Trouble teaching DHT-T100 remote control commands
• Make sure the source remote is working properly in the first place; check batteries; confirm direct operation.
• Move the DHT-T100 and source remote out of bright sunlight or powerful room lighting (too-bright light will impede
infrared-signal transmission).
• Be sure to hold the “source” remote steady, 0.3-0.5m in front of the DHT-T100, on its level, with the remote’s
IR emitter
(usually a smooth black-plastic area across the end you point toward the television) aimed straight
and level at the center
of DHT-T100’s front panel.
• Press and release source-remote keys deliberately; hold each keypress down for a half-second or so, and pause a
second between repetitions.
• Remember that while DHT-T100 can learn almost all IR (infrared) remote commands, there remain a few rare code
formats that cannot be taught (much like some engineers we know).
Television speakers keep getting turned back up
• Disable the television’s speakers (usually a setup-menu option, but a rear-panel switch on some televisions). If this is
not
possible, the problem is likely that the television responds to press-and-hold (ramping) volume commands more
quickly
than the DHT-T100; in this rare case use DHT-T100’s front-panel or supplied remote to turn the DHT-T100's
volume up.
Trouble Pairing Bluetooth®
• Make sure DHT-T100 is in Bluetooth pairing mode (Bluetooth key LED should be flashing).
• Make sure your Bluetooth source is in Bluetooth pairing mode (see the source’s instructions).
• Bluetooth source device must support A2DP (Advanced Audio Distribution Profile); some Bluetooth products (some
tablets, some GPS units, for example) will thus work with Bluetooth keyboards or headsets but are not capable of
high-fidelity audio playback.
• Keep your Bluetooth source within 3m of DHT-T100 while pairing.
• Power cycle the Bluetooth device (complete power off and “hard-reboot”), and try to pair again.
Bluetooth connection problems
• If a Bluetooth fault occurs (the device moves out of range, or stops playing due to low battery or user input),
DHT-T100’s Bluetooth LED again blinks rapidly; the DHT-T100 will automatically attempt to re-connect, and will resume
playback when the Bluetooth source is in range. Note: On some devices you will need to press play again. Bluetooth’s
effective wireless range varies with the source; (9-12m) is typical. If the source moves out of range, DHT-T100 will con-
tinue trying to re-connect it for 4 minutes; after that interval you will have to re-connect, as above.
• Make sure DHT-T100 is not paired to a different Bluetooth source device.
• Make sure your desired Bluetooth source device is actually playing music or another audio program and is paired to
DHT-T100 and not some other device.
• On a multifunction source device such as a tablet or mobile phone, not every program or “app” may support Bluetooth
audio broadcast (consult the instructions for the program or app).
• Consider possible sources of interference, particularly those operating at 2.4 GHz (Wi-Fi routers, microwave ovens, land-
line cordless telephones); power down suspects one at a time to identify a culprit. Often, repositioning an interfering
device to another room, or even across the room, will restore Bluetooth function.
DHT-T100 takes several seconds to turn on
• The DHT-T100’s power saving design puts the unit into standby mode after five minutes of no sound. DHT-T100 takes a
few seconds to start up the next time audio plays
Factory reset
• Unplug unit from wall.
• Hold down Vol
_
(minus) button.
• Plug into power again.
• Standby button light will blink fast for several seconds indicating that the system has been reset.
• Clears Bluetooth pairing, remote learning, audio mode.
