Information on How to Use This Manual
This operator manual and the operating manual TVS-D 660 should be used side by side, as the information in both manuals is interdependent.
NOTE: All necessary settings for the specific transmitter position have
already been entered in the factory. There is no need for any re-adjustment!

HOME Menu
The sub-menus are all accessible via keys. In the HOME MENU the following parameters are permanently displayed:
Parameter Remark
L, R, M, A*, B* Indication of the operation mode toggels
between L (local) , R (remote), M (monitoring), A* (active devices) and B* (backup devices).
ERROR/ WARNING/ INFO Indication of present errors / warnings/
additional information
* only in a spare sytem
Three operation modes are available to meet different user requirements:
In the LOCAL operation mode remote control is completeley disabled (no remote control
- signalling depends on the local setting).
In the REMOTE operation mode (so in A and B ) local indication, but no local control is possible.
In the MONITORING mode local control is possible only after entering the password (local password-protected mode).
Use the remote switch on the front-panel to switch between local and remote operation mode.
Move the cursor to SIGNALING IF LOCAL to switch the remote signalling for local operations on or off.
NOTE: Only visible if the remote interface is selected in the installation
menu
Change to the ACCESS submenu in the MISCELLANEOUS menu to activate/deactivate the MONITORING mode.
The active operation mode is indicated by the LC-display, which will change from L (local / local with signalling “loc sig”) to R (remote) or M (monitoring).

its optimal gain level. Adjust the exciter
output level to achieve a minimum
deviation. Afterwards press “SET GAIN
TO NOMINAL” and, if desired, switch
GAIN CONTROL to AUTO. If a WEEPY is
visible, there is no nominal point set for
the current configuration. Press “SET
