Insert/Exchange Batteries; Emergency Operation In The Case Of A Power Failure - TIPTEL 195 Operating Instructions Manual

Initial operation

Insert/exchange batteries

The batteries prevent your tiptel 195 from a loss of data in the case of a power failure. The bat-
tery compartment provides a subdivision:
- Two batteries are for the "text memory" supply power for the electronic telephone book, i. e.
telephone numbers, addresses, appointments, time control and settings.
- Three additional batteries in addition to the two "text memory" batteries allow you to hold tele-
phone conversations even in the case of a power failure.
1. Press the two clamps to open the battery compartment
2. Ensure the correct polarity when inserting the batteries (type "AAA" = microcells 1.5V)
3. Close the battery compartment.
4. When pressing the buttons
symbol in the display informs you about the current battery charge status.
The battery symbol in the display will blink in time when the batteries are nearly discharged and
need to be exchanged. In this case, exchange the batteries as described under point 1 – 4 with-
out unplugging the 230 V AC adapter. As long as the telephone is connected to the power sup-
ply, your data will be retained. The content of the text memory will only be lost if the device is
without any power supply for about 1 minute.
Please observe that:
1. Discharged batteries may be subject to leakage and thus damage your telephone. The batte-
ries should be exchanged in time and then disposed of environmentally. We recommend alka-
line-manganese batteries.
2. Battery lifecycle:
- If only the two batteries for the text memory are inserted, the data retention period after a
power failure is 5 years.
- If all five batteries are inserted, the telephone emergency operation is possible for about 24
hours. In addition, the text memory will be retained for about 2 weeks.
3. When the display indicates the low battery capacity, all batteries should be exchanged at once.

Emergency operation in the case of a power failure

If the device is operated without power supply, the following functions remain activated:
- manual off-hook dialling (the display is turned off)
- ringing signal for incoming calls.
The tiptel 195 remains fully functional in the event of a power failure only if all 5 batteries have
been inserted.
