			# If the FN code is not entered due to an error, wait for frequent flashes of the System LED and try again.
			# If the FN code is not entered because the 8-minute Control time has elapsed, enter the Setup Mode again.
			# The SN indication can be cancelled by a short press of the Secret Button or by turning ON the ignition for a short time (if the FN code was entered by the ignition key).
			# '''FN31, FN32, and FN34 – Sensitivity Adjustment/Testing:'''
			#* When one of these codes is entered, the System indicates the current SN value by flashing the System LED once.
			#* You can now test the sensor sensitivity; a trigger will be indicated by a short siren signal.
			#* The sensitivity (SN value) can be adjusted at any time while the test mode is active. After changing the SN value, the new value will be displayed once more, allowing for further testing.
			#* To exit this mode, briefly press the Secret Button or turn the ignition ON (if the FN code was entered by the ignition key).

			=== 9.3. SERVICE MODE AND SETUP MODE ===

			* '''Setup Mode''' is activated for 8 minutes after the PIN code is entered. This mode is dedicated to the manual change of the System settings using FN and SN codes. Note that each entry of an FN or SN code extends the control time for another 8 minutes.
			* '''Service Mode''' is dedicated to the emergency shutdown of the Alarm system. The system automatically enters Service Mode after the 8-minute control time has elapsed, provided no FN or SN codes were entered.

			== 9. MANUAL CHANGE OF THE ALARM SYSTEM SETTINGS ==

			=== 9.1. PIN, FN AND SN CODES ===
			To configure the system, you will need to use the following codes:

			* '''PIN''' – A 4-digit code required to activate the Setup Mode and the Service Mode.
			Note: The factory PIN code is printed on the Alarm System label. It is strongly recommended to change the factory PIN code after the system installation.
			* '''FN''' – Function Number – A 2-digit code used to select the specific function that needs to be changed.
			* '''SN''' – Setting Number – A 1-digit or 2-digit code used to select the desired setting value for the chosen function.

			== 8. AUTOMATIC VEHICLE DETECTION ==

			=== 8.1. CAR DETECTION PROCEDURE ===
			If the car was not selected manually from the list (by PC using installed GN7C Loader software, see 6), when the System is powered up, the car detection procedure is automatically activated – the System LED blinks quadruple flashes. In order for the Alarm System to identify the car in which it is installed, it is necessary to fulfill the following:

			<center>
			[[File:GN7C_Car_Detection_1.png\|600px\|thumb\|none\|Pic. 6. Automatic car detection steps.]]
			</center>

			If the car detection procedure failed (there was no long flash of the System LED confirming the successful learning of the System), however the System detected the ignition ON and the System LED blinks double flashes, proceed as follows:

			<center>
			[[File:GN7C_Car_Detection_2.png\|600px\|thumb\|none\|Pic. 7. Troubleshooting steps for failed car detection.]]
			</center>

			'''NOTES. If the Alarm System learning (automatic vehicle detection) failed:'''
			* Repeat the procedure of automatic vehicle detection from the beginning, only this time, first turn ON the ignition and turn ON the power of the Alarm System with the ignition ON.
			* Check if the CAN bus and ground wires are well connected, and whether the System is connected to the correct CAN bus.
			* Update the Alarm System firmware and repeat the Alarm System learning procedure.

			=== 8.2. OTHER VEHICLE DETECTION ===
			If the Alarm System was used in one car and later installed in another car, it is necessary to re-execute the vehicle detection procedure or select the car manually (using a computer with the installed software GN7C Loader). To start the automatic car detection procedure, follow these steps:
			# '''a)''' Enter PIN code (see 9.2).
			# '''b)''' Within 8 minutes after entering the PIN code enter the code 59 (Fn59).

			=== 8.3. IMPORTANT TO KNOW ===
			* Vehicle detection procedure can be cancelled by Service Button press. The System terminates the detection procedure and remains in Setup Mode.
			* After a successful car detection procedure the System automatically goes into Normal Mode and you can start using the System immediately.

	# '''Optional Controls:''' If additional equipment is installed (e.g., additional engine immobilization circuits, engine preheating modules), connect them using the ''Optional control No.1'' and ''Optional control No.2'' outputs. The purpose of these outputs can be configured via settings for FN51 and FN52.		# '''Optional Controls:''' If additional equipment is installed (e.g., additional engine immobilization circuits, engine preheating modules), connect them using the ''Optional control No.1'' and ''Optional control No.2'' outputs. The purpose of these outputs can be configured via settings for FN51 and FN52.
			== 7. THE SYSTEM TRIGGER DATA ==

			The Alarm System saves information about the last triggers and can indicate the trigger reasons in two ways:

			* '''a)''' Disarm the System, close the doors, and turn ON the ignition. The System will indicate the reason for the last trigger via direction indicator flashes (and siren signals, depending on settings).
			* '''b)''' Enter FN71, FN72, or FN73. The System will indicate the reason for one of the last 3 triggers via direction indicator flashes (and siren).

			=== Trigger Identification Table ===
			The following table defines the reason for the trigger based on the number of flashes/signals:

			{\| class="wikitable" style="width: 100%; text-align: center;"
			\|- style="background-color: #f2f2f2;"
