TUNE Locking channels for the user

Via the “TUNE“ menu you can lock certain channels so that the user

cannot select them. This makes sense when several guided tours take

place at the same time and several transmission links are operated

simultaneously. As only the selectable channels are displayed, the

user can quickly switch to the channel stated by the guide.

Select the channel you like to lock as described within the chapter

“Changing the receiving frequencies of the channels” on page 18 and

confirm your selection by pressing the SET button.

The current receiving frequency of the selected channel flashes on

the display.

 Use the / rocker button (UP/DOWN) to select the character

string “---.---“. This string follows the frequency 866.000 MHz and

precedes 830.000 MHz.

 Press the SET button to store your setting.

This channel is now locked is no longer displayed for the user.

Releasing locked channels

Via the “TUNE“ menu you can release locked channels.

 Select the channel that you would like to release.

 Use the / rocker button (UP/DOWN) to select the frequency

that you would assign to the channel.

 Press the SET button to store the setting.

 The user can now select the channel again.

SQELCH Adjusting the squelch threshold

The receiver is equipped with a squelch that can be adjusted via the

“SQELCH” menu. The squelch eliminates annoying noise when the

transmitter is switched off. It also suppresses sudden noise when

there is no longer sufficient transmitter power received by the

receiver.

Note:

Before adjusting the squelch threshold to a different setting, use

the volume control  to set the volume for the connected

headphones to the minimum.

There are three possible squelch settings:

y SQ LO = low

y SQ MID = middle

y SQ HI = high

1 2 ... 14 15 16 17 18 19 20 21 22 23 24 ... 61 62
