Good product, efficient and clever, perfectible manual

Negative:
I find the logic of the time zone switch + summer / winter puzzling. I thought the switch changed the local time relative to GMT / UTC but it is not the only time "World" is affected, reached its destination or was change / winter it is not enough turning the switch must be re-set the local time.
The record has shortcomings, it does not specify, for example:
- That the hour of awakening does not refer to local time but at the time of the selected time, better knowledge :-(
- How to display the temperature in ° C instead of ° F (default), the "secret" is to change the configuration of the spacing of the AM stations from October to September KHz, it can not be invented!
