INTRODUCTION
For North American Users Regarding 406 MHz Guard Band
The U.S. Coast Guard and National Oceanographic and Atmospheric Admin-
istration have requested the cooperation of the U.S. Federal Communications
Commission in preserving the integrity of the protected frequency range 406.0
to 406.1 MHz, which is reserved for use by distress beacons. Do not attempt
to program this apparatus, under any circumstances, for operation in the fre-
quency range 406.0 - 406.1 MHz if the apparatus is to be used in or near
North America.
The VX-2500 Series are full-featured FM transceivers designed for flexible mobile
and base station business communications in the VHF or UHF Land Mobile bands.
These transceiver are designed for reliable business communications in a wide vari-
ety of applications with a wide range of operating capability provided by their lead-
ing-edge design.

transmitting. While holding in the PTT switch, speak across the face of the mi-
crophone in a clear and normal voice. For best transmission, hold the microphone
about 1-1/2 to 2 inches away from your mouth. Release the PTT switch to re-
ceive.
If the Busy Channel Lockout feature has been programmed on a channel, the
radio will not transmit when a carrier is present. Instead, the radio will generate a
continuous low-pitched tone while the PTT switch is pressed. Release the PTT
switch and wait for the channel to be clear of activity.
If CTCSS or Digital Coded Squelch (DCS) Lockout has been programmed on a
channel, the radio can transmit only when there is no carrier being received or
when the carrier being received includes the correct CTCSS tone or DCS code.

VX-2500 OPERATING MANUALPage 6
Automatic Time-Out Timer
If the selected channel has been programmed for automatic 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 “ ” indi-
cator will disappear and transmission will cease soon thereafter. To resume transmit-
ting, you must release the PTT switch and wait for the “penalty timer” to expire (if
you press the PTT switch before this timer expires, the timer restarts, and you will
have to wait another “penalty” period)

25 seconds (the interval is programmed by the Dealer) in an attempt to shake hands
with the other station.
If you move out of range for more than two minutes, your radio senses that no signal
has been received; a ringing beeper will sound, and “OUT OF SERVICE” will scroll
on the LCD. If you subsequently move back into range, as soon as the other station
transmits, your beeper will sound, and “IN SERVICE” will scroll on the LCD.
DTMF Paging System
This system allows paging and selective calling, using DTMF tone sequences.
When your radio is paged by a station bearing a tone sequence which matches yours,
your radio’s squelch will open and the alert ringer will sound. The three-digit code of
the station which paged you will be displayed on your radio’s LCD.
