The MEMO/M.PRG, SCAN/DUAL, BAND/HI/LO, and LIGHT/LOCK
buttons are dual-function buttons. The primary function is printed
above, and secondary function is printed below.
TURNING THE UNIT ON/OFF
Rotate the PWR/VOLUME knob clockwise until it clicks to turn the
unit on. To turn the unit off, rotate the knob counter-clockwise until
it clicks.
SELECTING A BAND
Three bands are available on the VHF5 - USA, International and
Weather. The USA band are frequencies for use in US boundaries. The
International band are frequencies for use outside US boundaries. The
Weather band monitors NOAA/Canada weather broadcasts. To switch
between bands, press the BAND/HI/LO button until the desired band
is reached. The band in use is indicated on the LCD by USA, INT or
WX. When tuned to the WX band and the active weather channel for
your area, the VHF5 will sound NOAA Weather Alert tones as they
are received. Note: The VHF5 will sound NOAA Weather Alert
tones even when the volume is turned down. You must turn
volume up to hear specific weather alerts for your area.
SELECTING A CHANNEL
Select the appropriate band - USA, International or Weather. Once
the band is selected, rotate the CHL/SQL knob either clockwise or
counter-clockwise to scroll through the available channels. Note: Not
all channel numbers are available in all bands. Certain channels
are receive only, while others transmit and receive on different
frequencies (not duplex channels). Additionally, several chan-
nels broadcast on LOW power only. See Table of Marine
Channels for detail.
TRANSMITTING A CALL
The PTT (Push-To-Talk) button is located on the side of the VHF5.
Before transmitting, make sure the channel is not a “receive-only”
channel. To transmit a message press and hold the PTT button. Talk
clearly into the speaker/microphone area of the radio. When finished,
release the PTT button. During a transmission, TX appears on the
LCD. Note: while transmitting a message, the radio can not
receive a call.
