OPERATION
The Channel Announcement Feature works as described below
(1) In the VX-454/459 radio:
The maximum number of channels is 512 (32 channels maximum per group). The radio announces the
channel number digit by digit.
For example, “Channel 1” is announced as “one” and “Channel 10” is announced as “one zero”.
(2) In the VX-451 radio:
The maximum number of channels is 32 (16 channels maximum per group). The radio announces
Channels 1 - 9 by digit, while Channels 10 - 16 are announced by number.
For example, “Channel 10” is announced as “ten” and so on.

If a Speaker/Microphone
is available, remove the
plastic cap and its two
mounting screws from
the right side of the trans-
ceiver, then align the con-
nector of the Speaker/
Microphone on the trans-
ceiver body; secure the
connector pin using the screws supplied with the

2) When you press the PTT switch on the
Speaker/Microphone, it disables the internal mi-
crophone, and vice versa.
If the Busy Channel Lockout feature has been
programmed on a channel, the radio will not trans-
mit when a carrier is present. Instead, the radio
will generate short beep three times and indicate
“CH BUSY” on the display (VX-454 and VX-
459). Release the PTT switch and wait for the
channel to be clear of activity.
If CTCSS or Digital Coded Squelch (DCS) Lock-
out has been programmed on a channel, the radio
can transmit only when there is no carrier being
received or when the carrier being received in-
cludes the correct CTCSS tone or DCS code.
Automatic Time-Out Timer
If the selected channel has been programmed for au-
tomatic time-out, you must limit the length of each
transmission. While transmitting, a beep will sound
10 seconds before time-out. Another beep will sound
just before the deadline; the “TX” indicator will dis-
appear and transmission will cease soon thereafter.
To resume transmitting, you must release the PTT
switch and wait for the “penalty timer” to expire.
