no berchwood area by the mall
If you are near the mall area near exit 35 on Rt 80 then you should only program in the frequencies for Zone 1 in the database.
Do not program the frequencies for the other 3 zones, unless you are travelling to those areas. If so then set up new systems for each zone. This way, the scanner will only lock on the frequencies nearest you. Otherwise you could be locking onto frequencies that are further away causing your reception issues.
