The Philips XL4902S/22 is a landline phone, designed to make it convenient to use for both families and senior citizens. With a talk time of 16 hours, you won't have to put your handset back on the charging dock after each call. If the battery runs out of power anyway after a while, the LED indicator will light up. The handset's buttons and screen are large and clearly legible, so you can effortlessly select the contact you need. If you have trouble understanding him or her, you can activate the audio boost function. On top of that, people wearing hearing aids can couple the phone with the hearing aid to reduce noise interference.
