ADVANCED OPERATION
Description of Operating Functions
Channel Scan
The Scanning feature is used to monitor multiple
channels programmed into the transceiver. While
scanning, the transceiver will check each channel for the presence of a signal, and will stop on a
channel if a signal is present.
One key or switch may be assigned to the Scan
function, as follows:
r One of the Soft keys may be assigned for
Scan operation; or
r The TOGGLE switch may have one position
assigned to the Scan function.
To activate scanning:
¦ Press the assigned Soft key, or set the
TOGGLE switch to the assigned position.
The
scanner will search the channels, looking
¦
for active ones; it will pause each time it finds
a channel on which someone is speaking.
To stop scanning:
¦ Press the assigned Soft key, or set the
TOGGLE switch to a different position.
¦ Operation will revert to the channel to which
the CH knob is set.
10
Note: Your dealer may have programmed your
radio to stay on one of the following channels if
you press the PTT switch during scanning pause:
£ Current channel (“Talk Back”)
£ “Last Busy” channel
£ “Priority” channel
£ “Home” channel
£ “Scan Start” channel
Dual Watch
The Dual Watch feature is similar to the Scan feature, except that only two channels are monitored:
r The current operating channel; and
r The “Priority” channel.
To activate Dual Watch:
¦ Press the assigned Soft key, or set the
TOGGLE switch to the assigned position.
¦ The scanner will search the two channels; it
will pause each time it finds a channel on
which someone is speaking.
To stop Dual Watch:
¦ Press the assigned Soft key, or set the
TOGGLE switch to a different position.
¦ Operation will revert to the channel to which
the CH knob is set.

ADVANCED OPERATION
Low Power
Press the assigned Soft key or switch the
TOGGLE switch to the assigned position to set
the radio’s transmitter to the “Low Power” mode,
thus extending battery life. Press the assigned
Soft key again or switch the TOGGLE switch
to the other Position to return to “High Power”
operation when in difficult terrain.
Talk Around
Press the assigned Soft key or switch the
TOGGLE switch to the assigned position to activate the Talk Around feature when you are operating on duplex channel systems (separate receive and transmit frequencies, utilizing a “repeater” station). The Talk Around feature allows
you to bypass the repeater station and talk directly
to a station that is nearby. This feature has no effect when you are operating on “simplex” channels, where the receive and transmit frequencies
are already the same.
Note that your dealer may have made provision
for “Talk Around” channels by programming “repeater” and “Talk Around” frequencies on two
adjacent channels. If so, the key may be used for
one of the other Pre-Programmed Functions.
VX-900U OPERATING MANUAL
TX Save Disable
Press the assigned Soft key or switch the
TOGGLE switch to the assigned position to disable the Transmit Battery Saver, if you are operating in a location where high power is almost always needed.
The Transmit Battery Saver helps extend battery
life by reducing transmit power when a very
strong signal from an apparently nearby station
is being received. Under some circumstances,
though, your hand-held radio may not be heard
well at the other end of the communication path,
and high power may be necessary at all times.
LCD Invert
Press the assigned Soft key or switch the
TOGGLE switch to the assigned position to invert the LCD display to backward-facing readout
(the backward display is convenient for viewing
when wearing the transceiver on your belt). Press
the assigned Soft key again or switch the
TOGGLE switch to the other position to return
the LCD display to frontward-facing readout.
11
ADVANCED OPERATION
Encryption Disable
Press the assigned Soft key or switch the
TOGGLE switch to the assigned position to turn
off the optional voice encryption unit temporarily,
for use when an incorrect setting of (or failure in)
the encryption system at one end of the communication path has made it impossible to talk to the
other station.
Remember that disabling the encryption will mean
that your transmissions are no longer secure. Return to the encrypted mode as soon as possible, and
do not discuss any critical or confidential information while in the non-encrypted mode of operation.
To activate “Follow-Me” scanning, first select the
channel you want to designate as the “User-Assigned Priority Channel” and switch the
TOGGLE switch to the assigned position. Then
turn the CH selector knob to the “Scanning Start”
channel which has been programmed by your
dealer to activate the scanner. When the scanner
stops on an “Active” channel, the User-assigned
Priority Channel will automatically be checked
every few seconds; if activity is found on the Userassigned Priority Channel, the radio will switch
between it and the Dealer-Assigned Priority
Channel, if any.
Lock
Switch the TOGGLE switch to lock the top-panel
keys; this can be enabled to prevent radio settings
from being disturbed.
