INSTALL AND TURN ON R4
You can mount the R4 on the windshield (1- and 2- cup suction brackets included) or
on the dashboard (hook and loop tape included).
INSTALL/POWER ON
Windshield
When you mount the R4 on the windshield, mount it in the middle of the windshield
between the driver and passenger. Be sure there are no obstructions and that there
is a clear view through the windshield.

1. Attach the rubber suction cups to the bracket and push the cups firmly onto the
windshield.
2. Slide the unit onto the bracket until it clicks into place.
3. Plug the power cord RJ11 connector into the R4 and plug the cigarette lighter
adapter into the vehicle’s cigarette lighter.
4. When the vehicle turns on, the R4 automatically turns on and runs through a
self test cycle.
Release the R4 from the bracket by pressing the Eject key on top of the detector.
Dashboard
The same types of mounting requirements for the windshield apply for mounting the
unit on the dashboard.
1. Attach the unit to the dashboard using the hook and loop fastener tape.
Be careful not to cover any air vent holes with the hook and fastener tape.
2. Plug the power cord RJ11 connector into the R4 and plug the cigarette lighter
adapter into the vehicle’s cigarette lighter.
3. When the vehicle turns on, the R4 automatically turns on and runs through a
self test cycle.
Pull the unit from the dashboard, separating the hook and loop tape.
MENU SYSTEM
Menus let you set up the system to your own requirements. You can turn different
bands on and off and set specific items such as speed or auto mute.
Press MENU to access the Menu system. The screen displays the selection’s current
status. For example, if you press MENU and the screen displays Voice: ON, you have
the option of turning Voice to OFF.
Use the following keys to navigate the menus:
•
MENU
: Change a menu item setting (press and hold to exit the Menu system).
•
VOL +
: Go to the next Menu item.
•
VOL –
: Go to the previous Menu item.
The R4 menu system is 2-tiered; Basic and Expert. Basic level menus let you set basic
elements such as red light camera alarms, band announcement (voice), and how you
want the OLED to appear (Alert Display #1 or #2 menu option, for example), among
other options. Expert level menus allow you to fine-tune your detector by activating
the traffic sensor filter, turning threat notifications on and off, or changing the colors
on the OLED screen, among other options.

- 14 -
In addition, GPS can be turned on and off only through the Expert menus. GPS status
also affects which menus may display in the Basic or Expert levels. For example, if
GPS is turned on, then the Speed Camera Alarm menus display. If it is not turned on,
then those menus will not display.
If a menu depends on Level, Mode, GPS , or a different status, that dependency will
be noted in the specific menu entry itself.
The following table lists all the menu options from all levels and modes.
Several menu items only display if GPS is set to ON. These entries are noted in the
following table.

AUTO MUTE/AUTO MUTE VOLUME
When the R4 detects a signal, it sounds an alarm at the current volume level. To
make the alarm quieter, turn Auto Mute on through the menus (see page 22). This
will reduce the volume to the level set (0 - 7) in the Auto Mute Volume menu (see
page 22).
If the current volume level is 0, the R4 will not change the volume to the Auto Mute
Volume level; it will keep the volume level at 0.
Auto Mute ends 10 seconds after the alarm ends unless:
• The same signal is detected within that 10 second period; then, Auto Mute stays
on.
• A different band signal is detected during that 10 second period; then, Auto Mute
turns off and then back on at the current volume level.
Auto Mute does not apply to Laser Alert.
BLOCK BLIND SPOT MONITOR SYSTEMS
Some vehicles come equipped with Blind Spot Monitors (BSM). These systems send
out limited range K signals that alert the driver to other vehicles that come within
that range. Your R4 can pick up those signals from other vehicles and keep alerting

- 30 -
you to them. You can block those signals by turning on K Block Filter in the Expert
level menus.

MODES (HIGHWAY, CITY, AUTO, AND ADVANCED)
Uniden’s R4 radar detector operates in two different frequency (X, K, and Ka band)
sensitivity modes - Highway and City. Highway mode is the most sensitive, with
maximum detection ranges while on the highway or open road. City is on the lower
end of the detection scale for city driving. City mode reduce sensitivity so that false
signals (such as from automatic door openers) are filtered out.
Under factory default conditions (X band = off on all modes, K and Ka bands = on),
the band sensitivities are:
• Highway: X, K, and Ka bands full sensitivity.
• City: X and K bands sensitivity reduced; Ka band full sensitivity.
• Auto: Auto mode will switch the R4 between Highway and City depending on the
Auto City Speed menu setting (see page 15). Sensitivity is the same as Highway
and City settings.
• Advanced: Adjust the sensitivity level for each band.
1. Press MENU. The current level and mode display.

MEMORY QUOTA
Memory Quota refers to the number of user and mute memory points saved on the
R4. The R4 can save up to 2,000 points between the two. The maximum amount
saved for one point type is 1,750; the minimum amount saved for the other point
type would be 250 (total = 2,000 points). If the first point type drops by 250 points
(1,500 points), the other type can increase by 250 points to 500 points (total =
2,000).
The Memory Quota menu (Expert level, GPS On; page 24) sets these numbers in
50 point increments.
1. Select Memory Quota from
any Expert level menu. The

THREATS
The R4 detects up to 4 radar band signals (threats) at a single time. The strongest
rader signal is designated as the Priority signal, and its frequency displays on the
OLED. The other 3 signals (threats) are indicated in the left side of the display. In the
following example, 3 K bands and 1 X bandfrequencies are detected.
K
K 24.158 GHz
KX
The Priority menu setting determines which type of frequency displays on the OLED
(see page 18). If Priority is set to Signal priority, the strongest signal displays on the
OLED. If Priority is set to Ka Priority, the Ka band radar signal displays on the OLED.
USER MARKS (MEMORY POINTS)
With the R4, you can mark geographical points where you commonly encounter
radar transmissions, These can be school zones, red-light cameras, and places where
police frequently monitor traffic.
When you are at the location, press MARK. The R4 announces “User mark logged.”
Now, when you approach these points, the R4 announces “User mark ahead.”
Press and hold MARK at that location to delete that user mark.
The R4 registers up to 2,000 marks split between mute memory marks and user
marks. These marks are split at 1750 maximum and 250 minimum between the two
mark types.
USER-SET AUTO CITY SPEED
When you set speed parameters through the Auto City Speed menu in both Basic
and Expert modes, the R4 will change from Highway to City (or from City to Highway)
mode when the vehicle reaches that set speed. For example, if Auto City Speed is
set to 60 mph (90 km/h), driving over that limit will switch the R4 to Highway mode;
driving below it will switch the R4 to City mode.
MAINTENANCE
MAINTAINING THE EQUIPMENT
The R4 requires very little physical maintenance. Wipe it with a soft cloth to keep
dust from accumulating. Check the power cord connections to keep them clean and
