On the right hand side, just above the mic connector is a column of 3 blue buttons, which control Selcall sending, scanning and the power switch. To the left of those are 3 LEDs, a red one to indicate when the radio is transmitting, a yellow one for received signal, and a green one for power. To the left of the display are the volume and mute controls, which are standard rotary pots, and finally, there is a small speaker for received audio on the left hand side of the panel. As for the construction, these things are built like tanks. Inside, the PCBs swing out for easy access.
Construction is neat and well laid out.
Definitely a design that lends itself to easy modification. This keeps the operation simple for its intended purpose, but is somewhat less flexible for amateurs. The receiver is not as sensitive as dedicated amateur rigs, but on the other hand, it is very tolerant of out of band rubbish, such as the paging transmitters on 148 MHz. It is obviously commercial spec here, where a small amount of sensitivity is traded off for much improved interference rejection. The FM92 is still capable of receiving good signals from the SO-35 satellite on a non optimal antenna.
