Preliminary Safety Information 911 Emergency ServiceWhen a Tel-Lynx user places a 911 emergency call, Tel-Lynx will override theDo-Not-Disturb feature and switch into Ring-through mode, allowing all callsdirectly through for one (1) hour8. This ensures that returned emergency calls getthrough without delay. When the emergency is over, at the dial tone, you canpress # 6 # to cancel the override feature.When a user makes an emergency call, Tel-Lynx will select an available outsideline based on the user-defined shared outside line calling table for emergencycalls, unless the user specifies a line before dialing 911 (see Selecting anOutside Line).It is imperative that the emergency calling table is setup correctly;otherwise you may not be able to place an emergency call at a critical time.As of this printing, Skype™ does not provide 911 emergency call servicesfor the US; therefore, you should NOT use Skype™ as an outside line foremergency calls. By default the emergency calling table is setup to dial out firston the landline if it is available, then on mobile phone 1 if it is available, then onmobile phone 2 if it is available.If you change the default emergency calling table setting and specify Skype, youshould specify it as the last line to try when all others fail. You can program aphone number that Skype™ will call when you dial 911 on a Skype™ line.Be sure to program an appropriate phone number for your area. Power InterruptionsIf the power is out or Tel-Lynx is not operating for any reason, no calls, noteven emergency calls, can be placed or received through Tel-Lynx. If thishappens, you can call 911 directly on your mobile phone, or, if you have aTelco line, you can connect a wired telephone directly to it to call 911.Remember that most cordless telephones cannot be used when the poweris out.It is highly recommended that you put your cordless phone base stationand Tel-Lynx on a UPS (uninterruptable power supply) to avoid serviceinterruptions during power outages.It is also safe practice to place a wired telephone in parallel with Tel-Lynxon your landline (if you have one) so that the wired telephone can be usedin an emergency when the power is off. You can silence the ringer on the8 The call to 911 must last for at least 10 seconds in order for Tel-Lynx to switch into ring through mode.This avoids accidental 911 calls from switching modes.Copyright 2013-2015, nVideon, Inc.
