1. Mode Switch -Thiscontrol is used to select the desired transmit mode. The
modes available are: CW, LSB,USB,AM, and FM.
2. SWRjCAL Control -Thiscontrol is used to adjust the calibration of the SWR
meter while in SWRCALmode.
3. RITControl- The Receiver Incremental Tuning control isused to fine tune the
received signal. This isused in USBand LSBmodes to obtain maximum clarityof
reception, and in CWmode to control the pitch ofthe beat note. The R/Tcon-
trol can tune the receive frequency about :t 3 KHz. This control will not aff~ct
the transmit frequency, or the frequency display, but will change the receive
frequency.
4. RFGain Control- Thisisused to vary the RFinput to the receiver. Thiscontrol
is used to help eliminate strong, adjacent signals.
5. Mic Gain Switch -Pressing this switch activates the built-in microphone at-
tenuator. This feature isdesigned to be used when operating the HR2510 in
high ambient noise environments.
6. TX Switch -The TXswitch is used to lock the transmitter on for tuning pur-
poses, except in CW mode. In CW mode the external key must be locked
down. The rT)icrophone is disconnected unless the PTT switch is also de-
pressed.
7. Meter Switch -Thisswitch isused to select the operating mode"forthe multi-
funcion meter. The meter modes are: S/RF, Modulation, SWRCalibration sett-
ing, and SWR.Each time the Meter switch ispushed, the next mode isselected.
See the operation section formore information on meter usage. The currently
selected mode is displayed above the meter.
8. PA Switch -Pressing this switch enables the PA Mode, ifan external PAspeak-
er isinstalled. When in PAmode, the normal transmit functions ofthe radioare
disabled, but the receive audio is routed through the PAspeaker.
9. NB Switch -Pressing this switch enables the built in noise blanker. The noise
blanker in your HR2510 isvery effective in eliminating interference generated
by vehicle ignition systems.

10. Dim Switch -Pressing the Dimswitch dims the display backlighting. Press
again to return- backlighting to its normal (high) level.
11. Scan Switch -The Scan control is used to scan up to 50 channels in each
band segment. See the section on operation for more information on using
the Scan Control.
12. Span Switch -This control is used to select either 10KHz, 1 KHz, or 100 Hz
steps forthe VFO. The currently selected step isindicated bya line under the
relevant digit on the Frequency Display.
13. Channel /\ and V - Pressing these controls will step up or down to
the next 10KHzchannel in the currently selected band segment. The current-
lyselected channel is displayed next to the frequency display.
14. Band Switch -Pressing this control will select one of the four band seg-
ments. Band segments are: a:28.0000 - 28.4999, b:28.5000-28.9999,
c:29.0000-29.4999, and d:29.5000-29.6999 MHz. The currently sel,ected
band segment is displayed above the channel display.
15. F. Lock Switch - Pressing the Frequency Lockbutton willdisable allfrequen-
cydetermining controls on the front panel, to prevent accidental changes of
frequency.
16. VFO Control -The Variable Frequency Oscillator-control is used to select
the desired transmit and receive frequency. Tuning iscontinous throughout
the entire range of the HR 2510, with no need to select band segments.
17. Squelch Control -The Squelch control is used to adjust the squelch func-
tion, which eliminates the "rushing" sound between transmissions. Turning
the squelch control CCW until it clicksenables the auto squelch, eliminating
the need to manually adjust the squelch.
18. On/Off/Volume Control -This control is used to turn the unit on or off
and to adjust the volume.
19. Beep Switch -Pressing this control willcause a short beep tone to be trans-
mitted whenever you release the PTTswitch on the microphone.

'Installation.
Transceiver Mounting
Plan the location ofthe transceiver and microphone bracket before starting the in-
stallation. Select a location that isconvenient for operation and does not interfere
with the driver or passenger inthe 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
inyour new HR2510 system. Youhave purchased a superior quality transceiver;
don't diminish its performance by installing an inferior antenna.
Only aproperly 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 isto 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 WaveRatios 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 apositive ground
system. A negative ground system isgenerally 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 VDC nomina/, negative
ground system only. Operationon 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)ofthe 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.
