We have a Philips Cordless

Question

We have a Philips Cordless phone CD4450 We have 4 phones and one of them will not ring. I tried to get the ringer to workr but goofed up some how and went into Spanish from English. It will not get out of the Spanish and I still haven't figured out how to get the phone to ring. Also, Is there some way to set the phone for remote reception. I will be out of town over the weekend & would like to be able to check any calls that will come in. Thank oyu.
