Make sure the equipment is connected to 13.8V power supply and proper antenna
adjusted for working band. If external headphones are preferred they can be
connected via front panel 3.5mm jack 6 on fig.1. External loud speaker can be
connected via 3.5mm jack 7 fig.2 on real panel. For convenient work the radio body
can be tilted by supplied flipping bail on bottom lid.
