Telephones 10200AR each have a Ringer Equivalence Number (REN) of 1.
A telephone with a REN of 1 has a ringer sensitivity similar to that of a standard

To convert from earth loop to timed break recall, remove telephone cover and carefully, shift
both links from positions a-b to b-c.
Telephones 10200AR are supplied with batteries that should last at least 12 months, to
power the memory and display circuitry. The battery should be replaced when the `battery
low' indicator shows up momentarily or if the telephone gives a short bleep as the handset
is lifted. Low batteries will also result in the display appearing faint when the handset
is replaced after a call.
The telephone should be disconnected from line when batteries are being replaced. This
will result in loss of stored numbers and resetting of clock and alarm facilities.
