System Software Installation Overview

1. 1. Remove C.U. lid.
   2. Check the system software version. If it is NOT a CGMT version,(label says CGMT Vx.x) remove it and replace with (GGMT V2.0) system software eprom. (Fig.4) (For further eprom replacement instructions see Procedure1 below.)

Procedure 1. EPROM REPLACEMENT

Remove cover, from central unit.

1. 1. Refer to the drawing below for correct eprom locations. (Fig.4a)
   2. Remove the old system eprom, from the main board. Be careful to pull the eprom out
      without bending the legs.
      NOTE: Ensure the notch is in the correct direction. Notch on eprom must match the notch on the socket and markings on the board.
   3. Place new eprom in the correct eprom socket as shown. Carefully align the new eprom legs with the socket and push the eprom into place. Be careful not to bend any of the legs.

Fig.4a

Procedure 2. Strain Relief Installation

1. 1. Remove existing cable, ferrite filter and strain relief from central unit. (Fig. 5)
