Need help for AOR AR16B
 

Dear Sirs ,

We are members of a Children's Radio Club and we are pleased to say that we
use some of your devices.

I would like to ask you to help me in the repairs of radioscanner AR16B
(Ser.#050634).



We have the following problems.

1.. In all modulation modes when buttons "Start", "Func", "Moni" are
pressed all the readings in the display disappear.
2.. NFM mode does not work. S-meter shows the presence of the signal but
there is no sound in the loud speaker even when the "Moni" button is
pressed.
In WFM and AM modes everything works OK besides the defect indicated in item
1.

What element's might not work properly?

Could you possibly send me the schematic diagram of AR16B?

How made reset processor of AR16B ?

Thank you in advance.



Respectfully yours,

Sergey V. Martynov.
