User's Manual

Note:

An invalid entry is signalled by three brief signal tones, then the IB code

must be re-entered. After four invalid entries the unit deactivates itself

completely for 10 minutes. Not until the 10 minutes have elapsed can the

process be restarted (a brief signal tone sounds every 4 seconds).

5 Normal operation

During normal operation all the "normal" functions of the unit are activated,

whereby a distinction is made between the programming functions and the

operating functions.

5.1 Programming functions

Referred to here are the functions with which the operating functions can be

preset (programmed). The programming functions essentially differ from the

operating functions to the extent that before the actual numeric entry is made,

the "key" switch is pressed. In this connection it is assumed that any possible

phases from the operating functions have expired. This is always signalled by a

long signal tone. If there is any doubt about this, before making an entry, you

should wait more than 20 seconds without pressing any key.

Note:

Every press of a key allowed is acknowledged by a short signal tone; in

this way you can monitor whether the button was actually pressed. Fur-

thermore, between two presses of a key in succession, no more than 15

seconds may elapse; otherwise a long signal tone sounds and you then

can/have to start anew. In this way (simply wait for a long signal tone to

sound) an operation initiated by mistake can be aborted and started anew.

An invalid or incorrect entry is always signalled by three brief signal tones -

after which the unit completely deactivates itself for 10 seconds. You then

have to wait for a long signal tone to sound before the operation can be

started anew.
