When the key switch is set to "ON" and 
programming is performed normally, the led 
switches on as shown in the figure.

 

WITH MASTER KEY

 

After the confirmation flash when switching to 
"ON", a number of flashes are emitted, equal 
to the number of keys used for programming.

 

WITH SERVICE KEYS

 

PGO BR-500 ENGINE

If the vehicle is not used, the deterrent lightstops automatically after 48 hours to prevent discharging the battery. A 
new48-h cycle starts by switching from "OFF" to "ON" and"OFF" again.

 

 

 
 

Switching from "ON" to "OFF" with 
programmed system causes the intermittent 
switching on of the led, with an anti-theft 
effect.

 

This occurs with any key used for 
programming.

 

The information will be as follows:

 

- Blank controller OFF

 

- Start-up disabled OFF

 

- Number of keys 2*

 

*The number denotes how many keys have been usedfor programming, master key included.
