Battery safety

Only use the rechargeable batteries supplied with the
handset. DON'T use non-rechargeable batteries —
they may burst, causing damage.
Connection You can connect your e820 to a direct exchange line
and conditions
(DEL) — a line connected to a local exchange, with its
for use
own phone number; to an extension socket connected
to a DEL; or to an extension on an approved compatible
PBX. Do not connect the e820 as an extension
to a payphone.
The ringer equivalence numbers (RENs) of all
instruments (phones, fax machines, etc.) connected to
an exchange line must not add up to more than 4 —
otherwise, one or more of them may not ring and/or
answer calls correctly. The e820 has a REN of 1, and
most other telephones have a REN of 1 unless marked
otherwise.
