Alpha 4000 is an advanced industrial remote control. It can be widely applied to the industrial purposes, such as: various cranes, tower cranes, production machinery. auto-machinery, auto control machinery ... etc.

Professional and wise design
Visualized Software
It allows you to set every function of your remote control via software. Base on the system type selected, you may create all kinds of combination with the software to fit different working environments.
The 5 LEDs show the status Transmitter is designed with
The LED on the middle top Shock absorbing
of the transmitter shows the The shock absorbing rubbers
current status of the radio on the four corners of
remote control whereas the transmitter strengthen the
rest of the 4 LEDs show the shock absorbing ability current status of the
pushbutton setting.

Alternative in Startup
The transmitter is equipped with either On/Off key switch or infrared startup.
Electromagnetic induction charge .
Undisclosed metal and open typr of battery charger provides immediately
charging simply by placing the transmitter on the charging holes

Chip Card - function set via chip card
Breakdown update
if any remote control is out of order, you simply need to take out the chip card from chip card holder and insert it into the chip card slot of the same system
type to proceed with the operation,  

Same system type copy
Chip card data backup can be done by file saving / reading via chip card programmer. If same function and setting are needed in the future, you only need tore-call the original file and correct/save data in the chip card.

Setting/Modification for any function
Remove chip card and modify the desired function via software.

Changeable PCB
The Alpha 4000 receiver is designed with changeable PCB.
It allows the expansion or modification of function settings simply by changing relay cards

Frequency adjustment and drift correction on PILL RF module
PLL ( Phase Lock Loop ) synthesized RF module with user-selectable RF Channels ( narrow band FM ) for the transmitter code transmission.
transmitter and receiver channels are changeable. frequency is also adjustable and can be corrected for any frequency drift automatically and manually.
