3 CONTROLS AND INDICATORS
Refer to Figure 1 for the location of the following controls, indicators, and
connections:
3.1 CONTROLS AND CONNECTIONS
qq
POWER SWITCH/VOLUME CONTROL
Turns the transceiver on and off, and adjusts the volume.
ww
SQUELCH CONTROL
Sets the point at which random noise on the channel does not
activate the audio circuits but a received signal does. This point is
called the squelch threshold. Further adjustment of the squelch
control degrades reception of wanted transmissions.
ee
KEY PAD
UP KEY
Selects the desired channel. Each press increases the channel
number. When held down, channels increase continuously.
DN KEY
Selects the desired channel. Each press decreases the channel
number. When held down, channels decrease continuously.
H/L KEY
Toggles between high and low transmitting power. This key does not
operate on “low power only” and transmission-inhibited channels.
When held down while the transceiver is on channel 13 or 67, the
power temporarily enters high range.
WX KEY
Immediately recalls a weather channel 01 from any channel location.
Reverts the transceiver to the previous channel when pressed twice
after 16/9 key is pressed.
