sr7 comm interface error

**Jammer84_03** · 03-19-2008, 12:52 PM

i was looking to get a used sr7. found one with an error message that is a comm interface error. is it the main control box thats gone bad, or a sensor? is that fixable by escort?

It's probably fixable, not sure what they would charge to fix it.

check the power source. i've seen a similar error come up if the supply voltage is low, or has a large drain on it, meaning too many things tapped into the same power source. maybe try connecting to the battery to see.

make sure the display unit is plugged into the right connector on the control box.
disconnect any laser receiver heads and see what it does.
on the SR7plus it will display an error about no receiver connected, but then continues normally.

double check the radar receiver connection.

if the optional remote mute or remote LED are plugged in, unplug them, to rule that out.

if that still doesn't work, it sounds like repair time. :?

I know this is late, and I apologize - I've been very busy lately, and haven't been able to frequent this Forum.

ops:

84_03, give Escort Tech Support a call, and be as descriptive as possible with your problem, as well as what you've done to try to solve it.

They should be able to give you an estimated cost of repair/replacement.

yea, you don't want to send it in, if it's not from authorized dealer they'll take it. it's most likely a short in the wiring from one of the laser heads or the radar antanna, try putting a toner on the components and find where the short is, then you can just cut it, strip it and replace it with phone cableing.

:?: :?: :?: :roll:

No, this is not the case.

I got my ZR3 from an "unauthorized reseller" off of eBay. And yes, I sent my unit in for repairs.

No, they will NOT "take" your unit.

It'll just be an out-of-warranty repair.

Did you buy it? I know the stuff for the SR7 is expensive (compare to V1 at least). They wanted $180 for an extra display, good thing I didn't screw that up.
