The  plastic  housings  of  the  ACl  and  ADl 

bases  are  secured  by captive  housing  screws 

located  behind  the  number  card  and  number  card 

retainer.  To  remove  the  housing  from  either  base 

assembly use a KS-16750 type releaser or equivalent 
to  remove  the  number  card  retainer  (Fig.  6). 

Be 

careful  not  to  insert  the  tip  of  the  releaser  too 
deep  or  mar  the  base  housing. 

Loosen  the  two 

captive  screws,  which  are  now  exposed,  and  lift 
the housing off.
