13 Operation Notice
13.1 Accessibility and Voice Quality
The WLAN network is not always available. If you do not get in contact with your system, contact your
system administrator. For best voice quality, avoid positioning near computer, radio or similar equipment.
Operating Area
The handset can only be used in the area covered by the system. Outside of this area the handset looses
contact with the system. The signal strength icon is low and No network is displayed.
Out of Range (No Network)
When the handset leaves the system's coverage area, a short beep sounds and the text No network is
displayed. This can also be indicated with a vibrator (if enabled) and a dialog window (if enabled by the
system administrator).
The out of range beep is by default repeated every minute for 30 minutes. The sound can be turned off by
long pressing
, or the pressing mute button. It can also be set to indicate only once, or be turned off
completely, contact the system administrator.
Even if Indication off is set, the No network (or No access, which means that there’s neither voice, nor
messaging connection) dialog window (popup) still can appear as a completely silent indication. Contact the
system administrator.
When re-entering the coverage area it can take a couple of minutes before the handset is automatically
registered with the system.
13.2 Restricted Mode
To configure Restricted Mode, see the Configuration Manual, Ascom i63 VoWiFi Handset, TD
93300EN.
As a battery saving action, the handset can be configured to enter a Restricted Mode when the battery
voltage gets lower than a predefined threshold value set in mV. In that mode, no calls (including Push-To-
Talk and alarm calls) can be made or answered but WLAN positioning, alarm and messaging will still be
available. The handset will leave Restricted Mode when the battery is replaced or charged.
A short while before the battery voltage gets lower than the predefined threshold, the following warning
text will be displayed on the handset:
Battery is low. Restricted
Mode will soon be entered.
Calls will be terminated.
When the handset enters Restricted Mode, the above warning text will be replaced with the following text
that remains until the battery is replaced or charged:
Restricted Mode
Calls are not possible.
