no Enc will appear on the LCD.  To clear: 
1.  Be sure the Encoder is on the Scale and properly oriented. 
2.  Unplug the Encoder from the Digital Readout for one second and 
then reconnect the Encoder. 
3.  Connect the Encoder to the Digital Readout.

 mean? 
When the readout displays this message it means the battery voltage 
has dropped to a level where reliable operation is no longer possible.  
Install new batteries to clear this message.

 mean? 
When the readout displays this message it means the battery voltage 
has  dropped  to  a  level  where  reliable  programming  is  not  possible. 
Install new batteries to clear this message. 
The battery clips seem to be very loose. Is this normal? 
YES!  DO NOT bend these clips or wedge anything between them and 
the  case.    These  clips  are  designed  to  expand  when  the  two  case 
halves are screwed together. 
The Digital Readout numbers appear to be random. (Model 150 & 250 only) 
Be sure the Encoder is oriented correctly on the Scale. One end of the 
Scale  is  marked  in  black;  be  sure  that  the  arrow  on  the  Encoder  is 
pointed in this direction. 
The Digital Readout does not change, or changes very little, as the Scale 
or Encoder moves. 
1.  The Digital Readout is in the HOLD mode. 
2.  The Encoder is on the Scale backwards. 
3.  The Scaling factor is set very low. 
The Digital Readout alternately shows “no Co
no Cono Co
no Co”. 
The digital readout has non-linear accuracy compensation firmware 
and the position of the encoder is outside the programmed calibrated 
operating range OR the system datum has been changed.  Move the 
encoder  to  a  position  within  the  calibrated  range  and make  sure  the 
system datum is set properly.
