The maximum volume of ring tones - there are nine available - and the built-in loudspeaker of the base station of the answering machine, however, are only moderately loud. It rings even the handset, but not the base station. The handset also flashes when a call (can be disabled). The AB may also be heard via the handset.
Commissioning, programming the phone book and the three quick-dial buttons I made for law and it worked without any problems. The accompanying manual (15 x 10.5 cm) but virtually useless because of too little work, they've downloaded and read on my PC.
Power consumption is indeed low and the AC adapter is quite small, the cables are 1.8 meters long. What is not mentioned in the manual, the handset commercially available batteries are used. The battery cover must be pushed here from top to bottom.
All in all, mother very happy with the new phone. I still have a few pictures uploaded it.
