What are these symbols in a schematic.

[Rehmat karim]

Hello everyone.
I am new to electronics therefore I am not an expert. I was studying a metal detector schematic, I need help in few things in the attached schematic, Kindly tell me what are these symbols, what they mean and if someone want to build this circuit what components would be used in place. I have marked the areas red kindly help me if there is any expert out there. thanks you very much.

most of them are really straight forward
so come on make an effort and tell me what you think they might stand for

Can't tell what are these, B,C D F and H confuses me. If you know the answer please tell me.

 

[davenn]

so what do the tags on C, D, and H say ?
they are very clear in their wording ..... what does that tell you ?

cant make out clearly what B and F are ... the diagram is too small and unclear
look like some sort of link alternatives

C D and H says they are voltage sources, but what about the Point G it also showing voltage points.

C D and H says they are voltage sources,

exactly .... that wasn't too difficult was it

but what about the Point G it also showing voltage points.

all points like G and there is a lot of them with an arrow pointing up and a voltage marking tell you they are
going to a voltage source that supplies the indicated marking

so, can you see where G and ones with the same marking go to ?

B is a switchable jumper that can switch the meter between two of the voltage sources
the 9V one (H) and the 5.6V one (C)

Hahaha Thank you. You cleared my confusion. Point F is still need answer.

F is a double pole double throw switch.

Thank you Steve.
