When initially setting up a VHF transceiver, the correct technique with the squelch and volume controls is to:

• A.Set a comfortable volume, open the squelch until hiss appears, then back it off to silence
• B.Maximise volume first then close the squelch fully to eliminate all background static completely
• C.Adjust volume only — the squelch must remain at its factory preset and cannot be changed
• D.Leave the squelch fully open at all times to ensure no wanted signals are blocked by squelch
