Just work it through the assets/depreciation section and follow the prompts making sure you read the entire screen first, so you make the correct selections.
If you are offered the 50% special depreciation allowance, I suggest you take it. That way, you can depreciate up to $850 the first year. Otherwise, on a $1700 cost you'll be depreciating $340 a year over 5 years, and that's just not worth the time to me. (It may be okay with you however.)
