TOPS
To simplify operation and prevent selection of unprogrammed/unused
channels or channel groups, tiny metal inserts or “stops” can be inserted
into the top panel beneath the
CH
selector knob. A tiny tab protruding
from beneath the skirt of the
CH
knob engages the stop(s) as it is turned,
preventing further rotation.
To insert a stop, rotate the
CH
knob to the channel “
1
” position and use
the Allen wrench to
loosen
the setscrew locate the
CH
knob, then pull off
the
CH
knob. Insert the stops firmly into the appropriate slot(s) for the
desired channels, using a pair of tweezers or fine needle-nose pliers, ac-
cording to the drawing below. For example, to limit
CH
selection to chan-
nels 1 - 4, insert one metal stop at the slot 15 (Low channel edge “channel
1”
minus
“two position”), and the other at the slot 3 (High channel edge
“channel 4”
minus
“one position”). When done, press the
CH
selector
knob back on the shaft, align the indicator of the
CH
knob to channel “
1
,”
then tighten the setscrew.
Note
: The use of mechanical stops should not be used or relied upon as the
sole means to prevent selection or transmission on an invalid or unautho-
rized channel. Channels should be locked-out or TX-inhibited via pro-
gramming by your Vertex Standard dealer, and stops inserted as a operat-
ing convenience to you and your network users.
