NOTES:
1.
These settings are not to be used in UL Listed applications
and should be used in non-UL Listed applications only when
the audio input level is not at the rated value – 0.5 V RMS for the 0.5-V mode and 25 V RMS for the 25-V mode – to
provide 3- or 6-dB compensation for line losses and/or low drive levels.
Using these settings while applying the rated audio
input to the appliance will cause excessive distortion and increased current consumption, and it is not a recommended
operating condition.
2.
This is the setting used as a reference level for the other settings in this table.
3.
These are
typical
values with respect to the reference level (Sound Output Level 6: 0 dB), and are included only to assist the
user in choosing a setting during installation.
However, use the values in Table 1, not these values, for the actual sound
output levels.
WARNING: DOUBLE CHECK SWITCH (SW1) SETTINGS TO MAKE SURE THEY ARE CORRECT.
IMPROPER SETTINGS CAN DAMAGE THE UNIT OR RESULT IN A DISTORTED OUTPUT OR A dBA SOUND
OUTPUT LEVEL THAT IS BELOW CODE REQUIREMENTS FOR PUBLIC MODE FIRE PROTECTION, WHICH
COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.
