UNIDEN Model UH400SX,
Operation
Turning on the Power
Press and hold the ON/OFF control at the base or the [POWER] button on the Remote SPK/MIC.
Setting the Manual Squelch (base only)
Turn the outer ring of the SQ control at the base to adjust the Squelch.
You must select a channel which is not in use before setting the SQUELCH control. (see p.19 for “Selecting a Channel”).
Think of the squelch control as a gate. If you turn Squelch fully clockwise it raises the ‘Squelch gate’ so high that no signals get through.
If you turn the Squelch fully counterclockwise it lowers the ‘Squelch Gate’ to the extent that all signals get through - weak, medium and strong signals and noise.
To set the ‘Squelch Gate’ to the desired level, turn the squelch knob counterclockwise until you hear noise. Then carefully turn the Squelch knob clockwise until the noise fades. Now only strong signals get through.
