Widex TV-DEX Technical Tips

TV-DEX QUESTIONS & ANSWERS
Q: Is the TV-DEX Remote required to be turned on for matching
to hearing instruments?
A: No. The TV-DEX Remote must remain off for matching to hearing
instruments. If the TV-DEX Remote is turned on, matching will
fail. Follow the instructions in Compass and press the volume up
and down buttons simultaneously when told to do so.
Q: Can multiple Widex hearing aid wearers share one TV-DEX
Base and Remote? For example, a husband and wife each have
DREAM440 hearing instruments and want to watch TV together.
A: No. Both hearing aid wearers must purchase their own TV-DEX
System. Communication between the TV-DEX and Widex wireless
hearing instruments is done on a secure channel that is coded by
the TV-DEX Remote serial number obtained during the matching
process. A Y-cord will have to be purchased from an electronics
store to split the signal from the TV to each TV-Base.
Q: Is a TV-DEX System required for each TV in the house? For
example, a TV in the main room and one in the bedroom.
A: No. The hearing aid wearer can purchase one TV-DEX System,
with additional TV-DEX Bases. A purchase of one TV-DEX Base
for each additional TV will be required to use with televisions in
other rooms. The TV-DEX Remote is taken from room to room and
used to transmit to the hearing instruments. After changing rooms,
place the TV-DEX Remote into the TV-DEX Base for approximately
5 seconds to pair the TV-DEX Remote to that room's TV-DEX
Base. Once paired it is used as normal (see picture below).
Q: What standard mini-jack connector is used for personal audio
device input?
A: 3.5 mm (1/8")

Q: Which sound source is the default sound source when both TV
and audio input is used?
A: The On/Off button toggles through the input marked TV first,
then the Audio input and then Off in a sequence.
Q: What is the Room Off button on the TV-DEX Remote?
A: When this feature is activated, the
hearing aid microphones are shut off so
the user is not disturbed by background
noise or conversation while listening to
the television.
Q: What do the green and red lights on the buttons on the
TV-DEX Remote indicate?
A: A green light will appear on the On/Off button and a red light
will appear on the Room Off button. They indicate the various
states as below:
Constant green: transmission on
Alternating from green to red: transmission off
Constant red: Room Off active
Flashing red and green: battery charging
Flashing green: transmission
Q: How do I tell if a TV-DEX Remote is fully charged and how long
does it take to charge?
A: The green and red lights will flash when a TV-DEX Remote is
charging. The lights will stop flashing when the TV-DEX Remote
is completely charged. If the TV-DEX Remote is completely
discharged, it will take approximately 4 hours to fully charge at
which time the lights will stop flashing.
Q: How many hours of use on should be expected on a full charge?
A: Approximately 10 hours of transmission.
Q: Is there any danger in leaving a fully charged TV-DEX Remote
in the TV-DEX Base?
A: No. The charging circuit has built-in over-charging protection.
In fact, it is best to leave a fully charged TV-DEX Remote in the
TV-DEX Base to maintain the charge.
Q: What type of batteries does the TV-DEX take?
A: The TV-DEX uses a built-in rechargeable battery.
