Major info are displayed:
- Current channel/group or the receiver name if the MTB40S is
already synchronized with a receiver
- Current frequency (i.e. 520.000 MHz)
- Gain (i.e. AF: -12 dB) and high pass filter (i.e. HP: 120 Hz)
- “RF 10”, “RF 50” or “RF off” on top right if RF transmission is
ON (“RF 10” if the RF power is set to 10mW or “RF 50” if the
RF power is set to 50mW) or OFF

menu
This menu can be entered by pushing
MTB40S can recall configuration presets.
“FACTORY” recalls the Wisycom factory configuration.
“USER” recalls the user configuration (the transmitter configuration
is copied into the USER using the “save to” submenu).
All “USER” menus are not locked by default, thus this is quick way
to unlock features!
When the user changes some parameters from the PRESET
configuration (for less than frequency) a star appears on the topright corner until a save command is executed.
The other 8 configuration presets are user programmable thru the infrared and the PC interface
(using the programmer UPK 300/UPKMini or the receiver MRK950/MRK960).
We provide the device with some preset configurations specifically designed for certain types of
microphone or applications (it’s possible to change these presets in any time using the TX
manager).
All parameters can be “left unchanged”, “changed” or “changed and lock”, allowing a very flexible
way to pre-program MTB40S configuration.
