Ideal for people with hearing impairment and for all users looking for a phone with amplified sound.

• Extra audio boost button
  Thanks to the audio boost key, ideally placed on the side of the handset, you can increase the volume during a call without having to put the handset down to adjust the volume.
  Practical especially in noisy environments: The maximum amplification is +35 dB.
• Call-block function
  Thanks to two different call-block functions, nuisance calls are a thing of the past:
  A manual mode to block up to 100 numbers during or after a call, and an automatic mode so that calls are only accepted from stored or VIP numbers.
• The plus in operating comfort
  The handset has an extra-large keypad and three easy-to-use direct dial keys for frequently used numbers.
  This makes the BigTel 1580 particularly suitable for people with impaired vision, as well as for people with motor impairments, such as trembling hands.
• High-quality display
  The easy-to-read, large display provides clear contrasts and a bright, pale blue backlight.
  In addition, the large letters and numbers ensure very good legibility of names and phone numbers, and particularly easy and quick operation of the menu.
• Call answering & direct dialling
  When the phone rings and you can’t find your handset, you can answer the call directly from the base in handsfree mode.
  With the three direct dial keys you can call the most important phone numbers, from the base in handsfree mode, and also from the handset with just one touch.
• Intuitive answering machine
  The answering machine integrated in the base station can be operated intuitively and comfortably thanks to large buttons for each function.
  The message counter with large digits shows you at a glance whether you have any messages at all and how many you have.
