System Op er a tion
Fre quency Plan Over view
The WBS/WTR-680 has 36 fac tory-defined fre quency groups
and 12 user-programmable fre
quency groups. A Group de -
fines the two base-station trans mit fre quen cies and thus the
two re ceive fre quen cies on all the beltpacks. A Chan nel de -
fines a base-station re
ceive fre quency and thus a beltpack
trans mit frequency. A base-station re ceive chan nel that does
not have a fre quency set for it will have a dash to the right of
it on the Group/Chan nel se lect screen. De tails on set ting fre -
quen cies may be found in the “WBS-680 Menu Struc ture” and
“WTR-680 Menu Struc ture” in struc tions in this sec tion.
Fac tory-Defined Groups
The 36 fac tory-defined groups were care fully cho sen to avoid
cer tain intermod prod ucts and var i ous other pos si ble sources
of in ter fer ence. The Groups are set and can not be changed. A
lim ited num ber of chan nels can be chosen from within these
groups.
The first 24 factory-defined groups (01A – 12B) are “pair”
groups that can be used for sin gle (up to 4 beltpacks) and dual
(up to 8 beltpacks) WBS-680 sys
tems. They are ar ranged
01A, 01B, 02A, 02B…011B, 012A, 012B. A “pair” group,
like 1A and 1B, have dif fer ent base-station transmit fre quen -
cies, how ever, they both have the same eight base-station re -
ceive chan nels from which to choose. Each chan nel rep re sents
a unique fre quency. For ex am ple, one WBS-680 could be set
on Group 02A and chan
nels 01, 02, 03 and 04. The other
WBS-680 could be set on Group 02B chan nels 05, 06, 07 and
08. As long as the chan nels are dif fer ent, everything should
be fine.
The next 12 groups (13 – 24) are sin gle groups that primarily
are used for sin gle (up to 4 beltpacks) WBS-680 sys tems. The
num
ber of chan nels from which to choose from in these
groups will vary from group to group.
User-Programmable Groups
The 12 user-programmable groups are ini tially empty. The
trans mit and re ceive fre quen cies are fully editable within these
groups. In fact, fac
tory-defined groups may be cop ied to
user-programmable groups and then ed ited if de sired. See the
“WBS-680 Menu Struc ture” and “WTR-680 Menu Struc ture”
in struc tions in this sec tion for de tails on how to copy and edit
fre quen cies.

level con trols in the 12 o’clock po si tion. Check that
front-panel IC A and B is in 2-wire for Clear-Com,
AudioCom® (Telex), and RTS - TW wired sys tems, and
4-wire for ma trix and stand-alone op er a tion.

7. Re move the rear switch cover on the beltpacks. Set the
beltpack rear-panel slide switch to push-to-talk (PT
