General FAQs

Can a 1x handset work with a 920, 4x, or PRO base unit?

No. 1x is not compatible with any other systems.

Can I answer a second call coming through a secondary base while on a call with an initial base?

No. The DuraFon 1X handset can only utilize one connection at a time. Outside of the Telephone service provider's "Call Waiting" the only way to answer a second inbound call is to be free to connect. If you need this capability, we suggest using our multiline systems (DuraFon 4x and PRO)

Programming FAQs

How do I register a new DuraFon 1X handset to a base unit?

To register a new DuraFon 1X handset to a base unit, please follow the following instructions:

  1. Power the base unit
  2. Power the handset to be added
  3. On the handset, press MENU - 6
  4. On the Durafon 1X base unit, press and hold the REG button near the telephone line jacks
  5. All the LED lights should light up when registration mode is entered
  6. On the handset, press 1
  7. Handset will indicate successful registration and handset ID will have been assigned
  8. Press END to exit to main menu

How many handsets will each DuraFon 1X base unit support?

The EnGenius DuraFon 1X system will support 9 handsets per base.

Troubleshooting FAQs

How can the range be maximized?

Range depends upon the environment, but below are some guidelines:

  1. 12 floors in building penetration
  2. 250,000 sq. ft. in a warehouse or retail store
  3. 3,000 acres on a farm or ranch

The range can maximized by:

  1. Mounting the terminal base antenna as high as possible and away from obstacles.
  2. An external base antenna can be used to provide coverage outside or to get above obstacles.
  3. The optimal performance, tall handset antenna will provide about 20% more coverage than the low profile, stubby antenna.
  4. If using an external antenna, be sure the antenna is mounted high and away from other antennas and obstacles. Be sure any remaining coaxial cable is un-coiled and laid flat in large 6 - 8 foot loops.

What is the battery life?

DuraFon 1X battery life:

Talk-time: 6 hours
Stand-by time: 50 hours
Lifetime cycles: 400 (about 1 year)

Battery time is based on distance between the two transmission / reception devices and will vary greatly.

Use of the tall fixed antenna may reduce the amount of power required to make or receive a transmission.
