Introduction to Programming
Before You Start Programming
Concept of 308M (Main Unit)
The 308M(Main Unit) has Flash Memories and RAM. The System Software (Program) will be stored the
Flash Memory area, and the customer data will be stored to the RAM.
1. Flash Memory
For the initial installation, the System will start up from Flash Memory. The data in the Flash Memory is
put by the Factory. In case of the Software Up grading, the new System Software (Program) is loaded
from a Compact Flash Card to Flash Memory.
2. RAM
After starting up the system and completing the programming, all customer data will be stored to the
RAM. It will be saved by Lithium Battery even if the power is going to be failed. For your safe, the
customer data can be stored to Compact Flash Card or your Hard disk of Personal Computer.
System Start-Up
There are 4 types of Start-up Operation made as below.
1. Initial Installation(COLD Start)
This mode may be selected in case of first installation. The System Software(Program) will be loaded
from Flash Memory to the RAM.
• When entering Programming Mode at first time, the operation is as follows;
1) The SW1 on the 308M unit will be set at the left side to "C" and turn System Power Switch to ON.
2) Wait until 1-2 minutes, LED2(RUN) is going to be lit and the Key Telephone's display shows Time
& Date with Extension number.
After you change System Data, you must set the SW1 knob to right side to "H" to protect your System
Data. This switch must always remain in the "H" position for normal operation.
2. Software Upgrading
This mode may be selected in case the existing system is upgraded. The existing System Software
(stored to the Flash Memory) will be cleared, then the new System Software will be loaded from new
Compact Flash Card. The existing Customer Data (stored to the RAM) will be cleared.
• When the existing system is going to be upgraded, the new software will be loaded from Compact Flash
Card. And EXIFU-A1 unit is required. The operation is as follows;
1) Make sure the Back-up Battery (Lithium Battery) has been installed completely and the SW1 on the
308M unit must be set "H" position to protect the customer data.
2) If previously powered up, the system must be turned off for upgrading software.
3) Once the system has completed its power down cycle (LED is off), insert the Compact Flash Card
containing the software upgrade into the Compact Flash Card Slot(CN4) on the EXIFU-A1 unit.
4) SW1 is set to "C" side. Turn the system power switch to On.(LED status are as followings.)
5) Wait until 1-2 minutes, when the loading is completed, the fast blinking of LED4 will stop.
6) SW1 is set to "H" side and Power Off the system.
7) Remove the Compact Flash card from the Compact Flash card slot.
8) Power On the system. Wait until 1-2 minutes, LED2(RUN) is going to be lit.
9) Confirm the Main Software Version Number by "OPAC" and "Dial 3".
