ON/OFF, VOLUME
• The "ON"/LOW BATTERY INDICATOR (Figure 2) is used
to indicate: power, low batteries or sleep mode. Refer to
flash codes chart on the next page.
• The stereo headphone jack accepts either stereo or
mono headphones or earphones.
• The adjustable squelch (Figure 1) can help reduce
user fatigue by turning off the audio when the signal
becomes weak. If the operator is annoyed or fatigued
by noise, turn the squelch up. This will reduce the
effective range of the receiver as a trade-off to listener
comfort. Similarly if the operator needs more range and
can tolerate the noise, turn the squelch down*.
To adjust the squelch: using a small screwdriver, turn the
knob to the right for more squelch; left for less squelch.
