FIRECORE FD30 Laser Detector

Quick Setup & Use
- Put the laser level into pulse mode (outdoor).
- Turn on the FD30 receiver.
- When the receiver correctly detects the laser line, the laser indicator shows green and the receiver beeps.
- Interpret alignment signals: if the datum is below the laser line, move up; if the datum is above the laser line, move down; if the datum is in line, the LED indicator is green.
- If you want to turn off the beep, long-press the power button.
- Ensure the laser level and the FD30 sensing window are clean and recheck batteries in both devices (laser level & FD30 receiver).
- Do not expose the machine to explosive environments such as flammable and explosive gases, liquids, and dust. The instrument may produce sparks that ignite dust or smoke.
- When you do not use the instrument, please put it in places where children and untrained personnel cannot touch. It is dangerous for untrained personnel to operate the laser.
- When you do not use the laser instrument, switch it to the OFF position. Keeping the laser always-on will increase the risk of the laser beam and shorten the life of the instrument.
- Do not disassemble or modify the instrument at any time, otherwise, exposure to dangerous laser beams may be incurred.
- When using the instrument, do not energetically fall and smash it, otherwise, the instrument’s accuracy and operational timeliness may be affected by large vibrations.
- Put the laser detector safely onto a flat surface; if it falls from a high place, it may be damaged.
Battery Safety Warning:

Operating Instructions
How to use FD30 receiver with a laser level?
Turn on the pulse mode of the laser level, and then turn on the FD30 receiver. When the receiver detects the laser line correctly, the laser indicator will show green and beep. The beep can be turned off by long pressing the power button.
Buzzer Reminders
- A continuous beep tone signals that the laser beam has been detected
- Intermittent beep tones signal – Move Up / Move Down
Precise Optical Signals

Troubleshooting
- No detection / no green indicator: Ensure the laser level is operating in pulse mode and that the receiver window is clean.
- Misalignment guidance (beeps or LED not indicating correctly): Use the correct “move up / move down” interpretation based on whether the datum is below or above the laser line.
- Beep behaviour: A continuous beep means the laser beam has been detected. Intermittent beeps indicate move up / move down. To disable the beep, long-press the power button.
- Receiver cannot sense from the back: Make sure the laser line is sensed from the front; it cannot be sensed from the back.
- Battery-related issues: If the device is not used within 7 months, remove the battery. Also recheck the batteries in both the laser level and the FD30 receiver.
