I would like to replace my JT1000 in the future with a HT1550xls but I have some scan list ,zone questions. I have been told that the CDM/HT1550 will scan up to 99 channels but when you use the assignment wizard you can put 99 in the zone and only 16 in the scan list. I have played with my CDM1250 ,1 zone with 32 channels with 2 scan lists of 16 each and it will only scan 16 at a time. Would the CDM1550 and HT1550xls all 32 channels ?

no more than 16ch at a time
