Q12. What is the manufacturer's warranty?

A12. One-year limited warranty.

Q13. What factors affect range of radio wave transmissions?

A13. Many environmental factors may interfere with radio wave transmissions. Some of the more common factors include: trees, buildings, hills, walls, temperature, humidity, other radio transmissions and other obstacles.

Q14. What can be done to maximize the range performance?

A14. By removing as many obstacles as possible and placing the base and / or antenna as high as possible will enhance the range. Maintain as much line-of-sight transmission as possible.

Q15. Has the EnGenius Industrial Cordless Phone System passed all the regulatory and safety testing?

A15. Yes, The EnGenius Industrial Cordless Phone System passed all the regulatory and safety testing for the U.S. and Canada.

Q16. Is the range the same from the base to handset as from handset to handset?

A16. The same transmitter and transmission power is used in both the handset and the base.

Q17. How far should the base unit and the antenna be placed apart?

A17. For best results, keep 10 - 15 feet between other antennas and/ or electrical equipment.

Q18. If my base has multiple handsets, can I make two-way radio transmissions while someone is making a cordless phone call?

A18. Yes, the two-way radio transmissions are completely independent of the base. So, in fact you could take several handsets to a remote area away from the base and have two-way radio conversations between the handsets.

Q19. At such high power how do you get your battery to last up to four hour of talk time?

A19. The EnGenius handsets utilize an advanced power management system to transmit at onl;y the power needed to produce and maintain a clear signal. We transmit at between 80 and 630 milliwatts in one-fifteenth increments.

Q20. Why do you include two antennas (long and short) with each handset?

A20. Some people prefer the convenience of the short antenna and other people prefer to maximize the range with the long antenna which will provide approximately 20% more range in an open area.

Q21. How many handsets can be transmitting without incurring interference?

A21. We conducted two test in various size rooms: Test A: Room size: 25 feet x 15 feet - we first experience interference when the 14th handset or 7th simultaneous radio link was established. Test B: Room size: 30 feet x 30 feet - we first experienced interference when the 26th handset or 13th simultaneous radio link was established.
