1.10.  Opening the Front Cover - Regenerating the Desiccant Plug  

The CCD is housed in a sealed chamber located 

inside the front cover of the camera.  The 

chamber is separate from the large front and rear 

cover plates, so that opening the front or rear 

cover plates will not expose the CCD chamber to 

the environment.  The CCD chamber has a 

desiccant plug located on one side to help 

remove moisture from the air inside the 

chamber.  If it should become necessary to 

recharge the desiccant due to excess moisture or 

frosting in the chamber, it is a simple matter to 

remove the desiccant plug, bake it in a 

conventional oven at 350 degrees F (175 degrees 

C) for 4 hours and replace the plug in the camera.  To gain access to the desiccant plug, remove 

the front cover by loosening the eight socket head screws as shown in the picture above left.  

Note the location of the desiccant plug (A) in the 

next photo below right.  Remove the plug by 

unscrewing the two socket head screws (B) holding 

it to the chamber.  There is an o-ring between the 

plug and the chamber.  Be sure to remove this o-

ring before baking the plug. Place a small piece of 

electrical tape over the hole in the side of the CCD 

chamber while you are baking the desiccant plug to 

keep unwanted dust and moisture out of the 

chamber.   When you replace the desiccant plug 

after baking it, remember to replace the o-ring.   

1.12.  Indicator Lights 

There are two sets of LED indicator lights located on the side of the camera body that provide 

information about the camera’s communication link, exposure status, relay activity, and input 

voltage.  The top row contains five LEDs:  

The red status LED will flicker when the 

camera is powered up.  It will then either glow 

continuously when the camera is idle or blink 

when the camera is taking an exposure.  The 

four amber LEDs indicate when any of the 

four relays are activated during during self-

guiding.  The bottom row contains four LEDs:  

These indicate the input voltage to the camera 

and are helpful when operating from battery 

power.  Normally the Green LED will glow 

continuously to indicate that the power 

supplied is 12 -14 volts.  The first yellow LED labeled 11V will light if the input voltage at the 

camera drops to 11.25V or less.  The second yellow LED labeled 10V will light if the input
