1.2 Memory Chip Installation

The access controller is shipped with two memory chips packaged in a separate box inside the

shipping container. The memory chips must be installed for the system to operate.

CAUTION!! Do not install the memory chips with power to the system turned on. Attempting

to install the memory chips with power on will irrevocably damage the chips. Memory chips

are a static sensitive component. Discharge any static electricity from your hands by

touching a proper ground device before removing the control board. Handle the memory

chips with care.

1. The large memory chip socket is colored black and is located in the center of the circuit

board. Be sure that the handle is in the un-locked position (pointing up). Be sure that

power to the telephone entry system is off.

2. Carefully insert the memory chip into the socket. The small half circular indentation on

the chip must be to the right. CAUTION: Installing the memory chip backwards will

cause permanent damage to the chip. Be sure that the memory chip is seated correctly

in the socket, then move the lever to the locked position.

3. Install the small memory chip in the socket located at the bottom of the circuit board. The

small circular indentation on the chip must be to the right. CAUTION: Installing the

memory chip backwards will cause permanent damage to the chip. Be sure that the

memory chip is seated correctly in the socket.
