Releasing channels that are used or subject to interference

After the scan, the channels that are occupied or subject to interference are marked with a warning triangle and the text “Freq. occupied” in the “Tune” menu. Via the “Scan reset” menu, you can unmark these channels. The last scan result is deleted.

￿Turn the jog dial 7 until the arrow points to “Scan reset”.

￿Press the jog dial 7.

The number of free channels is reset to the maximum for all frequency banks.

￿Turn the jog dial 7 to select a frequency bank.

￿Press the save button 8.

The selected frequency bank is automatically called up in the “B.Ch” menu.

Multi-channel operation

Combined with Sennheiser 3000 and 5000 series transmitters, the receivers can form transmission links that are suitable for multi-channel operation.

CAUTION! Risk of reception interference!

If – within the receiver’s frequency range – transmitters transmit on channels from different frequency banks, reception can be subject to interference and inter-modulation. Only the factory-preset frequencies within the frequency banks “1” to “6” are interference and inter-modulation free.

￿Set all transmitters of a multi-channel system to different channels within the same frequency bank.

Before putting the transmission links into operation, we recommend that you perform a scan in order to find a frequency bank with a sufficient number of free channels:

￿Switch all transmitters off.

￿Use a receiver to scan all frequency banks for free channels (see “Scanning the frequency banks for interference-free channels” on page 33).

￿Select a frequency bank with a sufficient number of free channels (see “Selecting a frequency bank and a channel” on page 28).

￿Set each transmitter/receiver pair in your multi-channel system to a different free channel within this frequency bank.
