VX-510 OPERATING MANUAL

INSTALLING CHANNEL-STOPS

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 9 o’clock position (slot), and the

other at the 6 o’clock 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 Yaesu dealer, and stops inserted as a operating conve-

nience to you and your network users.
