Onwa Marine Electronics KV-300 - Manual (Page 15)

5.1 Turning KV-300 on/off
To turn the transceiver on, rotate the PWR/VOL knob clockwise until it clicks on.
You will hear a beep(acoustic signal)and the LCD display will show the channel
in use.
Important: when you turn on the radio for the very first time, the display will
show channel 16; while usually, KV-300 stores the last channel in use before it's
switched off. To turn the transceiver off, rotate the knob counter-clockwise until
you hear a click.
5.2 Volume adjustment
Bring the OFF/VOLUME knob first to medium volume.Once the transceiver picks
up a signal, adjust the volume t o a comfortable level. If no signal is picked up,
use the squelch control as described in the following paragraph and regulate the
volume using the background noise.
5.3 Squelch Regulation
Squelch is used to eliminate the annoying background noise you hear when no
signal is being picked up. If the squelch is adjusted correctly, there should be
silence in between calls as well as a reduction in battery consumption. To regulate
the squelch:
1. Rotate the SQUELCH knob completely counter-clockwise until you hear the
background noise (if you don't hear anything, increase the volume); RX
will appear on the display.
2. If no signal is being received (only noise), slowly rotate the SQUELCH
knob clockwise,stopping as soon as the noise and RX disappear stably.
If you regulate the squelch level too high (closed), you may hear only
background noise or intermittent discharges.
5.4 Selecting an operating channel
Press repeatedly the UP or DOWN buttons on the keypad or on the microphone
to scroll through the marine channels until finding the desired channel.
Channel 16 is dedicated to the emergencies, therefore we recommend not to use
it for general communications!
Channel 70 is dedicated to DSC communications.
