Installation

Transceiver Mounting

Plan the location of the transceiver and microphone bracket before starting the
installation. 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 is a very important factor affecting transmission and reception. It is for this
reason that we strongly recommend that you install only a quality antenna in your new
HR 2600 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
5052 transmission line to the radiating element. Your Uniden dealer is qualified to assist
you in the selection of the proper antenna to meet your application requirements.
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.
A short base loaded whip antenna is more convenient to install, but the efficiency is less
than a quarter wave whip.
For marine installations, consult your dealer for information regarding an adequate
grounding system and prevention of electrolysis
Warning: Standing Wave Ratios in excess of 2:1 may cause transmitter
damage.

Ground Information

Most newer U.S. and foreign made cars and small trucks use a 13.8 V DC nominal
negative ground system, while some older cars and large trucks use a positive ground
system. A negative ground system is generally identified by the negative (-) battery
terminal being connected to the vehicle frame or engine block, but if you cannot
determine the polarity of your vehicle or are unsure, contact your vehicle dealer for
definite information.
Warning: Your HR 2600 is designed for operation on a 13.8 V DC nominal, negative
ground system only. Operation on other voltages or polarities may cause fires,
transceiver damage, and/or other hazards.

Power Cord Connection

The red lead (with the inline fuse) of the supplied power cord is to be connected to a
"hot" (positive) wire, and the black lead to ground. As the HR 2600 draws appreciable
current during transmitting, you may wish to connect the positive lead directly to the
battery, or to a main supply wire.

Operation

Selecting a frequency
VFO Operation
Selecting an operating frequency using the HR 2600's built-in VFO is easy. Make sure
that the F. Lock key is NOT depressed, and then simply rotate the dial, or use the A and
V buttons on the microphone or front panel until the desired operating frequency is
displayed. The VFO will step in either 10 KHz, 1 KHz, or 100 Hz increments. The step
increment is indicated by a line under one of the 3 rightmost digits of the frequency
display. To change the VFO step, press the Span button until the desired step is
indicated by the black line. When using the VFO, you do not need to manually select the
band segment, as this is done automatically, so that tuning is continuous throughout the
entire operating frequency range.
Repeater Operation
For working FM repeaters, press the RPT button on the front panel. A "P" will be
displayed over the band segment display. When in this mode, the transmit frequency is
100 KHz lower than the receive frequency.
USB/LSB/AM/FM Operation
Using the HR 2600 for voice communications as either USB, LSB, AM or FM modes is
simple. Simply select your desired operating frequency, turn the mode switch to the
desired type of operation, and the PTT switch controls the transmit and receive. To fine
tune the receive signal in USB or LSB, you can use either the VFO or RIT controls.
(Note: Using the RIT control to fine tune the receive frequency will NOT affect the
frequency display.)
The Mic Gain control can (and should) be used when you are transmitting from a high
ambient noise environment. Pressing the Mic Gain control reduces the gain of the
transmit audio amplifier. Press the Mic Gain control again to restore it to normal
operating condition
Noise Blanker
The noise blanker has been designed specifically to remove the interference generated
by vehicle ignition systems. To use the noise blanker, simply press the NB switch. To
disable the noise blanker, just press the NB switch again
F. Lock
The Frequency Lock function is used to lock the frequency determining controls against
accidental changes. To lock the frequency controls, press the F. Lock button. To unlock
the frequency controls, press F. Lock again
