Frequently Asked Questions About Keypad Function
 Can any of the switches be activated permanently?
Yes, the additional switch can be activated by one password and
deactivated by another.
 Is it possible to arrange for the switch to be activated during the
whole call?
Yes, additional switch can do it.
 Is it possible to use a single command to activate one switch first
and the other later?
Yes, it is possible to use parameter 824, Switch 2 delay.
 Can both the switches be activated at the same time?
While one switch is activated, the other can be activated by another
password. You can also use parameter 824, Switch 2 delay, defining the
shortest delay time possible (1second) and a sufficiently long switch
activation time.
 Can I use the code lock while another person is speaking through
2N® Helios? Yes but this is not advisable as you should be aware that
the password is private and could contravene security.
 What happens when I press a number with no pre-programmed
memory while the button replacing function is enabled? The same
as if you pressed a button that is not pre-programmed: 2N® Helios
seizes the line, beeps refusal (refer to Signalling) and hangs up
immediately.
 What happens if a password is identical with the memory number
while the code lock and button substituting functions are enabled?
The code lock function has the highest priority. If, for example, the
password is 33 and you press
, the switch is activated
instantaneously. If you press without an asterisk, the line is seized
after a preset delay and the number from memory 33 is dialled.
Password Selection Tips
 Keyboard letters facilitate password remembering. For example, it is
easier 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 a
considerable wear and tear of one button and an unauthorised person may
guess your password easily. It is ideal to employ all keys evenly, using
several codes for different persons or groups.
