Changing Settings (FN and SN)

The IMB5 can be adjusted to specific requirements by changing System settings. This is done by entering the function number (FN) and then the setting number (SN).

Step 1: Entering Function Number (FN)

Option 1 and Option 2 for FN entering

Preparation:

1. Switch ID card to passive (orange) mode.
2. Enter the PIN code (see Entering Service Mode).
3. Wait 3 seconds with ignition OFF until the LED starts blinking in frequent flashes. You now have 80 seconds to start.

Step 2: Changing Setting Number (SN)

Changing SN and saving settings - Part 1

Changing SN and saving settings - Part 2

How to change settings:

• Option 1 (Ignition Key): Use the ignition ON/OFF to enter digits. For example, to enter FN21: 2 turns (wait for double flash), then 1 turn.
• Option 2 (Authorization Button): Press the button according to the digits (e.g., 2 presses, 1 second pause, 1 press).
• Confirmation: A short buzzer sound confirms the FN is entered. A long buzzer sound (2-3 seconds) shows that valid SN is entered successfully.

Exit: Enter FN11 to leave the service mode.
