Can both the switches be activated at the same time?While one switch is activated, the other can be activated by anotherpassword. You can also use parameter 824, Switch 2 delay, defining theshortest delay time possible (1second) and a sufficiently long switchactivation time. Can I use the code lock while another person is speaking through2N® Helios? Yes but this is not advisable as you should be aware thatthe password is private and could contravene security. What happens when I press a number with no pre-programmedmemory while the button replacing function is enabled? The sameas if you pressed a button that is not pre-programmed: 2N® Heliosseizes the line, beeps refusal (refer to Signalling) and hangs upimmediately. What happens if a password is identical with the memory numberwhile the code lock and button substituting functions are enabled?The code lock function has the highest priority. If, for example, thepassword is 33 and you press , the switch is activatedinstantaneously. If you press without an asterisk, the line is seizedafter a preset delay and the number from memory 33 is dialled.Password Selection Tips Keyboard letters facilitate password remembering. For example, it iseasier to remember a 9-letter word (e.g. crocodile) than a 9-digit number(276263453). It is not recommended to use such passwords as 3333. This leads to aconsiderable wear and tear of one button and an unauthorised person mayguess your password easily. It is ideal to employ all keys evenly, usingseveral codes for different persons or groups.
