Ringer Equivalence Number (REN)

Your euroset 835 has a REN of 1. REN is a guide to the maximum numbers of telephones that may be connected to a single exchange line. The sum of individual REN values connected to the exchange line should not exceed the total of 4.

Operation cannot be guaranteed in installations with mixed types of apparatus.

Power connection

Your euroset 835 must be operated with a mains voltage 230V AC, +6% -10%, 50Hz (indicated on the plug-in power unit).
For safety reasons, the euroset 835 telephone may only be operated with Siemens plug-in power unit supplied (C39280-Z4-C66).

If the equipment develops a fault

Not every malfunction means that your telephone has developed a technical fault. If the defect is a relatively simple one, you are likely to save both time and money if you can trace the cause of it yourself.

 

No dial tone on lifting the handset
Is the connecting cord inserted properly at the telephone and at the telephone jack?

 

A dial tone can be heard but dialing is not possible
The connection is in order.
The dialing method has to be set correctly (Link to sectionSetting the dialing mode).

 

The telephone does not ring
Is the ringer deactivated? Set the ringer.

 

Operation in connection with a PABX only
No connection or a wrong connection on dialing from the memory (speed dialing, redial).
Program the exchange code!

 

Loudspeaker cannot be switched on
Is the plug-in power unit connected properly?

 

Answering machine does not function
Is the plug-in power unit connected properly?

 

The telephone does not respond to pressing of keys
Replace the handset and lift it again.
If this has no effect, disconnect the plug-in power unit briefly and then reconnect it.

 

Another possibility is that you have too many phones plugged in. Or perhaps you have a fax machine or answering machine plugged in too. This is important because your telephone line only has a small amount of electricity running through it to make your phones ring, so it may be necessary to limit the number of phones or other pieces of equipment you have connected to your telephone line.

 

To help you, every phone has what is called a Ringer Equivalence Number (REN), which is shown on a label underneath the phone. In most cases a standard line should provide enough current for two or more phones whose REN’s add up to no more than 4. Your euroset 815 has a REN of 1.
