Vertex Standard VX-4500 Series User manual

Transceiver insTallaTion Guide
This manual is intended for use by experience technicians familiar with
similar types of equipment. Specically, it contents installation information
required for the VX-4500/-4600 transceiver.
For information related to the service of the VX-4500/-4600 transceiver, re-
fer to the applicable manuals available separately.
When installing the VX-4500/-4600 transceiver, make sure to
plan the installation carefully and leave additional room in the
rear of the radio for cabling and accessory connections; in the
front of the radio for access, controls, and cabling; and to the
sides of the radio so that you may access and install the knob
screws or hex head bolts.

Mounting Bracket installation
The supplied mounting bracket allows desktop or overhead mounting.
 Use a 7/32 inch (5.5 mm) bit to drill the holes to a surface which is more 0.4
inch (10 mm) thick and can support more than 3.3 lbs (1.5 kg) and secure the
bracket with the supplied screws, spring washers, at washers, and nuts.
You may secure the bracket using the supplied tapping screws, instead of the
screws and nuts. In this case, drill the small pilot holes instead of the 7/32 inch
(5.5 mm) holes.
 Install the transceiver to the bracket using the supplied Knob Screws and
Washers (or Hex Head Bolts, depending on the situation).
Use only the supplied Knob Screws with Washers, Hex Head Bolts,
or equivalent size screws (HSM5X12).

MoBile installation
Power Connection
VX-4500/-4600 transceiver operates only in negative ground electrical systems.
Before starting the installation, make sure that the ground polarity of the vehicle
is correct. Accidentally reversing the polarity will not damage the transceiver, but
will cause the cable fuses to blow.
To minimize voltage drop and avoid blowing the vehicle’s fuses, connect the sup-
plied DC power cable directly to the battery terminals. Do not attempt to defeat or
bypass the DC cable’s fuse - it is there to protect you, your transceiver, and your
vehicle’s electrical system.
Warning! Never apply AC power to the power cable of the transceiver,
nor DC voltage greater than 15.8 Volts. When replacing the fuse, only use
a 10-A fuse (for 25 W model) or 15-A fuse (for 45 W/50 W models). Failure to ob-
serve these safety precautions will void the Limited Warranty on this product.
 Before connecting the transceiver, check the voltage at the battery terminals
while revving the engine. If the voltage exceeds 15 Volts, adjust the vehicle’s
voltage regulator before proceeding with installation.
 Connect the RED power cable lead to the POSITIVE (+) battery terminal,
and the BLACK power cable lead to the NEGATIVE (–) terminal. If you
need to extend the power cable, use #12 AWG or larger insulated, stranded
copper wire. Solder the splice connections carefully, and wrap the connections

thoroughly with insulating electrical tape.

Wire the cable so that not to disturb with the driving.
 Before connecting the cable to the transceiver, verify the voltage and polarity
of the voltage at the transceiver end of the DC cable using a DC voltmeter.
Now connect the transceiver to the DC cable.
Antenna Installation
The mobile antenna installation is limited to metal body motor vehicles or vehicles
with appropriate ground planes.
Antennas mounted on the trunk should be located at least the following distance
away from operator and passengers in order to comply with the FCC/IC RF expo-
sure requirements. If can not meet these requirements, the antenna must be placed
in the center of the roof.

Base station installation
Power Connection
Operation of the VX-4500/-4600 transceiver from an AC line requires a power
supply capable of providing at least 10 Amps (for 25 W model) or 15 Amps (for
45 W/50 W models) continuously at 13.6 Volts DC. Please contact your dealer to
select an optimal power supply that satisfy these requirements.
Use the supplied DC power cable for making power connections to the power
supply. Connect the RED power cable lead to the POSITIVE (+) power supply
terminal, and connect the BLACK power cable lead to the NEGATIVE (–) power
supply terminal.
Antenna Installation
When used the VX-4500/-4600 transceiver as a base station, the antenna installa-
tion must comply with the following requirements in order to ensure optimal per-
formance and compliance with the RF energy exposure limits in the standards and
guidelines.
 The antenna should be mounted outside the building on the roof or a tower if
at all possible.
 As with all xed site antenna installations, it is the responsibility of the licens-
ee to manage the site in accordance with applicable regulatory requirements
and may require additional compliance actions such as site survey measure-
ments, signage, and site access restrictions in order to insure that exposure
limits are not exceeded.
