Q: No response after powering on
A: This may indicate a depleted battery. Connect the charger to the main unit and attempt to power it on again. If it functions normally, the main unit battery requires charging. You may choose to operate while connected to the charger, or use it after a full charge.
Q: Buzzer sounds after powering on
A:The main unit battery power is insufficient. Connect an external power source or charge the unit before use.
Q: Main unit menu functions normally, but external signals show no response
A:The main unit battery has insufficient power or poor contact. If the buzzer sounds when the main unit backlight is activated, this indicates low battery power; connect to an external power source or charge before use. Otherwise, check for reliable contact.
Q: Battery operating time is too short
A:The battery is faulty and requires reactivation.
Q: Freezes during testing
A:External signal interference is excessive. This is typically caused by the earth probe accidentally touching a live wire. Switch off and restart.
