apologies for the laziness in backreading if someone already brought this up.

1. Need ko pa ba alisin sa power source everytime i turn off the engine?

2. I rarely park in the open, pero siyempre hindi maiiwasan. Is it harmful for the camera if parked under the sun?

3. Asa loob pala battery ng DP 220, any tips to prolong the camera life? do's and donts?
