Minor grey rust on battery contacts - no issue, cleaned
Clock Light works only when pressed
Battery operated 5x 1.5V batteries
If you wish to have permanent light you may
substitute somehow 1.5V battery for clock for constant
power supply. Clock has separate battery 1.5 v other batteries go for radio.
It is not designed to do this - just a "discussion" for enthusiast.
Than you may press constantly light button to have constant light
it is just abstract suggestion ...
