4.2 RECEPTION
1.Turn the POWER/VOLUME CONTROL knob clockwise to turn the trans- ceiver on.
2.Turn the SQUELCH CONTROL knob fully counterclockwise. This state is known as “Squelch Off.”
3.Turn up the POWER/VOLUME CONTROL knob until the noise or audio from the speaker is at a comfortable level.
4.Select a channel that has no signal being received (no one is transmit- ting on the channel) and where only noise is heard.
5.Slowly turn the SQUELCH CONTROL knob clockwise and stop immedi- ately after the noise disappears. This condition is known as the “Squelch Threshold.” If the knob is turned clockwise past this point, weak signals may not be received. No noise or no signal is heard until a signal is received that exceeds the squelch threshold.
6.To change channels, press the [p] or [q] key. Sometimes, a slight ad- justment of the squelch threshold is needed, as some channels have a higher noise level than others.
7.Please refer to the Owner’s Manual Supplement for a complete listing of all USA, International and Canadian VHF Marine channels and their uses.
8.If necessary, press the LAMP key to turn on the display illumination. The lamp automatically turns off in about 5 seconds. To turn off the lamp sooner, press the LAMP key again.
9.To “lock” the channel so that it is not accidentally changed, hold down the LAMP key for about one second. This locks the [p] and [q] buttons and all the front panel controls except the H/L, PTT and LAMP keys. The “ ” symbol will appear on the display to indicate that the keypad is locked. Hold down the LAMP key for about one second to unlock the keys. The “ ” symbol will disappear from the display.
