*Note: Menu entries are visible dependent on device configuration or mode.
Squelch: The Squelch setting is only valid in direct mode. Squelch is used to separate white
noise from actual transmissions, by adjusting the receive trigger level. Increasing squelch will
block white noise and weak transmitters, while reducing the squelch will let weaker
transmitters through. The actual setting of squelch is dependent on the operational
environment. The setting is persistent over a power off-on cycle.
Note: The Squelch menu is only visible when the MP50 is in direct mode.
Audio Feedback: The volume of the audio feedback can be set. Setting the volume to zero
will disable audio feedback. The setting is persistent over a power off-on cycle.
Headset: By default, the MP50 will detect the connected microphone type. It is possible to
override this and set the microphone type to be unamplified or amplified electret, custom or
low impedance dynamic mic. The setting is persistent over a power off-on cycle.
Mic Equalizer: For best possible sound quality for those receiving your transmission, it is
possible to adjust the treble of your transmission. It is possible to choose either flat, soft or
sharp. When choosing the best treble setting, a headset connected directly to the intercom
should be used for evaluation of your transmission. The preferred choice can differ when
changing microphone or windsock. The setting is persistent over a power off-on cycle.
Speaker Equalizer: For best possible sound quality when receiving transmissions, it is
possible to adjust the treble of the received transmission. It is possible to choose either flat,
soft or sharp. When choosing the best treble setting, a transmission from either another
MP50 or a headset connected directly to the intercom can be used. The setting is persistent
over a power off-on cycle.
VOX Maximum Level: When the VOX trigger level increases because of ambient noise, the
trigger level can never pass the VOX maximum level, even if the ambient noise indicates that
a higher trigger level should have been used. The setting is persistent over a power off-on
cycle.
VOX Minimum Level: The equipment is by default set to minimum VOX level when VOX
mode is entered. The VOX trigger level will increase as the environmental audio conditions
force the level up. The setting is persistent over a power off-on cycle.
Display Intensity: Display illumination intensity can be regulated in steps between 1-9. The
setting is persistent over a power off-on cycle. At start up the programmed default intensity is
used, and then gradual adapting to the user selected intensity over a few seconds.
Display Rotate: This menu is only present if the functionality is enabled in the active
configuration. Select which orientation to read the display. Normal setting is to read display
from the front of the device. The other direction is typically used for reading the display while
the device is located in the breast-pocket. The setting is persistent over a power off-on cycle.
GPS Enable: Enable/disable GPS position polling. Minimum rate for position update to base
station is affected by the amount of active GPS reporters. Few active GPS reporters will
shorten the time between position reports. The setting is persistent over a power off-on cycle.
