Please note that the ones/tens digit encoding, shown by “x” and “y”, reverses position for
each 100 pager block. In GE/Motorola plans, first tone is always tens digit, and second tone
is ones digit.
For a REACH group call, 0xx group is not present. Instead, ten group calls are accessible
using pager numbers 000,011,022, ... 099, that generate the ten group call tones from tone
group Z1. The group calls activate 1st tone Z1 pagers (cap codes 1xx, 5xx, and 7xx).
