OPERATION DETAILS
Battery Information
The SILVER BULLET RX7500 operates on two AA alkaline batteries. To ensure optimum performance
and battery life, we advise against using other types of batteries. Using AA rechargeable batteries
is NOT recommended as the resulting battery life will be shorter due to characteristics of
rechargeable batteries
Battery Installation
1. BE SURE the radar detector is turned off; disconnect the battery box from the radar detector.
2. Remove the battery door on the battery box.
3. If replacing batteries, remove old batteries by pulling the battery removal ribbon.
Do not mix old and new batteries for maximum battery life.
4. Insert two fresh AA alkaline batteries into the battery box, observing the polarity indication
inside the battery box.
5. Replace the battery box door and reconnect the battery box to the radar detector.
6. The radar detector is ready for use.

Battery Life
The SILVER BULLET RX7500 can provide approximately 30-40 hours of battery life from two AA alkaline
batteries. Battery life is affected by many variables, such as the brand and condition of the batteries, the
ambient temperature, the number and strength of engaged signals, and the duration of reported alerts,
backlight, and user settings. The estimated battery life provided here is based on battery aging tests
conducted in laboratory environments.
Low Battery Indicator
A “LOW BATTERY” message will appear when 2 to 4 hours of battery life remain. This message will scroll
across the screen for 10 seconds accompanied by a beeping sound. This will repeat every 30 minutes until
no battery power remains and the radar detector shuts off.
We suggest keeping the power cord readily available. If your batteries are drained, the cord
will allow you to continue using your radar detector until you can replace the batteries.
Auto Power-Off
To conserve battery power, the SILVER BULLET RX7500 will automatically shut off when no signal detection
and no button manipulation have occurred for 40 minutes. The radar detector will display ”ENTERING
SLEEP MODE… PRESS ANY BUTTON TO STAY ON” and will beep for 20 seconds before powering down. To
keep the radar detector on, just press any button while the audio and visual warnings are displayed.
The automatic power-off does not function when the radar detector is operated by power cord.
Please turn off the radar detector whenever you leave your vehicle. Even a weak signal can
cause it to remain on and drain your batteries.
If the radar detector was turned off automatically, you can turn it back on by pressing any
button, or by moving the power switch to OFF and then to ON.

OPERATION DETAILS
Turning On the Radar Detector
•Move the POWER switch to ON.
•The screen will display ”SENSORO RADAR DETECTOR * * * FILTER-NORMAL” if itʼs your rst use
since purchase.
•If you selected an alternate alert lter mode during previous use, it will display either “FILTER-
HIGH” or “FILTER-OFF” instead of “FILTER-NORMAL” in the message above per your selection.
•The screen will then display “SYSTEM ON”.
Using the Backlight
Press the BACKLIGHT button to switch the backlight on or off. The radar detector will sound 1 beep
when the backlight is turned on, and 2 beeps when it is turned off.
If the backlight stays on for more than 15 minutes, the screen will scroll twice ”BACKLIGHT IS
ON… TURNING OFF WILL PROLONG YOUR BATTERY LIFE”. This will repeat every 15 minutes.
The backlight is automatically on for 5 to 20 seconds at the following events:
•While the tutorial messages are displayed – 15 seconds
•While the auto power-off messages are displayed – 20 seconds
•While the low battery message is displayed – 10 seconds
•When a button is pressed – 5 seconds
•When an alert message is displayed – 5 seconds

17
Using the Mute Feature
Press the MUTE button to switch between “START MUTE” and “END MUTE”. In the “END MUTE” mode,
the radar detector automatically lowers the audio alert level to the ambient noise level in your vehicle
when it detects a continuous signal for 5 seconds or more. Also the audio alert level remains low
for 60 seconds, even if, during that time, a second separate signal is detected. In the “START MUTE”
mode, the radar detector will remain completely silent but will continue to provide visual alerts.
Understanding Signal Alerts
Three (3) radar bands (X, K, and superwide KA) and one (1) laser band are typically used by police
radar/laser devices. When a radar signal is detected, the screen displays the name of the radar band
– “X”, “K”, or “KA” – together with a number indicating the strength of the detected signal (called
the signal strength meter). When a laser signal is detected, the screen displays “LASER”.
• There are 8 levels in the signal strength meter – 1 to 8. The higher the number, the
stronger the signal.
• The signal strength meter can provide a good indication of the proximity of the detected
signal. Usually, strong signals are closer to you than weak signals.
• When “LASER” alert is displayed, it is highly recommended that you promptly reduce your
speed if youʼre driving faster than the speed limit. Police laser devices can measure the
speed of a target vehicle when it is within 1,500 feet in line of sight.
Except for a few early devices, X band (10.50~10.55 GHz) was the only frequency used for
police radar until the mid-1970ʼs. In 1976 radar devices using K band (24.05~24.25 GHz)
were introduced; this led to the development of the rst dual band (X and K) radar detectors.
OPERATION DETAILS

