Internal Controls
Speaker Level- Local Control
A post header, P14, has been provided for adjustment of the speaker volume. The speaker volume
adjustment operates as follows:
• The initial direction of the volume (increase or decrease) is determined by prior activity. The initial
direction will be opposite to that of the previous activity.
• Changing the direction is accomplished by allowing a period of inactivity (open across P14) for
greater than 1 second or by moving the wiper to the end of the potentiometer range.
Example /Volume Increase: Short across P14. The volume begins to decrease. Remove short across P14
and wait 1 second. Short across P14 again. The volume begins to increase. Remove short across P14
when the desired volume has been reached.
P14 can also be used as an optional front panel volume control switch.
Speaker Level- Remote Control
The speaker volume level can also be controlled remotely by changing the setting in the configuration
file. Please refer to the Speaker Volume section of Pub. 42004-396 for programming instructions.
N
OTE : The local speaker volume setting using P14 should be set for the maximum volume (factory
default) prior to adjusting the speaker volume remotely.
