Push [MONI] to close the squelch.
w Set the squelch level.
Rotate [SQL] fully counterclockwise in advance, then
rotate [SQL] clockwise until the noise just disappears.
• When interference due to strong signals is received, rotate

the transceiver temperature becomes extremely high, the
transceiver reduces transmit output power to 5 W
automatically.
