Starting operation
- Protect the laser receiver against moisture and direct sunlight.
- Do not subject the laser receiver to extreme temperatures or variations in temperature. As an example, do not leave it in vehicles for longer periods. In case of large variations in temperature, allow the laser receiver to adjust to the ambient temperature before putting it into operation. In case of extreme temperatures or variations in temperature, the accuracy of the laser receiver can be impaired.
- Keep the work area free from obstacles that could reflect or obstruct the laser beam. For example, cover any reflective or shiny surfaces. Do not measure through panes of glass or similar materials. The measurements may be distorted by a reflected or obstructed laser beam.
Position the laser receiver so that the laser beam can reach the reception area (1). Align it so that the laser beam runs straight through the reception area (as shown in the figure).
For rotary lasers with multiple operating modes, select the horizontal or vertical operation with the highest rotational speed.
- A loud audio signal sounds when switching on the laser receiver. Therefore, keep the laser receiver away from your ear or other persons when switching it on. The loud sound can damage hearing.
To switch on the laser receiver, press the on/off button (19). All display indicators and all LEDs light up briefly and an audio signal sounds.
To switch off the laser receiver, press and hold the on/off button (19) until all LEDs briefly light up and the display goes out. With the exception of the setting for the display lighting, all settings are saved when the laser receiver is switched off.
If no button on the laser receiver is pressed for approx. 10 min and no laser beam reaches the reception area (1) for 10 min, then the laser receiver will automatically switch itself off to preserve battery life.
In the default factory setting, the rotary laser and the supplied laser receiver are already connected via Bluetooth®. For the existing connection, the Bluetooth® connection indicator (b) appears in the display of the laser receiver.
To reconnect the laser receiver or to connect an additional laser receiver with the rotary laser, press and hold the Bluetooth® button on the rotary laser until the symbol for establishing a connection to the remote control/laser receiver appears in the display of the rotary laser. Then press and hold the X‑axis button (16) and Y‑axis button (15) on the laser receiver until P‑‑ appears in the text display (e).
Confirmation as to whether a connection has successfully been established will be shown on the display of the rotary laser. POK will appear on the text indicator (e) of the laser receiver.
If the connection between the rotary laser and the laser receiver cannot be established, PNK will appear in the text display (e) of the laser receiver and the error message for a failed connection will be shown in the display of the rotary laser. For troubleshooting, consult the operating instructions for the rotary laser.
The position of the laser beam in the reception area (1) is indicated as follows:
- On the display (5) on the front and rear of the laser receiver by means of the "laser beam below centre line" direction indicator (f), the "laser beam above centre line" direction indicator (j) and the centre line indicator (h)
- Optionally, by means of the red "laser beam below centre line" LED direction indicator (4), the blue "laser beam above centre line" LED direction indicator (2) and the green centre line LED (3) on the front of the laser receiver
- By an audio signal (optional).
On the first pass of the laser beam through the reception area (1) a short audio signal always sounds and the red "laser beam below centre line" LED direction indicator (4) and the blue "laser beam above centre line" LED direction indicator (2) briefly light up (even if the audio signal and/or LED direction indicators have been switched off).
Laser receiver too low: If the laser beam hits the upper half of the reception area (1), then the "laser beam above centre line" direction indicator (j) appears in the display.
If the LEDs are switched on, the blue "laser beam above centre line" LED direction indicator (2) lights up.
If the audio signal is switched on, a signal sounds in a slow rhythm.
Move the laser receiver upwards in the direction of the arrow. When the laser beam is close to the centre line, only the tip of the "laser beam above centre line" direction indicator (j) is shown.
Laser receiver too high: If the laser beam hits the lower half of the reception area (1), then the "laser beam below centre line" direction indicator (f) appears in the display.
If the LEDs are switched on, the red "laser beam below centre line" LED direction indicator (4) lights up.
If the audio signal is switched on, a signal sounds in a fast rhythm.
Move the laser receiver downwards in the direction of the arrow. When the laser beam is close to the centre line, only the tip of the "laser beam below centre line" direction indicator (f) is shown.
Laser receiver centred: If the laser beam hits the reception area (1) at the height of the centre line, then the centre line indicator (h) appears in the display.
If the LEDs are switched on, the green centre line LED (3) lights up.
If the audio signal is switched on, a continuous tone sounds.
Memory function of last reception: If the laser receiver is moved so that the laser beam leaves the reception area (1) again, the last displayed direction indicator for "laser beam above centre line" (j) or "laser beam below centre line" (f) flashes for a short time. This indicator can be switched on or off via the settings menu.
The displays (5) on the front and rear of the laser receiver can be illuminated. The display illumination function is switched on:
- When the laser receiver is switched on
- With each press of a button
- If the laser beam moves over the reception area (1).
The display illumination function automatically switches off:
- 30 s after each button press, if no laser beam reaches the reception area
- 2 min after the last button press and if the position of the laser beam in the reception area does not change.
The display illumination can be switched off in the settings menu.
The setting for display illumination is not saved when the laser receiver is switched off. After switching on the laser receiver, the display illumination is always switched on.
