INTRODUCTION
The VX-450 Series are full-featured hand-held FM transceivers designed for business communications in the VHF or UHF Land Mobile bands. These transceivers are designed for reliable business communications in a wide variety of applications with a wide range of operating capability provided by their leading-edge design.
The VX-451 allows to 32-channel capacity and 2 groups. The VX-454/-459 allows to 512-channel capacity and 32 groups which can each be programmed with an 8-character Alpha-Numeric Tag.
Important channel frequency data is stored in EEPROM and flash memory on the CPU, and is easily programmable by Vertex Standard dealers using a personal computer and the Vertex Standard Programming Cable and CE115 Software.
The pages which follow will detail the many advanced features provided in the VX-450 Series transceiver. After reading this manual, you may wish to consult with your Network Administrator regarding precise details of the configuration of this equipment for use in your application.
IMPORTANT NOTICE FOR NORTH AMERICAN USERS REGARDING 406 MHZ GUARD BAND
The U.S. Coast Guard and National Oceanographic and Atmospheric Administration 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 frequency range 406.0 - 406.1 MHz if the apparatus is to be used in or near North America.
Warning - Frequency band 406 - 406.1 MHz is reserved for use ONLY as a distress beacon by the US Coast Guard and NOAA. Under no circumstance should this frequency band be part of the preprogrammed operating frequencies of this radio.

WARNING! FCC RF EXPOSURE REQUIREMENTS
This Radio has been tested and complies with the Federal Communications Commission (FCC) RF exposure limits for Occupational Use/Controlled exposure environment. In addition, it complies with the following Standards and Guidelines:
FCC 96-326, Guidelines for Evaluating the Environmental Effects of Radio-Frequency Radiation.
FCC OET Bulletin 65 Edition 97-01 (2001) Supplement C, Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields.
ANSI/IEEE C95.1-1992, IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.
ANSI/IEEE C95.3-1992, IEEE Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields - RF and Microwave.
WARNING:
This radio generates RF electromagnetic energy during transmit mode. This radio is designed for and classified as Occupational Use Only, meaning it must be used only during the course of employment by individuals aware of the hazards, and the ways to minimize such hazards. This radio is not intended for use by the General Population in an uncontrolled environment.
CAUTION:
To ensure that your expose to RF electromagnetic energy is within the FCC allowable limits for occupational use, always adhere to the following guidelines:
This radio is NOT approved for use by the general population in an uncontrolled exposure environment. This radio is restricted to occupational use, work related operations only where the radio operator must have the knowledge to control his or her RF exposure conditions.
When transmitting, hold the radio in a vertical position with its microphone 2 inches (5 cm) away from your mouth and keep the antenna at least 2 inches (5 cm) away from your head and body.

VX-450 SERIES OPERATING MANUAL
WARNING! FCC RF EXPOSURE REQUIREMENTS
The radio must be used with a maximum operating duty cycle not exceeding 50%, in typical Push-to- Talk configurations.
DO NOT transmit for more than 50% of total radio use time (50% duty cycle). Transmitting more than 50% of the time can cause FCC RF exposure compliance requirements to be exceeded.
The radio is transmitting when the red LED on the top of the radio is illuminated. You can cause the radio to transmit by pressing the P-T-T button.
SAR compliance for body-worn use was only demonstrated for the specific belt-clip (CLIP-20). Other body-worn accessories or configurations may NOT comply with the FCC RF exposure requirements and should be avoided.
DO NOT transmit when the radio is used in Body Worn configuration with the following accessory: belt-clip.
It must be used ONLY for (1) there is 4 cm distance from the body during transmitting, (2) monitoring purposes, using the speaker only and (3) for carrying purposes.
Always use Vertex Standard authorized accessories.
The information listed above provides the user with the information needed to make him or her aware of RF exposure, and what to do to assure that this radio operates with the FCC RF exposure limits of this radio.
Electromagnetic Interference/Compatibility
During transmissions, this radio generates RF energy that can possibly cause interference with other devices or systems. To avoid such interference, turn off the radio in areas where signs are posted to do so. Do not operate the transmitter in areas that are sensitive to electromagnetic radiation such as hospitals, health care facilities, aircraft, and blasting sites.

Battery Pack Installation and Removal
To install the battery pack, align the battery pack to the radio with an offset about 1/2 inch from the top edge of battery compartment, then slide the battery pack upward until it locks in place with a “Click.”
To remove the battery, turn the radio off and remove any protective cases. Slide the Battery Pack Latch on the bottom of the radio toward the front panel while sliding the battery down about 1/2 inch. Then lift the battery out from the radio.
Do not attempt to open any of the rechargeable Lithium-Ion packs, as they could ex-
plode if accidentally short-circuited.
Low Battery Indication
As the battery discharges during use, the voltage gradually becomes lower. When the battery voltage becomes to low, substitute a freshly charged battery and recharge the depleted pack. The LED indicator on the top of the radio will blink red when the battery voltage is low.
Caution 
Danger of explosion if battery is replaced with an incorrect battery. Replace only with the same or equivalent type.
Battery Charging
Referring to Figure 1, adjust the direction of the Battery Holder of the CD-49 Desktop Charger in accordance with the battery pack being charged; Push in both sides of the Battery Holder while pulling up on the Battery Holder to remove it from the charger base, select the correct direction of the Battery Holder for the battery being charged, then

AC line outlet. |
|
|
|
Insert the battery pack into the |
Desktop |
|
Charger while aligning the slots of the battery pack with the guides in the nest of the CD-49; refer to the illustration at the right for details on proper positioning of the battery pack. If charging with the transceiver attached, turn the transceiver off. The antenna jack should be at the left side when viewing the charger from the front.
If the battery pack is inserted correctly, the LED indicator will glow red. A fully-discharged battery pack will charge completely in 1.5 - 3.0 hours (depending on the battery pack being charged).
When charging is completed, the LED indicator will change to green.
Disconnect the battery pack from the CD-49 Desktop Charger and unplug the PA-45 AC Adapter from the AC line outlet.
WARNING 
Perform the battery charging where the ambient tempera-ture range +5 °C to +35 °C. Charge out of this range could cause damage to the battery pack.
