'Installation.

Transceiver Mounting

Plan the location of the transceiver and microphone bracket before starting the in-

stallation. Select a location that is convenient for operation and does not interfere

with the driver or passenger in the vehicle. The radio should be secured to a solid

surface, using the mounting bracket and self-tapping screws supplied.

Mobile Antenna

The antenna isa very important factor affecting transmission and reception. It is

for this reason that we ~trQnglyrecommend that you install only a quality antenna

in your new HR 2510 system. You have purchased a superior quality transceiver;

don't diminish its performance by installing an inferior antenna.

Only a properly matched antenna system will allow maximum power transfer from

the 50Q transmission line to the radiating element. YourUniden dealer isqualified

to assist you in the selection of the proper antenna to meet your application re-

quirements.

For automobile installations, a quarter wave whip antenna may be used with

good effect. The most efficient and practical installation is to mount it on the rear

deck or fender top midway between the rear window and bumper.

Ashort base loaded whip antenna ismore convenient to install, but the efficiency

is less than a quarter wave whip.

For marine installations, consult your dealer for information regarding an adequ-

ate grounding system and prevention of electrolysis.

Warning: Standing Wave Ratios in excess of 2: 1may cause transmitter damage.

Ground Information

Most newer and foreign made cars and small trucks use a 13.8 V DC nominal ne-

gative ground system, while some older cars and large trucks use a positive ground

system. A negative ground system is generally identified by the negative (-) bat-

teryterminal being connected to the vehicle frame or engine block, but ifyou can-

not determine the polarity ofyour vehicle or are unsure, contact your vehicle deal-

er for definite information.

Warning: Your HR 2510 is designed for operation on a 13.8 V DC nomina/, negative

ground system only. Operation on other vo/tages orpo/arities may cause fires, tran-

sceiver damage, and/or other hazards.

Power Cord Connection

The red lead (with the inline fuse) of the supplied power cord isto be connected to

a "hot" (positive) wire, and the black lead to ground. As the HR2510 draws ap-

preciable current during transmitting, you may wish to connect the positive lead

direcly to the battery, or to a main supply wire.
