_Don't_ use condensers with paper dielectrics for an amplifier receiving set or it will be noisy.
_Don't_ expect as good results with a loop aerial, or when using the bed springs, as an out-door aerial will give you.
_Don't_ use an amplifier having a plate potential of less than 100 volts for the last step where a loud speaker is to be used.
_Don't_ try to a.s.semble a set if you don't know the difference between a binding post and a blue print. Buy a set ready to use.
_Don't_ expect to get Arlington time signals and the big cableless stations if your receiver is made for short wave lengths.
_Don't_ take your headphones apart. You are just as apt to spoil them as you would a watch.
_Don't_ expect to get results with a Bell telephone receiver.
_Don't_ forget that there are other operators using the ether besides yourself.
_Don't_ let your B battery get damp and don't let it freeze.
_Don't_ try to recharge your B battery unless it is constructed for the purpose.
STORAGE BATTERY DON'TS
_Don't_ connect a source of alternating current direct to your storage battery. You have to use a rectifier.
_Don't_ connect the positive lead of the charging circuit with the negative terminal of your storage battery.
_Don't_ let the electrolyte get lower than the tops of the plates of your storage battery.
_Don't_ fail to look after the condition of your storage battery once in a while.
_Don't_ buy a storage battery that gives less than 6 volts for heating the filament.
_Don't_ fail to keep the specific gravity of the electrolyte of your storage battery between 1.225 and 1.300 Baume. This you can do with a hydrometer.
_Don't_ fail to recharge your storage battery when the hydrometer shows that the specific gravity of the electrolyte is close to 1.225.
_Don't_ keep charging the battery after the hydrometer shows that the specific gravity is 1.285.
_Don't_ let the storage battery freeze.
_Don't_ let it stand for longer than a month without using unless you charge it.
_Don't_ monkey with the storage battery except to add a little sulphuric acid to the electrolyte from time to time. If anything goes wrong with it better take it to a service station and let the expert do it.
EXTRA DON'TS
_Don't_ think you have an up-to-date transmitting station unless you are using C.W.
_Don't_ use a wire from your lightning switch down to the outside ground that is smaller than No. _4_.
_Don't_ try to operate your spark coil with 110-volt direct lighting current without connecting in a rheostat.
_Don't_ try to operate your spark coil with 110-volt alternating lighting current without connecting in an electrolytic interrupter.
_Don't_ try to operate an alternating current power transformer with 110-volt direct current without connecting in an electrolytic interruptor.
_Don't_--no never--connect one side of the spark gap to the aerial wire and the other side of the spark gap to the ground. The Government won't have it--that's all.
_Don't_ try to tune your transmitter to send out waves of given length by guesswork. Use a wavemeter.
_Don't_ use _hard fiber_ for panels. It is a very poor insulator where high frequency currents are used.
_Don't_ think you are the only one who doesn't know all about wireless. Wireless is a very complex art and there are many things that those experienced have still to learn.
THE END.
