IntroductionGENERALAll Gammex FOCUS - REMOTE CONTROL (GREEN) Laser AlignmentSystems provide an optical aid for rapid and accurate patient positioningand repositioning for therapy and simulator machines.TECHNICAL DESCRIPTIONVarious combinations of the GLD-500-RC crosshair FOCUS - REMOTECONTROL (GREEN) and the GLD-300-RC sagittal (straight line)FOCUS - REMOTE CONTROL (GREEN) are used with differentsystems. The GLD-500-RC lasers, mounted on each side, beamcrosshairs along the X-axis. The crosshair GLD-500-RC laser, mountedon the ceiling, beams a crosshair vertically along the Z-axis. The SagittalGLD-300-RC laser beams a straight line in the Z-Y plane.Installation RequirementsELECTRICALEach laser is provided with a universal power supply (transformer) withan input of 100 to 240 volts at 50 to 60 Hz. The universal power supplyplugs into a wall outlet with 4 interchangeable “snap-in” plugs to fit mostoutlets. A 1.2 meter (4 foot) power cord supplies 12 volt dc power to thelaser with a screw-on power plugTOOLS NEEDEDIn addition to some basic tools, such as screwdrivers, hammer andladder; you will need an electric hammer drill, plumb bob, level, waterlevel, masking tape and 15M (50 feet) of string. (The mountinghardware, a 1/4-20 tap and tap drill, and 4 hex (Allen) wrenches (.050”,1/8”, 3/32”, & 5/64”) are included with the lasers.)CAUTION: The location of the lasers is determined in relation to thetherapy machine’s crosshair and isocenter. Before installing lasers, askthe physicist to verify that the field light aligns with the machine’sisocenter. Figure 1.Pre-InstallationInstallation and User Guide7
Figure 2Use a water level to line upthe laser exit reference pointat the height of isocenter.Pre-InstallationFocus - Remote Control (Green) Diode Laser8
Pre-InstallationUse a water level, see Fig. 2, to line up the laser exit referencepoint at the height of isocenter.PREPARING THE ROOM1. Unpack each laser, add the cord and plug into a wall outlet.2. Turn the linear accelerator lamp on.3. Set gantry and collimator to 0° and level the collimator.4. Lower the table as low as possible.COLLIMATOR CROSSHAIR ACCURACYThe collimator-projected crosshair is used as a referencewhen determining the laser locations. The light field shouldcoincide with isocenter, the gantry should be level and, ifcollimator crosshair displacement exists, it should becompensated for.1. Project a crosshair onto a piece of paper taped to the tableand mark the center with a dot.2. Rotate through 360° and mark the center again.3. If there is a difference between the two dots, find thecenter of the distance between the two dots. Mark thispoint and use this point as the crosshair center referencepoint. Use this point to line up the laser.USING THE WATER LEVELUse a water level, see Fig. 2, to determine the height of thelaser exit reference point when installing lasers in a simulatorroom or in a room with angled walls. In standard treatmentrooms, the water level should also be used to verify the laserlocation.1. Raise the table to the front pointer (isocenter).2. Remove caps on ends of water level and remove airbubbles.3. Line up with the table edge and with the wall. Figure 24. The water line on the wall indicates the horizontal axis ofthe laser exit reference point.Use a level to verify:• Gantry is level each time it is rotated• Template is placedaccurately on wall• Crosshairs on wall are at 90° anglesPre-InstallationInstallation and User Guide9

Remote ControlRemote control is a radio communication feature that allows the operator to align asmany as five lasers with one hand-held controller. Each Focus laser has a separate wallmounted receiver that communicates with the operator's transmitter. The receivers andtransmitter all have an ID switch. The ID switch sets the identification number for thesystem. This allows different rooms to operate remote control lasers in close proximitywithout interference. All remote control receivers in a room will have the same IDnumber. Different rooms will have different ID numbers. To communicate properly, thetransmitter ID must be set to match the receiver IDs of all of the laser receivers in asystem.SETTING THE TRANSMITTER IDThe transmitter ID switch is accessiblethrough the battery compartment. To settransmitter identification, remove thebattery cover and locate the switch. It willhave three small toggles labeled 1, 2, and3. Each toggle has an "on" position andan "off" position. For ID one, set switch 1"on" and all other switches "off". For IDtwo, set switch 2 "on" and all otherswitches "off". ID three has 1 and 2 "on"and 3 "off". ID four has 3 "on" and all otherswitches "off". This sequence can continueup to ID seven which has all switches "on".The following table gives all of thecombinations.Operator ControlsFocus - Remote Control (Green) Diode Laser14
ID SWITCH 1 SWITCH 2 SWITCH 30 OFF OFF OFF1 ON OFF OFF2 OFF ON OFF3 ON ON OFF4 OFF OFF ON5 ON OFF ON6 OFF ON ON7 ON ON ONOperator ControlsInstallation and User Guide15SETTING THE RECEIVER LASER NUMBERThe other switch on the bottom of the receiver selects the number for the laser. Thiscorresponds directly to the laser number selection on the hand held transmitter.Each receiver has a switch with five positions. These positions represent the number of thelaser that the receiver controls. If we move the first lever down and the rest up, then that makesthe receiver number one, and the laser connected to it is also number one. The second leverstands for number two, and the third lever stands for number three. Only one lever may be inthe down position for any given receiver. The other four switch levers must be up. Verify that the id switch settings on all receivers in asystem match the transmitter ID switch setting.

