frequently as well as an activated vibration alarm are also decisive characteristics shortening the
standby and talk times. Another factor reducing the talk time is a low RTP package length that is
received by the other party.
Reach
WLAN handsets have a lower reach than firmly installed WLAN connections in a PC that are exclu-
sively designed for data traffic. This is due to the fact that in the data traffic, more package losses can
be tolerated than in voice operation. Thus note that a safe voice operation starts at a field strength
of approximately – 70 dBm to the AP. You can check the field strength to the APs in the site survey
display (see there). Causes for low reaches may be reinforced concrete walls, microwave devices,
obstacles, floor heatings, etc.
PIN protection
As in certain menus, wrong entries may cause failures of your telephone system, different system
settings are protected by means of a PIN. In the delivery state, the PIN is set to “22222”. Change the
PIN if necessary.
MEM card
The Aastra 312w is equipped with a memory card (MEM card). The local settings of the device
(among others a local telephone book with 100 entries) and the device identification (MAC address)
are saved on the MEM card. It is therefore possible to have this data available on another device
when devices are exchanged (by putting the MEM card into the new device), enabling you to call
immediately (without having to register again).
The MEM card is inserted into the battery compartment underneath the battery. For safety, an extra
battery compartment locking device is installed.
In some models, the MEM card is already installed. If the MEM card is supplied separately, you must
insert it into the battery compartment underneath the battery. Please read the section below
(Installation) to find out how to equip the Aastra 312w with the MEM card.
Headset connection
The handset has a 2.5 mm catch socket for the connection of a headset. Only the headset offered as
an accessory from Aastra can be used in order to maintain the electric values.
