EnGenius DuraFon 1X Quick Reference Sheet page 3

How do I transfer a call from an EnGenius Handset to a different extension off my PBX phone
system?
Most PBX transfers will require you to PRESS the FLASH (green button) key + an extension number, then the "END"
(red button) to complete the transfer. An exception is Nortel, which requires you to PRESS FLASH, Star (*), 70 + an
extension number, then "END".
How do I register handsets to multiple DuraFon 1X Base Stations?
See the DuraFon 1X Quick Reference Sheet on registering to multiple Base Stations.
Can a 1X handset work with a 920, 4x, or PRO base unit?
No. DuraFon 1x is not compatible with any other systems.
Will my external antenna from my older EnGenius phone still work with my new 1X?
Yes. Our reverse thread TNC connector on the base is the same on ALL EnGenius telecom products.
Can I answer a second call coming through a secondary Base Station while on a call with an initial Base
Station?
No. The DuraFon 1X handset can only utilize one connection at a time. Using the Telephone service provider's "Call
Waiting" feature, and pressing our "TALK/FLASH" key is the only way to answer a second inbound call can be
received. If you need this capability, we suggest using the multi-line system DuraFon PRO.
Will my DuraFon 1X Base Stations interfere with each other or other communication devices?
Yes, Base Station units and/or the High Gain antennas should be at least 30' apart from each other, and other
electronic equipment for best performance and to reduce interference.
Does my DuraFon 1X have built in Voice Mail?
No.
Will my DuraFon 1X hand off a call as I walk into a second Base Station zone?
No, there is no handoff capability. If using our system behind a PBX/Key System you can transfer to the 2nd bases
extension number and pick up after you release from original connection.
How can I tell the different between a DuraFon 1x, 4X, PRO, and DuraWalkie Handset?
The DuraFon 1X handset has a black bezel around the LCD, the DuraFon 4X has a silver bezel, the DuraFon PRO
has a green bezel, and the DuraWalkie has a blue bezel. Additionally, you can remove the battery and see the model
on the serial number label.
Does the DuraFon 1X Handset have speakerphone?
Yes and No. All phones built after Nov. 2007 with serial number 07A101340 or higher will now include this feature.
Does a DuraFon 1x support Call Waiting, and/or 3-Way Calling?
Yes, provided this is handled by the phone company or phone system it is connected to. You will need to PRESS the
FLASH key to flip between callers. The green "talk" key is the flash key.
On what frequency does the DuraFon 1X operate, and will it interfere with Wi-Fi networks?
The DuraFon uses frequency hopping spread spectrum technology at 902 to 928MHz. Wi-Fi networks operate in
either the 2.4GHz and/or 5GHz frequency spectrums – a non-overlapping and non-interfering frequency; as a result
EnGenius DuraFon systems will not interfere with Wi-Fi networks.
Why use 900MHz, when it is an older technology compared to newer 2.4 and 5GHz cordless frequencies?
900MHz range is actually much greater than the range higher frequency 2.4 and 5GHz cordless phones. Lower
frequency signals like 900MHz are less absorbed by objects and less affected by walls, buildings, trees, and even
open air. Additionally, 900MHZ phones avoid Wi-Fi networks altogether, thus avoiding interference from 2.4 or 5GHz
signals. Finally, the FCC allows more power to be used for lower frequency devices like EnGenius DuraFon products
which additionally helps boost and extend operational range.
When was my phone manufactured?
The first three values in the serial number determine build date. The first two are the year, and the third digit is the
month, where A = Oct., B = Nov., and C = Dec. For example 07Cxxxxxx = 2007, December.
