Topcon Measuring Tools & Sensors - Answered Questions & Fixed Issues

If changing the batteries did not solve the problem, you could try resetting the remote. To do this, remove the batteries and hold down any button on the remote for about 5-10 seconds. Then, reinsert the batteries and try turning the remote on again. If the remote still does not work, it may be damaged and need to be replaced.

No one will tell you exactly. There could be several variants, you have to disassemble the device and look at it. Maybe there is something wrong with the circuit board, or with the contacts, or the laser transmitter has burned out and needs to be replaced.

Hope This Helps

There are 2 small screws holding the rotating head motor in place. Likely you just need to loosen these screws, and adjust the motor position and retighten.

On what?

Hello, have you already fixed it?

Hola, ya lo has solucionado?

Either the laser diode has failed, or the main circuit board is not activating the laser. Either way it's an expensive repair, and it will have to go to a service shop to get looked at. I recommend finding a shop that gives free estimate, as you may not want to proceed with the repair.

Sound like the laser diode is failing. It's power is likely just strong enough to get the level position right, then dims as it runs. The unit, no longer seeing the laser, decides it's out of level and stops. Or the oil in the compensator is leaking, and the same process is happening. Unfortunately the replacement part is not economical to replace.

This is not a battery problem. It likely levels to the back corner, then to the front corner then roughly back to the middle and spins at about 150 rpm and the lights on the front blink. There are a couple things that can cause this. the most common is the the compensator cant find the laser. 5 screws hold the main housing on to the base. Remove the housing and inspect. if the internals are coated in oil, then the unit is done. The replacement part is too expensive. If the inside is dry, there is a small circuit board on the left side of the metal compensator frame. Resolder the pins in the board, and the connector going to the side board, located on the main board. about 30% of the time, this will get the laser running again. If not, the laser diode is likely dead, and it's not repairable.

Only tech's at topcon shops (or former techs) have thoes, and are usually unwilling to share. It's not like a car, where aftermarket people make manuals and sell them. If you tell me what you need, i may be able to help you. While i no longer have the manual, I've worked on literally hundreds of them.

3 D cells. Open the battery compartment, and insert them as indicated on the battery openings.

If it came from alkaline batteries (Duracells, etc) flush the battery compartment with an acidic cleaner, like an orange cleaner. This will help neutralize the alkaline left behind. Clean that out as best you can. Dont put too much in the battery compartment or it will contaminate the laser internals. Clean the battery contacts, and you should be good to go. if not, then likely the main board has been damaged, and you should get it looked at. They can usually be cleaned up, but it may require a new board.
