To expand the transmit frequency coverage, hold down F+DTMF while
you turn on the HTX-212. The new frequency ranges are:
VFO* Mode:
Memory Channels:
* VFO (Variable-Frequency Oscillator) modes let you scan or select any
frequency within the range.
Note: To return to the default frequency ranges, you must reset the trans-
ceiver. See "Resetting the HTX-212" on Page 17.

SETTING VOLUME AND SQUELCH

SQUELCH sets the minimum signal level that must be present before the
HTX-212 amplifies the signal through the speaker. Follow these steps to
set the squelch to a reasonable setting.
1. Rotate SQUELCH fully counterclockwise.
2. Set VOLUME so you can hear the background hiss between trans-
3. Slowly turn SQUELCH clockwise until the hissing stops.
If you turn SQUELCH too far clockwise, you might miss parts of transmis-
sions. If you do not turn SQUELCH far enough clockwise, you hear hissing
between transmissions and the HTX-212 might not scan properly.

USING THE LIGHT

Your HTX-212 has two display light levels. To switch between the two lev-
els, press F then DIM.

SETTING THE POWER LEVEL

Your HTX-212 has two transmit power levels. Low power is about 10
watts, and high power is about 45 watts. To switch between the two power
levels, press LOW. LOW or HIGH appears on the display.
