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 will degrade the reception of wanted transmissions.
ee
TX/BUSY LED
Lights RED to indicate that the Push-To-Talk switch is pressed.
Lights GREEN to indicate that the selected channel is busy during
reception.
rr
PUSH-TO-TALK (PTT) SWITCH
Activates transmission.
tt
UP KEY
Selects the desired channel. Each press increases the channel
number. When held down, the channels increase continuously.
yy
DOWN KEY
Selects the desired channel. Each press decreases the channel
number. When held down, the channels decrease continuously.
uu
16/9 KEY
Immediately recalls channel 16 from any channel location. Holding
