Equipment Settings
Default value: Trigger Alarm
Volume
The
MINIMUM VOLUME
and the currently selected
VOLUME
for the loudspeaker in the
main unit can be edited. The
MINIMUM VOLUME
is the lowest level the volume can be
set to from the main display and should prevent unintentional turning off of the main
unit audio alarms. Both values will also be valid for the headphones outlet. Both
volumes (minimum and current) can be chosen between 0 and 15.
Default value for minimum volume: 2
Default value for the current volume: 2.
4.4.3 Display Settings
In the
DISPLAY SETTINGS
submenu the contrast of the display can be changed and the
peak hold function can be set-up.
Contrast
In the
CONTRAST
submenu the contrast of the main unit display can be adjusted.
Values between 0 and 99 can be entered. Also the display can be switched to
inverted colours.
Default value: not inverted, Level 30
Notice
If by accident the display contrast has been set too high or too low so that
it cannot be read off anymore, this can be fixed as follows: Shut off the
Protec P3000 and switch it back on. During run-up press the third button
from the top on both sides of the display simultaneously until the contrast
is back to normal. This setting is not saved to the EEPROM but needs to
be confirmed manually through the contrast menu. Otherwise the Protec
P3000 will go back to the out of range setting after the next start-up.
Hearing damage from excessively loud signals
The volume of signals can exceed 85 dB(A).
Keep away from the device if the volume has been set to high.
Wear ear protection, when needed.
