1- Backlight / On-Off
Switches the TUNER on and off (press for at least 2 seconds to turn off the TUNER) and
toggles backlight on and off when the TUNER is on (backlighting is available only when
the TUNER is powered by the external 9 VDC power supply). Backlight status is
memorized by the TUNER.
If no detector head is connected when the TUNER is powered on, the message “No
Detector” will be displayed. Turn off the TUNER; connect the detector to the Probe
Input Jack (see section 1.4) and turn the TUNER on again.
If the detector is not recognized by the TUNER , the message “Bad Detector” will be
displayed. Make sure you use a detector head that is compatible with the TUNER (see
section 1.2 for the list of compatible detector heads).
2- Speed / Zero
Press and release this key to toggle between fast and slow modes. The fast mode
enables anticipation, which shortens the natural response time of the detector. The slow
mode disables anticipation. By default, the TUNER will always power-up in fast mode.