Push the unlock button to activatethe transmitter. The transmitter lightshould turn on.3. On the transmitter, select thenumber of the laser that youwish to align.The remote control receivers can bemounted to a wall, ceiling or otherappropriate surface using two #8screws (not included), spaced 1.5”apart. Keyhole slots in the back of thereceivers will then fit over the screwheads and hold the receivers in place.The receivers can be damaged byradiation and should therefore bemounted outside of the radiation field.Once mounted, connect each receiverto its corresponding laser with theincluded cable. The remote control transmitter can bedamaged by radiation and should notbe left in the radiation field.

Focus - Remote Control (Green) Laser Positioning AdjustmentsFigure 6 shows schematically the positioning adjustments available on the FOCUS -REMOTE CONTROL (GREEN).Figure 7 shows the different adjustments available on theFOCUS - REMOTE CONTROL (GREEN). The FOCUS - REMOTE CONTROL (GREEN)has both coarse and fine horizontal position adjustments. The remote control fineadjustment has limited range and is factory set in the middle of the range. If the limit of therange is reached, run the remote control a short distance in the opposite direction. Then usethe coarse adjustment to move close to the desired position. Finally use the remote control fine adjustment to accurately position the crosshair.Focus, angularity, and line curvature are factory set and should notrequire adjustments at installation. Adjustments are available, ifrequired, and are explained on the following pages.Laser Positioning AdjustmentsInstallation and User Guide23
Laser Coarse Rotational PositioningThe FOCUS - REMOTE CONTROL (GREEN)optics can berotated for coarse horizontal positioning. To make this adjustment,loosen the setscrew as shown using a .050 hex wrench. The entireoptics assembly can be rotated by hand, left or right, to move thecrosshair horizontally. This is a very coarse adjustment. Thesetscrew must then be re-tightened. A fine-tuning adjustment canthen be used to accurately position the crosshair.Laser Positioning AdjustmentsFocus - Remote Control (Green) Diode Laser24
Curvature AdjustmentsThe line curvature is factory set. Adjustment should not benecessary. If needed, the 2 adjustments on the right handside of the optics are used to straighten either line of thecrosshair. Use a 3/32" hex wrench. Figure 7Figure 7A.

The two-projected laser crosshairs should line up on the paper (Figure 13).With the gantry at 0° (Leveled and Set at 0°) use a front pointer (Figure 14) to verify thatboth side lasers hit isocenter. If there is not a front pointer, raise the table to isocenterand project a crosshair on the table to verify that the side lasers hit isocenter.ADJUSTMENTSIn a new installation some building movements can be expected. In most cases the fineadjustments made by pushing the remote control buttons as shown on pages 16 to 19should be sufficient to make any adjustments.The remote control adjustments have limited range. If the remote control adjustment isat the end of the range, run it a short distance in the opposite direction. Use a coarseadjustment to come close to the desired position and use the remote control adjustmentto zero in.Pages 20 through 30 outline various adjustments available on the FOCUS - REMOTECONTROL (GREEN). In most cases only the remote control horizontal and verticaladjustments will be needed.Laser Calibration and AdjustmentsInstallation and User Guide41
RepairWarning - Use only repair parts specified by Gammex. Some parts may be similar, but mayresult in unit drifting out of alignment, early failure or being out of compliance with laserregulations.See pages 43 through 48 for FOCUS - REMOTE CONTROL (GREEN) repair instructions.TroubleshootingPROBLEM POSSIBLE CAUSE POSSIBLE REMEDYNO LASER LIGHT Wall switch not on.

Use voltmeter to measure thevoltage output of the powersupply wall plug. If voltage lessthan 11 or greater than 13 VDC,the power supply will need tobe replaced. Call GammexSales and Service forassistance.INTERMITTENT LASER Use voltmeter and check powersupply. See above.TroubleshootingFocus - Remote Control (Green) Diode Laser42Maintenance & CleaningOnce installed, Gammex Lasers require no maintenance other than cleaning of mirrors,beam splitters, and lenses according to standard optical practices. Occasional outsidedusting of the green plastic window in the cover may be necessary. The window is verydelicate. Use only a camera lens brush or other soft brush for this purpose. Clean otheroutside surfaces of the laser, receiver and transmitter with a soft cloth slightly moistenedwith water or a mild detergent solution, then wipe the surface with a dry cloth. Do not useany type of abrasive pad, scouring powder or chemical solvent such as thinner, benzene,alcohol or disposable wipes as these may damage the finish. Should a laser fail tofunction properly, contact Gammex Sales and Service.
