[time-nuts] Re: Trimble Netrs How do you open it up?

[Bob kb8tq]

Hi

Quick way to take apart a NetRS:

1) Pull out all the screws from the front panel ( the one with the LED’s on it).

2) Pull the screws from the mounting bracket (if it’s still there). All are T10 Torx. 

3) Reverse the Torx driver and use it as a small hammer. Tap the “ears” on 
the front panel. You don’t need to go crazy. It will pop off. 

The D connector on the front panel is normally attached with ribbon cable. 
There is no need to unscrew it. If anything, unscrewing it is a bad idea since
doing so would allow the sub-cabe to the front panel to flex / break. 

Next use a pair of needle nose pliers to unbend the latching strap that holds
the flash card in place. It’s directly above the place the ribbon cable from the 
front panel comes into the main assembly. 

Now you can unplug the flash card and replace it. 

On normal power up, with only power applied ( nothing else attached ). The 
front panel LED’s go through a series of flash flash flash stuff. Eventually they
calm down and you just get a green light showing you which power input you
are connected to.

Normal drill is to just leave the back panel in place. Unless something is broke,
there is no reason to pull it. 

Fun !!
