(   ) Install J6 (Pwr) - 3 pin DIN connector on the back of the case. 
       (This will require 2 screws, 2 lock washers and 2 nuts)

(   ) Install J5 (MIC IN) - RCA Plug on the back of the case

(   ) Install J4 (PTT)  - RCA Plug on the back of the case

(   ) Install J2 (MIC IN) - 8 Pin Male Mic Connector on back of case

(   ) Install J3 (MIC OUT) - 5 Pin DIN connector on the back  of the
      case. (This will require 2 screws, 2 lock washers and 2 nuts)

(   ) Install slide potentiometers R15,R16, R17 (100K) and R18 on front            
       panel. Orient potentiometers as shown in Figure 1.
(   ) Install plastic LED holders on front panel.
(   ) Install switch S1 on front panel - Power  switch.
(   ) Install switch S2 on front panel - Noise gate switch. 
(   ) Install switch S3 on front panel - Equalizer on off.
(   ) Install Orange (or yellow)LED  LED3 in holder (as shown in figure 1 .)
(   ) Install Green LED LED1 in holder  (as shown in figure 1 .)
(   ) Install Red LED LED2 in holder (as shown in figure 1.)
(   ) Pre-wire Rotary switch S4 as shown below and install on rear
      of case. The wires going to  J2, J3 and J4  should be cut to 3.5  
      inches. They can be trimmed when the switch is installed in
      the case and wired.  Pre-wiring the switch, with insulated wire,  
      makes wiring it significantly easier. (2 center posts on S4 wired later)
 

(   ) Install the pre-wired switch S4 - Mic Select. Pay attention to         
      the alignment of the switch (per the figure 1). Install the round      
      knob so the center position of the switch has the knob align   
      to K (Kenwood)

ALL PARTS ARE NOW MOUNTED ON THE CASE
