Disposal

2005 -08-1 3

Dispose of any unusable devices or batteries responsibly and in accordance with any applicable regulations.

Disposing of used batteries with domestic waste is to be avoided!

Batteries / NiCad cells often contain heavy metals such as cadmium(Cd), mercury(Hg) and lead(Pb) that makes them unsuitable for disposal with domestic waste. You may return spent batteries/ accumulators free of charge to recycling centres or anywhere else batteries/accumulators are sold.

By doing so, you contribute to the conservation of our environment!

Battery Status

Indicates the power remaining in the transmitter battery. When the battery has less than 10% power remaining it must be replaced or recharged. If an under voltage condition continues, the LCD will show “OFF...” and the system will shut down to prevent being overly discharged.

10 0% 80 % 60 % 40 % 20 % 10 %

“OFF...” : Power Off

1. Press and hold power button for 2 seconds to

power on & off.

2. When the power switch is turned off, the LCD

will show “OFF…” (for Power Off) first and then

the system will shut down and no further

messages will be displayed.

ERR: Error Code

If the LCD displays “ERR” after turning on the power, it indicates the operation is not correct. The error codes are as follows:

ROM-ER → Transmitter does not have the initial

data so the microphone is completely dead and cannot be programmed.

ERROR1 → Failure on RF circuitry, frequency

cannot be programmed.

NO----OR3 → Frequency to be programmed into

the transmitter exceeds the highest frequency of the designated frequency band of the transmitter.

NO----OR4 → Frequency to be programmed into

the transmitter exceeds the lowest frequency of the designated frequency band of the transmitter.

**Note:

NO----OR3 and NO----OR4 will not change the

transmitter's original frequency and the

transmitter will still operate normally with the

error message on display. To remove the error

message from the display panel, please switch

off the transmitter and switch it on again.

High Frequency Bypass

a. When other microphones are in use, some

changes may be needed to another microphone before adding it to the system in order to avoid high frequency interference, as illustrated in diagram (1).

b. When a high frequency radio wave causes

interference, it normally affects the system by generating a persistent noise or by deteriorating the frequency response. In an effort to ameliorate these problems, a 330PF bypass condenser can be added on the cartridge as shown in diagrams (1) and (2). If this method is not possible, another option is to add a bypass condenser on the 4-pin XLR connector as shown in diagrams (3) and (4).

**The Best Method

(1) Connect to two-wire condenser capsule

**Alternate Method

(3) Connect to two-wire condenser capsule

open battery compartment cover. Take out the

two batteries. (Figure 3)

! Insert two fresh AA batteries (alkaline type is

recommended) into the battery compartment

according to the correct polarity (- and +) as

shown in (Figure 4). Then close the battery

compartment cover tightly.

! Then the other side of the belt

clip can be departed from the other slot easily. The whole belt clip is departed from the bodypack transmitter completely like the right diagram.

Assemble the Belt Clip

! Turn the bodypack transmitter

to the back side. Put the belt

clip to the right direction and

aim the one side of the belt

clip to the slot of

the bodypack

transmitter like

the right diagram.

transmitter, just rotate the belt

clip by 180℃ like the right

diagram.

! Put one side of the belt clip to

the slot of bodypack

transmitter and fix it like the

right diagram.

! Pull open the other side of the

belt clip and put it to the

other slot of bodypack

transmitter and fix it like the
