Problem with False alerts

[melbVt]

Good morning fellow forum users,
I'm running four sensors on my car ,

I'm detecting a high # of poliscan alerts too many for the ALP,
Running the latest firmware and using Poliscan false rejection setting ON!
Yesterday I had 3 all up , Anyone else have any issues like this ? REad on please!

Description of false alerts
1 in the dark of night while in my driveway NO chance of real 1 there,
1 in the afternoon as I was turning @ a round about, ( Sun was setting and was bright clear weather,
1 in daytime lunchtime again I was turning and in cloudy weather,

I have been told that if I point my sensors down it may reduce this ( We all know that will decrease performance of ALP not going to even attempt this as the sensors are perfectly level for max performance)
Sensor location Pics attached



This is not the 1st time Ive sent back a cpu or had sensor stop working and my car clearly does not use laser at all as the cruise control is a cable and it's 1998 G.M holden Vt ,

Suggestions anyone ????? Power spike?? Hmmm I'm really confused here !

Thankyou reading I hope this can be fixed without sending back,
