Safety / Warning Information
WARNING - DO NOT operate the VX-2500 radio when someone (bystanders) outside the
vehicle is within following range.
Safety Training information:
Antennas used for this transmitter must not exceed an antenna gain of 0 dBd. The radio
must be used in vehicle-mount configurations with a maximum operating duty factor not
exceeding 50%, in typical Push-to-Talk configurations.
This radio is restricted to occupational use, work related operations only where the radio
operator must have the knowledge to control the exposure conditions of its passengers and
bystanders by maintaining the minimum separation distance of following range.
Failure to observe these restrictions will result in exceeding the FCC RF exposure limits.
Antenna Installation:
For rear deck trunk installation, the antenna must be located at least following range away
from rear seat passengers in order to comply with the FCC RF exposure requirements.
For roof top installation, the antenna must be placed in the center of the roof.

TRANSMITTING. Press the button programmed for monitoring. Listen for channel
activity.
2. When receiving a call, Transmit only after the incoming call ends. The radio cannot
receive a call and transmit simultaneously.
3. Press the PTT key. When a channel is available, the TXLED will glow red. The radio is
now transmitting and a voice message can be delivered. For best transmission, speak into
the microphone from a distance of 1- 1/2 to 2 inches. Release the PTT key after each
transmission.
4. If Busy Channel Lockout has been programmed for a channel, the radio will not transmit

the PTT key is pressed. Release the PTT key and wait for channel activity to stop.
5. If CTCSS or Digital-Coded Squelch (DCS) Lockout has been programmed for 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.

Understanding Radio Waves
Understanding Radio WavesUnderstanding Radio Waves
Understanding Radio Waves
Radio waves travel from one point to another by several different means. The general term for
these methods of wave travel is “propagation.” You may know that “shortwave” signals can be
propagated over distances of several thousand miles by reflection off of the upper regions of the
atmosphere.
Your hand-held transceiver, on the other hand, operates on the so-called UHF (Ultra-High
Frequency) band. On this band, radio waves usually do not reflect off of the atmosphere.
Instead, the radio waves behave almost as light: they travel in a straight line, and when they
meet a building or obstruction, they go no further in that direction.
Therefore, it is important that you be as high and free from obstructions as possible to cover
the greatest distance when using your radio. If you operate from inside a car or building, any
metal around you can absorb much of the signal, both transmitted and received. Coverage may
therefore be very poor under those conditions. However, if you must operate from indoors,
moving next to a window will improve communications.
In view of the factors just discussed, you can easily see the potential benefit of holding the
radio up high near your mouth while transmitting. In this way the antenna is high and clear,
and coverage is best.
On final note regarding propagation is useful in improving coverage. Because radio waves at
UHF are similar to light waves, they do reflect, to varying degrees, off of hills, buildings, and
the like. In a crowded urban area, with many close buildings close together, many reflections
may occur, and interfere with one another, causing variations in signal strength at different
locations.
Therefore, if a signal is weak and you walk a few feet in any direction, reception may suddenly
become clear, because a particular reflection path may become dominant. Reflections are
frequently useful, as they can allow for communications between two stations over a highly
obstructed path.
