Pin settings and labelling
Users can create custom labels for the: microphone/line 
inputs, description of the music sources, and audio 
output zones 1 and 2. These labels can be attached to 
the mixer amplifier at position numbers 2 and 3 (see 
figure 2.2). Colored pins can 
also be inserted at various 
positions around the dial controls to indicate the favorite 
settings for a particular application.
The pins are engineered in such a way that they cannot 
be taken out by hand. This is to prevent tampering. The 
pins are intended to be inserted once, during installation 
of the unit. The silver pins should be used to indicate 
the preferred settings of the unit. The red pins can 
optionally be used to indicate the maximum setting of a 
knob. 
If these settings have to be changed, use a pair of soft-
tipped pliers to carefully remove the pins. If you do not 
have a pair of soft-tipped pliers, you can use ordinary 
pliers instead, but first place some plastic tape on the 
tips of the pliers to prevent damaging the front of the 
unit.
 
To remove the clear plastic covers in front of the labels:
1 Carefully insert a small screwdriver into the cut-out 
at the bottom of the plastic cover.
2 Gently lift the cover, and bend it in the middle. Take 
care not to force the cover or the front panel.
To reattach the plastic covers with paper labels:
1 Insert the paper label into the holder at the front of 
the unit.
2 Pick up the cover, and then bend it slightly in the 
middle by hand. 
3 Fit the cover into the slot at the front of the unit, and 
then gently release the cover, making sure that the 
paper label stays in place.
