you will have to use a vacuum bulb or vacuum desoldering tool to unsolder it. We cannot

stress enough that you need to check the orientation of the parts before you solder them. The

Eggtimer TRS Limited Warranty does not cover damage to a component while attempting to

unsolder it, so make take your time and make sure you get it right before you solder.

Check Your Power Supply

Make sure that you are using one of the recommended batteries to test with. Make sure that

you have the polarity correct: The RED wires must go to the “+” side and the BLACK wires

must go to the “-“ side. Your battery connector must be soldered to the pads marked “BATT”

+ and -. The “DPWR” pads are for the deployment power… if you solder your battery to

them, it’s not going to do anything at all since that only powers the deployment side.

If It Still Doesn’t Work…

There is, of course, always an outside chance that you have a bad component. We test each PC

board and the surface mounted components before they leave us. Nevertheless, it is always

possible that something may be wrong; there may be a bridge on the PC board itself, etc. If

you have gone through all of the troubleshooting steps and the board still doesn’t work, let us

know at support@eggtimerrocketry.com . A high-resolution picture (5 megapixel or better) of

both sides of your circuit board and a description of the problem would be very helpful…
