IMPORTANT:
When Silent mode is enabled on a channel,

Busy Lockout
To help prevent accidental transmissions over the top
of other users, the TX3500S incorporates a Busy
Lockout feature.

your CTCSS/DCS group are transmitting on the channel
and prevents your radio from transmitting over them. If the
channel is busy and you press the PTT the radio will emit a
warning beep and the
you release the PTT, look for the
an indicator that the channel is in use. If the channel is busy,
simply wait until the channel is clear and press the
PTT again.
NOTE:
You can also press the Monitor key to open the
Squelch and listen for signals on the channel before
transmitting (see Monitor Function directly below).
