DHTRQUAD System

Thank you for purchasing the DHTRQUAD wireless system. For users who need an

advanced UHF wireless system, the DHTRQUAD provides an excellent solution.

With 120 selectable channels, the DHTRQUAD is perfect for applications such as

live shows, broadcast, meetings, & musical instruments. Touch buttons and liquid

crystal displays allow for a quick and simple system setup. The "User Guide"and"

Quick Setting Guide" included in your system will provide all the details you need to

operate the system efficiently.

Frequency Band

Most countries closely regulate the radio frequencies used in the transmission of

wireless information. These regulations state which devises can use which

frequencies, and help to limit the amount of RF (radio frequency) interference in all

wireless communications. The DHTRQUAD offers 120 selectable channels within

either the 584-607MHz (Code D) or 655-679MHz (Code L) frequency ranges.

To facilitate system setup and protect against RF interference, each system comes

with multiple predefined frequency groups and channels. When using a single

receiver/transmitter, the operating frequency will generally not have to be changed.

In an installation with multiple receivers/transmitters, each set must operate on a

separate channel from the others. The group and channel system provides an

optimum frequency spread when using multiple receiver/transmitter systems.

Battery Status Indicators for both the Handheld and Bodypack

Transmitters feature Four Level Displays.

Group and Channel Display:

After completing the ASC, both the Handheld and Bodypack

Transmitters will display the Group and Channel numbers selected.

Normal Display:

Both Handheld and Bodypack Transmitters will display Group and

Channel numbers as well as Battery Status.

Setting up multiple receivers

1) Power on any pre-existing wireless systems and transmitters except the first DHT system.

2) Power on the first DHT Receiver.

3) The Control and set buttons are on the front of the receiver.

4) Press the set button until the group number flashes on the LCD screen

5) Press the up/down buttons to select group 1.

6Press the set button twice to get to the scan mode.

7) Press the up or down button. The unit will now go into scan mode. You will probably see the RF

meters light up if the scan sees other transmitters.

8) When it stops scanning, it will stop on the clearest frequency, and will be flashing the frequency

on the LCD screen.

9) Press the set button and it will set itself to that frequency. Do not wait to press the set button as

the DHT Receiver will revert back to the original frequency, and the process will need to be restarted

10) If the unit cannot find a good frequency within group 1, start the process again scanning

group 2, if that is also not clear try group 3, and so on till you get a good frequency.

When the DHT Receiver has been set to a clear frequency, use the ASC feature to sync the

receiver frequency to the transmitter.

11) Turn the transmitter on, aim the red infrared window on the transmitter towards the one on

the receiver and press the ASC button on the front of the receiver. The transmitter will sync to

the receivers frequency.

If you have more DHT systems to tune follow the same procedure on each one, always leaving

the previous system transmitter on.
