19 Basic Radio Operation (cont.)
Transmitting
Conventional Modes
1. Turn the radio on and select the desired zone and
mode (see “Selecting a Zone and Mode”).
2. (SECURENET-equipped radios only). If the mode is
programmed as neither secure-only nor clear-only,
turn the two-position concentric switch to the
d e s i r e d p o s t i o n ( = S E C U R E N E T v o i c e
transmission; = clear voice transmission).
3. Listen for a transmission and adjust the volume
control for a comfortable listening level. Refer to
step 2 of “Conventional Modes,” “Receiving a Call.”
4. Do not interrupt another user. If the mode on
which you are transmitting is programmed to
receive PL ( or the proper code if SECURENET-
equipped), ensure that the mode is not in use by
momentarily depressing the monitor button to
listen for activity. If the mode-busy feature is
enabled, a blinking red LED on receive (PTT
released) will indicate that the mode is currently
busy and you should not transmit.
Note: The mode-busy feature is suggested for
SECURENET-equipped radios, since monitoring of
SECURENET activity with a different key will sound
like noise that is nearly indistinguishable from
channel noise.
5. When the mode is clear, press and hold the PTT
switch on the side of the radio and speak slowly
and clearly into the microphone area. The red LED
w i l l b e l i t c o n t i n u o u s l y w h i l e t h e r a d i o i s
transmitting. When you have finished talking
(transmitting), release the PTT to listen (receive).
Notes:
• If a mode is programmed for receive only, any
attempt to transmit on that mode will cause
an invalid-mode tone to sound until the PTT
switch is released.
• To take full advantage of the noise-cancelling
feature, avoid blocking the noise-cancelling
port during transmitting.
