Stuart,
Can only be one of two things left to check. More than likely you have a
break in the zone loop. A simple check with a volt/ohm meter will verify
that. The other possibility is that your zone is too large for the
transmitter. Maximum wire length is 1,000 feet.
I would check for an open circuit in the loop first by what ever means you
have. If you just have your wire staked down, just check it by running your
hand along it and pulling slightly on the insulation to see if the wire has
broken inside, especially where it has been staked down.

Hi, I bought a Robomower about 5 months ago
(RL-880) and it has been running fine until
now.

The small device that comes with it that you
plug into the zone to activate the circuit
is giving me problems.

I have 4 zones at my house and 3 zones are fine.
You plug it in and the green light happily blinks
on the zone-enabler box (the one with 3 C batteries
inside).

But the other zone, also the largest, has suddenly
decided to stop blinking green and start flashing
the batteries red-light, making it impossible to
mow the backyard. Same unit, same batteries, etc.
that worked on the front yard minutes before. I
take it back to the front yard and it works on all
3 zones.

Anyone know why the battery light on the zone-enabler
can light up preventing a zone from being mowable
but work on all the other zones?

I don't think there's any li cut and I tried two sets
of all fresh C batteries with the same result.

Thanks,

Stuart
