The BCLO feature prevents the radio's transmitter from being activated if a signal strong
enough to break through the "noise" squelch is present. On a frequency where stations
using different CTCSS or DCS codes may be active, BCLO prevents you from disrupting
their communications accidentally (because your radio may be muted by its own Tone
Decoder). The default setting for the BCLO is OFF, and here is how to change that setting:
1. Press and hold in the [ MHz ( SET )] key for one second, then
rotate the DIAL knob to select "5 BCLO."
2. Press the [ MHz ( SET )] key momentarily to enable adjustment of this Set Mode Item.
3. Rotate the DIAL knob to set this Set Mode Item to "
(thus activating the BCLO feature).
4. When you have made your selection, press and hold in the [ MHz ( SET )] key for one
second to save the new setting and exit to normal operation.
Remember that BCLO is controlled by the Noise Squelch; if you have DCS or
TSQ engaged, BCLO will inhibit transmission if a station is on frequency but not
transmitting the proper tone; BCLO will thus prevent you from interfering with the other
station's transmission.
