Locking Settings

Press ON/OFF and SELECT simultaneously to lock or unlock transmitter settings. When locked, the current settings cannot be

manually changed.

Note: Locking the transmitter settings does not disable IR frequency synchronization or the High Pass/Low Cut filter.

Logic Mode

To use with a logic enabled receiver, you must perform an automatic sync. The LCD flashes "log" during sync. Once in logic

mode, the LCD flashes "log" when powered up.

Automatic Frequency Synchronization

Power off all transmitters.

Begin with the first transmitter. Open the battery cover and power it on.

Aim the IR sensor at the first receiver IR port. The transmitter should be no more than 15 cm (6 in.) from the receiver.

Press and hold the receiver SYNC

button to send group and channel data to the transmitter. The red LED on the trans-

mitter will stop flashing when programming is complete.

Power off the first transmitter and repeat the synchronization with each additional transmitter and receiver pair.
