I think you mean Z60. Normally...most scanners...there is a "PROG" or program button...hit that first...then input the frequency you want..and hit Enter.
The "search" button will run throught the pre-programed freq. I'm guessing.
Found this:
Z60: base/mobile sporting 60 channels, but 10 of them are
for FM broadcast only. Built in alarm clock, priority, and
memory which requires no battery backup.
Covers
30 - 50
88-108 radio FM
118-136
144-174
440-512 MHz.
Notice that it's not spec'd to cover some important federal bands: 136 - 144 and
406 - 440
