# Check Trouble Condition
In order to check and clear troubles on the DSC PC1555 security system you will need to enter \*2 on the keypad. At that point, a totally different number should show up. Once you get this number, please document it and refer to the trouble conditions which you can find below. Also, please click the link at the bottom of the page to see the DSC trouble condition and solution guide in PDF format below. This PDF document can help you navigate the issue you are having with your panel and help you to DIY solve your problem.
Light 1 - Service Required - Press the 1 key for more info.
If the number 1 light stays on, it means the Main panel battery needs to be swapped out.
