DHTRQUAD System

Thank you f or purchasin g the DHTRQ UA D wireless sy stem. For u se rs who ne ed an advanced UHF wireles s system, the DHTRQUAD provides an e xc ellent sol ution. With 120 selectab le channe ls , th e DH TR QUAD is perfect for appli ca tions such as live shows, broadca st , me et ings, & musical instrum en ts . Touch buttons and liquid crystal displ ay s al low for a qu ick and simple system set up . The "User Guide"a nd " Quick Se tt ing Gu id e" inclu de d in yo ur syste m will pr ovide al l the d et ails you need t o operate the s ys te m effic ie ntly.

Frequency Band

Most countr ie s closel y regula te the radio freque nc ies us ed in the t ransmissi on of wi reles s in forma ti on. These r eg ula ti on s sta te which de vi ses c an u se whic h frequenci es , a nd help to limit th e a mount of RF (r ad io frequency ) i nt erference in al l wireless c ommunicatio ns . Th e DHTRQUAD offers 1 20 selectable cha nn els within either the 58 4- 60 7MHz (Code D) o r 65 5-679MHz (Cod e L) f requency rang es .

To fa cilitate sys te m s etup and protect aga in st RF interferenc e, ea ch system comes with multiple predefined frequency groups an d channe ls . When using a single receiver/ tr an smitter, the oper at ing freq ue ncy will generally not ha ve to b e changed. In an installatio n with multiple receivers/t ra nsmitters , each set must operat e on a separate channe l from the o th ers. The group and channel syst em provides an optimum fre qu en cy spread whe n us ing multiple re ce iver/tran sm it ter systems .

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.

The 3 position Squelch Adjustment helps to prevent extraneous RF from being picked up and turned into audio when the transmitter is off. The higher level will reduce the useable distance of the transmitter from the receiver. Use the lowest setting to keep the receiver quiet when the transmitter is off.

Troubleshooting

Tips for Improving Sys te m Performance

Maintain a line of sight between transmitters and anten nas.

Avoid p lacin g the receiver near metal surfaces or any digital equipment (CD players, computers, etc).

Keep the receiver away from the wall and at least 1m from the ground.

Cellular telephones and two-way radios can int erfer e with th e opera tion of w irele ss syst ems.

Do not use these devices in close proximity to the wireless system s.
