TOPS
To simplify operation and prevent selection of unpro-
grammed/unused channels or channel groups, tiny met-
al 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 pli-
ers, according to the drawing below. For example, to lim-
it
CH
selection to channels 1 - 4, insert one metal stop at
the slot 16 (channel 1
minus
“one position”), and the other
at the slot 3 (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 unauthorized channel.
Channels should be locked-out or TX-inhibited via pro-
gramming by your Vertex Standard dealer, and stops in-
serted as a operating convenience to you and your net-
work users.
