After selection of desired device for your work, you can insert

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: 849 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
