The Bluetooth® range may be signi- ficantly weaker inside closed rooms and through metallic barriers (e.g. walls, shelving units, cases, etc.). For clear identification of your laser receiver, see the serial number (12) on the type plate. Assembly Inserting/Changing the Batteries Alkali-manganese batteries are recommended for the laser receiver. Turn the locking mechanism(14) of the battery compart- ment cover into position (e.g. using a coin). Open the battery compartment cover(13) and insert the batteries. When inserting the batteries, ensure that the polarity is cor- rect according to the illustration on the inside of the battery compartment. Close the battery compartment cover(13) and turn the lock- ing mechanism(14) of the battery compartment cover into position . The battery indicator(i) shows the state of charge of the bat- teries of the laser receiver: Indicator Capacity 50 − 100% 5 − 50% 2 − 5% 1 609 92A 7M6 | (12.05.2022) Bosch Power ToolsEnglish | 17 Indicator Capacity 0 − 2% Always replace all the batteries at the same time. Only use batteries from the same manufacturer and which have the same capacity. u Take the batteries out of the laser receiver when you are not using it for a prolonged period of time. The bat- teries can corrode and self-discharge during prolonged storage in the laser receiver. Rotary Laser Battery Charge Indicator The battery charge indicator(a) shows the state of charge of the battery pack/batteries of the rotary laser, provided that the rotary laser is switched on and a Bluetooth® connection has been established between the laser receiver and the rotary laser. Indicator Capacity 60 − 100% 30 − 60% 5 − 30% 0 − 5% Operation Starting operation u Protect the laser receiver against moisture and direct sunlight. u Do not subject the laser receiver to extreme temperat- ures 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 ad- just to the ambient temperature before putting it into op- eration. In case of extreme temperatures or variations in temperature, the accuracy of the laser receiver can be im- paired. u Keep the work area free from obstacles that could re- flect or obstruct the laser beam. For example, cover any reflective or shiny surfaces. Do not measure through panes of glass or similar materials. The meas- urements may be distorted by a reflected or obstructed laser beam. Setting up the laser receiver (seefigureA) 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. Switching On/Off u 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. 10min and no laser beam reaches the reception area(1) for 10min, then the laser receiver will automatically switch it- self off to preserve battery life. Connection to the Rotary Laser In the default factory setting, the rotary laser and the sup- plied 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 es- tablishing 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 untilP‑‑ 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 re- ceiver 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 instruc- tions for the rotary laser. Direction indicators The position of the laser beam in the reception area(1) is in- dicated as follows: – On the display(5) on the front and rear of the laser re- ceiver by means of the "laser beam below centre line" dir- ection 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 Bosch Power Tools 1 609 92A 7M6 | (12.05.2022)18 | English 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 ar- row. 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 ar- row. 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. Relative height indicator (seefigureB) If the laser beam hits the reception area(1), the clearance between the laser beam and the centre line of the laser re- ceiver is shown in the text display(e) as an absolute value. The measuring unit for the height indicator can be changed in the settings menu ("mm" or "in"). Display illumination 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: – 30s after each button press, if no laser beam reaches the reception area – 2min 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 re- ceiver, the display illumination is always switched on. Settings Selecting the setting of the centre line indicator You can specify the accuracy with which the position of the laser beam is indicated as "centred" on the reception area(1). The current setting for the centre line indicator(c) can be seen in the indicator for reception accuracy. To change the reception accuracy, press the button for ad- justing the reception accuracy(18) as many times as needed for the required setting to be shown in the display. With each press of the button for adjusting the reception ac- curacy, the respective value for the reception accuracy ap- pears in the text display(e) for a short time. The setting for reception accuracy is saved when the tool is switched off. Laser Beam Indicator Audio Signal The position of the laser beam on the reception area (1) can also be indicated by an audio signal. The volume level can be changed or the audio signal switched off. To change the volume level or switch off the audio signal, push the audio signal button (20) until the required volume level is indicated on the display. At a low volume, the audio signal indicator(g) appears on the display with one bar; at a high volume, the indicator appears with three bars. When the audio signal is switched off, the indicator goes out. Independent of the audio signal setting, a short beep sounds at low volume level when the laser beam first makes contact with the reception area(1). The setting for the audio signal is saved when the laser re- ceiver is switched off. Settings menu To call up the settings menu: Briefly press the X-axis button(16) and the Y-axis button(15) on the laser receiver at the same time. To change the setting within a submenu: Press the X-axis button(16) or the Y-axis button(15) to switch between the settings. The last selected setting is automatically saved when exiting the menu. To change the submenu: Briefly press the CenterFind mode button(17) to move to the next submenu. To exit the settings menu: Press and hold the CenterFind mode button(17) until the settings menu closes. Alternat- ively, the settings menu is automatically closed approxim- ately 10seconds after the last press of a button. The following submenus are available: – Unit of measurement of the relative height indicator: When calling up the unit of measurement menu, the cur- rently selected unit of measurement is shown in the text display(e), while the available units of measurement are shown in the unit of measurement indicator(d) above it. 1 609 92A 7M6 | (12.05.2022) Bosch Power ToolsEnglish | 19 – LED direction indicators (LED): The 3 LED direction indicators(2), (4) and (3) can be adjusted with regard to their brightness or switched off. The LEDs light up in their selected setting. – Display lighting (LIT): The display lighting can be switched on (green LED lights up) or switched off (red LED lights up). – Memory function for last reception (MEM): The indic- ator for the direction in which the laser beam has left the reception area can be switched on (green LED lights up) or switched off (red LED lights up). – Centre functions (CF/CL) (LR65G): You can choose between CenterFind (CF) mode and CenterLock (CL) mode. The current mode appears in the text display(e). With the exception of the setting for the display lighting, all settings are saved when the laser receiver is switched off. Functions CenterFind mode (see figureC) In CenterFind mode, the rotary laser automatically attempts to align the laser beam to the centre line of the laser receiver by moving the rotation head up and down. If the rotary laser is in the horizontal position, the laser beam can be aligned in relation to the X-axis of the rotary laser, to the Y-axis or to both axes at the same time (see "In- clination determination with CenterFind mode (see figureD)", page19). If the rotary laser is in the vertical po- sition, only alignment to the Y-axis is possible. Start CenterFind mode:

Position the rotary laser and laser receiver so that the laser receiver is situated in the direction of the X-axis or the Y-axis of the rotary laser. Align the laser receiver so that the re- quired axis is at a right angle to the reception area(1). If the laser beam is aligned to both axes, then place a laser receiver connected to the rotary laser in the direction of the X- and Y-axis respectively. Each laser receiver must be situ- ated within the pivoting range of ±8.5% of the rotary laser. Switch on the rotary laser in rotational operation. In the settings menu of the laser receiver, the centre function must be put in CenterLock (CL) mode. When aligning to two axes of the rotary laser, this applies to both laser receivers. To start the CenterLock mode for the X‑axis, either press and hold the CenterFind(17) mode button, or press and hold the CenterFind(17) mode button, together with the X‑axis button(16). To start the CenterLock mode for the Y-axis, press and hold the CenterFind(17) mode button, together with the Y‑axis button(15). Should the laser beam be aligned to both axes at the same time, CenterLock mode must be started separately on each laser receiver. Following the start of CenterLock mode, the rotary head on the rotary laser moves up and down. During the search pro- cess, CLX (X‑axis) or CLY (Y‑axis) appears in the text display(e). If the laser beam hits the reception area(1) at the height of the centre line of the laser receiver, the centre line indicator(h) and the text display(e) LOC will appear. The CenterLock symbol is displayed on the rotary laser on the start screen for the corresponding axis. In the event of changes to the position of the laser receiver or rotary laser, the inclination is automatically adjusted on the rotary laser. u Take great care when working with the CenterLock mode that rotary lasers and laser receivers are not moved unintentionally. Incorrect measurements can arise from the automatic adjustment of the inclination with every change of position. Cancelling CenterLock mode: To cancel or end the CenterLock mode, press and hold the CenterFind mode button(17). If the laser beam was already successfully aligned with the centre line of the laser receiver at this point, the set inclination remains on the rotary laser even when CenterLock mode is cancelled. Troubleshooting: If the laser beam was unable to find the centre line of the laser receiver within 2min (no matter whether at the start of the mode or after changes to position), ERR appears in the text display(e) and all LED direction indicators light up. Press any button on the rotary laser and one on the laser re- ceiver to close the error messages. Reposition the rotary laser and laser receiver so that the laser receiver is situated within the pivoting range of ±8.5% of the rotary laser. En- sure that the laser receiver is aligned to the X-axis or Y-axis so that the laser beam can pass through the reception area(1) horizontally. Then restart the CenterLock mode. If both axes of the rotary laser should be aligned to a laser re- ceiver, the same centre function must be set on both laser receivers. A combination of CenterLock mode andCenterFind mode is not possible. IfCenterFind mode is already set on one axis andCenterLock mode is started on the other axis,ERR andCF will appear alternately in the text display(e). Select CenterLock mode on both laser receivers and re-start the function. Anti-strobe protection filter The laser receiver has electronic filters for strobe light. The filters protect against, for example, interference from the warning lights of construction machinery. Working Advice Aligning with the spirit level The laser receiver can be aligned vertically (plumb line) with the spirit level(7). If a laser receiver is mounted at an angle, it will give incorrect measurements. 1 609 92A 7M6 | (12.05.2022) Bosch Power ToolsEnglish | 21 Marking You can mark the position of the laser beam at the centre mark(9) on the left and right of the laser receiver when the beam hits the centre of the reception area(1). When marking, take care to align the laser receiver so that it is exactly vertical (with a horizontal laser beam) or horizontal (with a vertical laser beam), as otherwise the marks are off- set with respect to the laser beam. Attaching using the holder (seefigureE) You can use the holder(23) to attach the laser receiver to a measuring rod(25) (accessory) as well as to other auxiliary tools with a width of up to 65mm. Screw the holder(23) to the mount(11) on the rear side of the laser receiver with the fastening screw(26). Loosen the rotary knob(24) on the holder, slide the holder onto the measuring rod(25) and retighten the rotary knob(24). You can use the spirit level(21) to ensure that the holder(23) is horizontally aligned along with the laser re- ceiver. If the laser receiver is mounted at an angle, it will give incorrect measurements. The centre line reference(22) on the holder is situated at the same height as the centre marking(9) and can be used for marking the laser beam. Attaching using a magnet (see figure F) If an attachment is not required to be especially secure, the laser receiver can be attached to steel parts using the magnets(10). Rectifying errors Text display (e) Problem Corrective measures PNK Failed to establish Bluetooth® connec- tion to the GRL600CHV or GRL650CHVG rotary laser Briefly press the on/off button on the rotary laser to close the error message.
