2. Press and hold the SEEK button; while holding SEEK, turn the unit on. Release the SEEK button.
3. Use the Channel UP/DOWN buttons to adjust the squelch sensitivity settings.
4. Squelch setting 00 is no squelch; this effectively disables the squelching capabilities of the
receiver. Squelch setting 20 is maximum squelch sensitivity; you must have a very strong and
stable RF signal for the unit to not engage the squelch feature.
5. Press SEEK to exit the squelch programming mode.
