9 CONTROLS AND INDICATORS
NOTE
This section defines each control of the transceiver. See Figure 4 for
location of controls. For detailed operating instructions refer to section
“10 BASIC OPERATION.”
VOLUME CONTROL (VOL)
Adjusting this control clockwise, increases the audio volume level.
SQUELCH CONTROL (SQL)
Adjusting this control clockwise, 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 will degrade reception of wanted transmissions.
MICROPHONE CONNECTOR
Connect the supplied MH-63A6 Hand Microphone to this jack.
KEY BUTTON
[16/9] Key
Immediately recalls channel 16 from any channel location. Holding down
this key recalls channel 9. Pressing the [16/9] key again reverts to the
previous selected working channel.
Secondary use
Press and hold the [16/9] key then press the [WX] key to switch the
Channel Group.
[WX] Key
Immediately recalls the previously selected NOAA weather channel from
any channel.
Secondary use
Holding down the [16/9] key while pressing the [WX] key changes the
Channel Group.
[H/L] Key
Toggles between 25 W (High) and 1 W (Low) power. When the [H/L] key
is pressed while the transceiver is on channel 13 or 67, the power will
temporarily switch from LO to HI power until the PTT is released.
The [H/L] key does not function on transmit inhibited and low power only
channels.
