously and the buzzing occurs for over 5s, then the equipment is locked automatically, which
indicates that the existing electric quantity of battery cannot afford the load, so please reuse if after
charging.
Status LED Lamp Alarm
During charging the flash, the instantaneous power may be increased by more than 3 times, e.g. for
100WS flash, its transient current may be equal to that of a 300W lamp. Therefore, when using
certain flashes, the indicator light “Power” may flicker with short buzzing, which is normal as the
instantaneous power of the flash has exceeded 750W.
If the indicator light “Power” (displaying output power) flickers continuously, occurring buzzing for
over 5s, the equipment will be locked automatically.
After locking the equipment automatically, you only need to turn off the mains switch, and then turn it
on to reuse.

2.2 Mode Switch
LP750X Inverter is equipped with two operating modes including “Normal” (normal mode) and
“Flash” (flash mode). Users can choose one of the working modes according to the loaded
machine. The “Flash”(flash mode) is specially designed pursuant to the performance
characteristics of flashes, also supporting the use of electrical appliances with rated power;
however, no power-down mode is provided and the standard battery can stand by for 13 hours
continuously in this mode.To the electronic products that continuously output rated power, , it is
recommended “Normal” (normal mode) should be used, because it can save electricity; in this
case, the standard battery can stand by for 48 hours continuously; in the mode, flashes cannot be
used. As for detailed data, see the following “Introduction to Function Mode”.
2.3 Main Switch
“OFF” refers to power off;
“ON” refers to power on; at the moment, the equipment can be used;
“USB” refers to USB charging starts, at the moment, the USB indicator is lit on and portable
products can be charged e.g. iPhone, iPad, etc. There is no AC power output in USB mode.
USB 1/USB 2: output 5V/2A x 2.
2.4 AC Output Socket
* Two AC output sockets are parallel, and each of them can output the maximum power.
* AC output standard voltage is 230V/50Hz. If additional requirements are from some special
voltage, please consult our relevant personnel prior to purchase.
Note: when turning the Flash (flash mode) mode to standby mode, you need to turn off the power
inverter at first. Then, turning it on to finish setting.
