Radio Shack HTX-242 Setting Volume and Squelch, Using the Light, Setting the Power Level

Setting Volume and Squelch

SQUELCH sets the minimum signal level that must be present for the HTX-242 to amplify the signal through the speaker or to stop when scanning. Follow these steps to set the squelch.

1.Rotate SQUELCH fully counterclockwise.

2.Set VOLUME so you can hear the background hiss between transmissions.

Note: If you do not hear hissing, turn TUNE/M-CHto select a frequency that does not have communications in progress.

3.Slowly turn SQUELCH clockwise until the hissing stops.

If you turn SQUELCH too far clockwise, you might miss parts of transmissions. If you do not turn SQUELCH far enough clockwise, you hear hissing between transmissions and the HTX-242 might not scan properly.

Using the Light

Your HTX-242 has two display light levels. To switch between the two levels, press F then DIM.

Setting the Power Level

Your HTX-242 has two transmit power levels. Low is about 10 watts, and high is about 45 watts. To switch between the two power levels, press LOW. LOW or HIGH appears on the display. The power setting is saved when you store settings in memory.

Locking the Controls

To lock the controls on the microphone (except the push-to-talk button, PTT), slide LOCK ON to the right. This does not lock the HTX-242’s front panel controls.

To lock all controls except POWER, VOLUME, SQUELCH, and the push-to-talk button, press F then LOCK. LOCK appears on the dis- play.

To unlock the controls, press F then LOCK again.
