Installing Battery:

The Laser Collimator is powered by one CR2032 battery (Not Included). When the laser beam starts to dim or completely fades, it’s time to replace the battery. To do so, unscrew the knurled battery compartment cap at the top of the collimator. With a knife tip or the end of a paper clip, lift the edge of the expired battery out. Insert a fresh CR2032 battery with the positive (+) side up. Then replace the cap

Dual Language Instruction

This adjustment tool can be used in all 1.25" focusers. We provide you with precise instructions in German and English, with a step-by-step explanation of how to adjust a Newtonian telescope using this laser unit. So, even if you are a newcomer to amateur astronomy, it is very simple to get the optimum performance out of your telescope.

Recalibrating the Laser Collimator

• The Laser Collimator has been precisely aligned at the factory and can be used directly, unless a strong impact which require recalibration.
• You need a holder that is required is a suitable "V" block to rest the collimator body in so that it can be rotated through 360 degrees. To check the calibration, the laser should be rested in the jig aimed at a wall about 6 metres (20 ft) away and slowly rotated. If the laser dot on the wall describes a circle, then the collimator is out of calibration.

Care and Maintenance:

Your Laser Collimator is manufactured of the highest quality components. The internal laser diode is precision aligned with the mechanical axis of the housing at the factory and tested to meet stringent specifications. Like all electronic equipment, the Laser Collimator should be handled with care. If it is dropped or handled roughly, the internal laser could become misaligned. Avoid exposing the collimator to water, dust, heat.