16
17
OPERATION DETAILS
A proliferation of radar devices using KA band frequencies began in 1987 with the
introduction of photo radar (34.3 GHz) and was followed by the Stalker (34.2~35.2
GHz) in 1991 and the BEE 36A (33.4~34.4 GHz) in 1992.
Early detectors needed only to listen for X band radar. When K band arrived, dual band
detectors able to receive both frequencies (X and K) were required. The introduction of KA
band photo radar (34.3 GHz) led to the development of tri-band detectors able to detect X, K,
and a small portion of KA band. A fourth category of radar receivers called “wide-band” with
X, K, and wide KA (34.2~35.2 GHz) band detection capabilities reached the market following
the introduction of Stalker radar. Finally, in response to the BEE 36A, a new generation of
“superwide-band” radar detectors was developed. They detect all radar devices operating
on X, K, and superwide KA (33.4~36.0 GHz) band. All SENSORO radar/laser detectors are
superwide band receivers.
Laser devices transmit an invisible light beam at a frequency (more accurately a
“wavelength”) of 904 nanometers. A nanometer is how a light wavelength is measured.
Different laser devices operate at different light pulse rates and some manufacturers call them
“bands”. All SENSORO radar/laser detectors can detect all current laser devices in use.
Less than 1,000 laser devices are in service in 45 states at present. Most are used by city police
on urban multi-lane roadways. The use of laser devices for speed monitoring is expected to
increase, but will remain limited due to their high cost and limited attractiveness to agencies
that favor the convenience, offered by conventional moving radar. Currently, laser guns
account for less than 5% of the total number of speed monitoring devices (radar and laser)
sold in the U.S. annually; during the next ve years, this gure is expected to remain under
8%. Laser devices will likely be in service in every state within a few years.

OPERATION DETAILS
Using the Alert Filter Button
Press the ALERT FILTER button to switch between lter modes. The factory default is FILTER-NORMAL.
•FILTER-NORMAL – Optimized ltering for typical city or highway driving. The NORMAL mode
lters out all X band and other known radar signals commonly associated with annoying false
alerts in city and suburban areas. When this mode is selected, the screen will scroll “FILTER-
NORMAL MODE”.
•FILTER-HIGH – Increased ltering to reduce most false alerts, good for high-density commercial
areas. The HIGH mode is ideal when youʼre receiving frequent false alerts. Most North
American speed monitoring systems use the K or KA bands, and this mode will not adversely
affect the sensitivity to police radar/laser devices. When this mode is selected, the screen will
scroll “FILTER-HIGH MODE”.
•FILTER-OFF – No ltering of alert signals, ideal for open space areas. The OFF mode eliminates
the X band lter and is recommended for driving in areas where X band radar devices are still
in use. While now being phased out in most areas, X band is still used in some locations. When
this mode is selected, the screen will scroll “FILTER-OFF MODE”.
X band, occupied by police radar, is also used for other devices, such as automatic door
openers like those at supermarkets, burglar alarms, terrestrial microwave emission, and
more. In addition, other radar detectors in close proximity may falsely alert your detector.
Filtering false alerts will help you travel more comfortably.
Invisibility to VG-2 Devices
VG-2 is a technology used by speed monitoring systems to identify vehicles equipped with radar detectors
in instances and locations where they are not legal (such as in vehicles over 10,000 lbs. or in Virginia
and Washington D.C.). The VG-2 interceptors work by detecting emission frequencies (11.4~11.7 GHz)
