After recording, it will turn back on automatically. Cinema mode is bound to metadata support.switches the fans on permanently. X switches the fans off.

CAUTION!
For a long product life, we highly recommend NOT to operate your DC-LINK with permanently switched-off fans. Whenever you are operating your devices without cooling, monitor the temperature and make cooling breaks when the indicator on your display is flashing(60°C/140°F). THE DEVICES DO NOT HAVE AN EMERGENCY OUT! If you allow your devices to get too hot, you might cause serious damage of your equipment.

Encryption

In encryption mode, the transmitter sends an encoded signal that only linked receivers can read, making it easy to protect confidential content that is not meant for everyone’s eyes.

To activate encryption mode, press the MENU button until ENC is flashing. Use + or – to check either ✓ENC or XENC and confirm with MENU.
To link your devices, set your transmitter and all the receivers to the same channel, then activate encryption on your transmitter.
All receivers will follow into encryption mode automatically. Settings remain active after turning your devices off. This means that ENC can be prepared prior to shooting and will stay active unless you turn it off.

A linked receiver does not HAVE to stay linked. To take a receiver out of the encrypted system, simply turn off ENC.
Then you can easily access another (unen-crypted) transmitter’s images by choosing the referring channel within seconds. To link back to the previous (encrypted) transmitter, turn ENC on again.

IMPORTANT:
Switching back and forth between two encrypted systems is not possible. You cannot slip into an encrypted wireless system, if your receiver was not initi-ally linked to the transmitter. If you want to add a new receiver to an encrypted system, you need to link the whole system again.
