When the batteries are discharged enough to compromise the measurement, the TUNER displays “LO
BATT ” instead of the measurement. Refer to section 3 to replace the batteries.
If the voltage supplied by the external power supply is lower than 7 Volts, the TUNER displays “LO
JACK”.
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).