Follow-Me DW
To set up a “Dual Watch” frequency pair using the
“Follow-Me” feature, select a channel using the CH
selector knob. Now press the assigned Soft key;
pressing the assigned Soft key locks the current
channel as the User-assigned Priority Channel. Now
rotate the CH selector knob to another channel (not
the “Scanning Start” channel). Your radio will now
switch back-and-forth between the currently-selected channel (shown on the CH selector knob)
and the User-assigned Priority Channel.
During “Follow-Me” scanning (after you have
Follow-Me Scan
“Follow-Me” Scan feature checks a User-assigned
Priority Channel regularly as you scan the other
channels. Thus, if only Channels 1, 3, and 5 (of
the 8 available channels) are designated for “Scanning,” the user may nonetheless assign Channel
2 as the “User-assigned” Priority Channel via the
“Follow-Me” feature.
12
VX-900U OPERATING MANUAL
ADVANCED OPERATION
pressed the key), you can set up the “Dual Watch”
feature by rotating the CH selector knob to another channel. The radio will then scan back and
forth between the original User-assigned Priority
Channel and the newly-selected channel.
The Priority Channel you have assigned (before
pressing the key) will be retained in memory until you change it.
Channel Group Selection
The VX-900 is capable of separating its 512
memory channels into any of 20 Groups. There
is no limit as to the number of channels which
may be assigned to each Group. The Dealer will
have made the Group assignment at the time of
channel programming. At the same time, one of
the Soft keys will be assigned as the Channel
Group Selection key.
To change Channel Groups, press the assigned Soft key to step through the available
Groups. Once the desired Group is reached, rotate the CH selector knob to select the desired
channel within the selected Group.
You may wish to have the Scanner (described
previously) pass through more than one Group
during the scanning process (normally, scanning
VX-900U OPERATING MANUAL
is performed within the current group only). To
include the current Group in the scanning loop,
press and hold in the assigned Soft key for one
second.
To remove a Group from Group Scan, press
and hold in the assigned Soft key again for one
second.
Multi-Group Scanning is only possible if you are
using the “User Scan” list.
The VX-900 has two scanning “lists:” the “Dealer
Scan” list and the “User Scan” list. The “Dealer
Scan” list is a fixed group of stations which will
be included when scanning is activated. The “User
Scan” list is a different list, initially arranged by
the Dealer, which may be modified by the User
(if, for example, you want to delete one or more
of these channels from the scanning list).
To edit the User Scan list, press and hold the
soft key (assigned to the Group Up/Down function) to delete the current Memory Group from
the Scanning. Alternatively, press and hold the
“Scan” Soft key for one second to delete the
Current Memory channel from the Scanning.
When you delete a Group or channel, “-SKIP-”
will appear on the LCD for one second after press-
13
ADVANCED OPERATION
ing the Soft key. To restore a particular channel
to your scanning list, press and hold in the Soft
key again for one second; “- STOP -” will appear
on the LCD for one second after pressing the Soft
key.
Call/Reset
This feature, if enabled, allows the user to change
the 3-digit Page Call code, used to call other similarly-equipped stations. Press the Dealer-assigned
Soft key, followed by the three digits representing the Page Call code of the station you wish to
call. Three tones will be heard after the last key is
pressed (the new code will now be transmitted).
The receiver squelch of the other station will be
opened, and you can begin communication.
14
Speed Dial
Your Dealer may have pre-programmed Auto-Dial
telephone number memories into your radio.
To dial a number, press the Dealer-assigned Soft
key for Speed Dialing, then press the numbered
key corresponding to the Auto-Dial memory number list provided by your Dealer. The DTMF tones
sent during the dialing sequence will be heard in
the speaker.
Emergency
The VX-900 includes an “Emergency” feature
which may be useful if you have someone monitoring on the same frequency as your transceiver’s
channel. For further details contact your VERTEX STANDARD dealer.
VX-900U OPERATING MANUAL
ADVANCED OPERATION
ARTS (Auto Range Transpond System)
DTMF Paging System
This system is designed to inform you when you and
another ARTS-equipped station are within communication range.
This system allows paging and selective calling, using DTMF tone sequences.
During ARTS operation, your radio automatically
transmits for about 1 second every 25 seconds (the
interval is programmed by the Dealer) in an attempt
to shake hands with the other station.
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.
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.
VX-900U OPERATING MANUAL

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.
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.
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.
