The Memory Card
Issue 4 October 2008 15

Charging and Discharging

The batteries can be charged and discharged hundreds of times. If the operating time (i.e. talk
and standby time) is significantly shorter than usual, then it is time to replace the batteries.
To maintain optimum operating time, the batteries should be discharged from time to time by not
placing the telephone in the charger but leaving it switched on until it switches itself off.
Extreme temperatures can influence the charging capability of the batteries.
The Memory Card

Using the Avaya 3711 with/without a memory card

Your Avaya 3711 is fully operational when you use it for the first time even if you have not fitted
it with a memory card. If you have already used a memory card in the phone (on which
phonebook data has already been saved) and you then remove the card, the Avaya 3711
will cease to operate until a programmed1 memory card is inserted. (The phone should be
equipped with memory card by default.)

Inserting the memory card

Important note on safety

Take great care handling the memory card. The contacts should be free of dust, grease and
moisture. Do not store your card in a place where it will get hot (e.g. through direct exposure to
sunlight). Avoid bending the memory card, as the contacts may get damaged.
1. Press the memory card out of the plastic frame using your finger.
1 A programmed memory card is a memory card that has already been used in a Avaya 3711 telephone.
