Manipulation with the programmed device

After selection of desired device for your work, you can insert into the open ZIF socket (the

lever is up) and close socket (the lever is down). The correct orientation of the programmed

device in ZIF socket is shown on the picture near ZIF socket on the programmer's cover. The

programmed device is necessary to insert into the socket also to remove from the socket

when LED BUSY light off.

Warning: 844USB programmer hasn’t protection devices, which protect the content of

programmed device against critical situations, for example power failures and PC failure

(interrupted cable...). Moreover, a device is usually destroyed in the programming mode due

to forced interruption of the control program run (Reset or switching the computer off) due to

removing the connecting cable, or unplugging the programmed device from the ZIF socket.

Incorrectly placed device in the ZIF socket can cause its damage or destruction.
