Environment

Your Converse 120 should be kept free of dust, moisture and high temperatures.

Wipe the casing clean with a damp, not wet, cloth.

Do not use spray or abrasive cleaners as damage to the internal components or polished surfaces could result.

How many phones

can you have? (REN)

All items of telephone equipment have a Ringer Equivalence Number (REN), which is used to calculate the number of items which may be connected to any one telephone line. Your Converse 120 has a REN of 1. A total REN of 4 is allowed. If the total REN of 4 is exceeded, the telephones may not ring.

With different telephone types there is no guarantee of ringing, even when the REN is less than 4.

Connection information

Your Converse 120 may be connected to public networks in the United Kingdom.

It may also be connected to switchboards providing Pulse or Multi-Frequency (MF) signalling and Timed Break or Earth Loop Recall facilities. If in doubt, your switchboard supplier or maintainer should be able to offer help. Advice on connection to BT switching systems can be obtained by calling Freefone 0800 800 154.

It can be connected to Meridian systems with Message Waiting.

The Message Waiting Indicator responds to the series of line reversals output by the Meridian.

If you do not have a compatible switchboard, it cannot be guaranteed that your Converse 120 will operate correctly under all possible conditions of connection.
