Battery supply
The standard battery supply consists of 2 identical battery packs with each
pack containing 2 Lithium batteries connected in series. The operating
voltage is 7,2 Vdc. The battery pack that is connected to connector 1.1 will
be used first for the modem and the battery pack that is connected to
connector 2.2 will be used for the internal clock. After pack 1.1 is
consumed it will switch to pack 2.2. For certain applications additional
battery packs can be applied. These will be connected to connectors 1.2;
1.3 and/or 1.4.
An additional pack can be connected to connector 2.1 for extended back-
up.
