Operating Manual

March 2008 5100 ES Models II/III Portable Radio Operating Manual 5-27
Conventional Mode Features
Sq Adj (Analog Only) - Changes the preset squelch setting on that channel. The default
setting is “0” and values of –7 to +7 can be selected. Increasing this setting toward +7
causes the squelch to open sooner so that weaker signals can be received, and
decreasing it toward –7 causes the opposite to occur.
Note The channel spacing is not set with P25 channels because it is always narrow, and the
squelch cannot be changed because the setting is critical for proper receiver operation.
Chan Spc (Analog Only) - Selects either wide or narrow band channel spacing on
analog channels only. Press the Up/Down switch to select “Wide” or “Narrow”, and
when the desired setting is displayed, store it by pressing the <F2> switch.

ten characters can be entered. Press <F2> once to display the current alias and then
