1. If you plan to install several lamp units and synchronise them with each other, make sure that only one of them is connected as "MASTER''. NOTE Only lamps of the same type and with the same number of programmes can be synchronised.
2. The Master, Slave function of the lamp is selected by connecting the white wire for the MASTER lamp or the yellow wire for the SLAVE lamp respectively to the (-) power supply of the vehicle.
3. Changing the synchronisation method to counter-phase flashing is only possible to set in the SLAVE lamp unit, but without connection to the MASTER circuit. During operation of the SLAVE lamp(s), the white colour lead should be shorted to (-) of the power supply for about 5 seconds. The change will be confirmed by skipping one series of flashes. Shorting the white lead to (-) of the power supply again in SLAVE mode will set the lamp to synchronise in phase. All SLAVE lamps for which the phase of operation is to be changed can be switched together.
4. To change the pattern, short-circuit the synchronisation line for approximately 1 second to the (-) of the power supply. The MASTER lamp enforces the pattern number on the SLAVE lamps.
