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.
