Disposal

2005 -08- 13

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 %

Power Button

! Press and hold for 2 seconds to power on & off.

“OFF...” - Power Off

! 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 Message

! When “ERR” appears in the display it indicates

that an operational error has occurred. Please refer to the following codes to diagnose which error you are experiencing.

ERR no01 EEPROM is not being programmed or

internal data error.

ERR no02 For testing only.

ERR no03 The frequency you want to program is

above the switching bandwidth of the transmitter. Use a receiver with an appropriate frequency group. (At this time the microphone is still operating and the frequency remains unchanged. To clear the displayed "ERR" message, switch the handheld transmitter off and on again.)

ERR no04 The frequency you want to program is

below the switching bandwidth of the transmitter. Use a receiver with an appropriate frequency group. (At this time the microphone is still operating and the frequency remains unchanged. To clear the displayed “ERR” message, switch the handheld transmitter off and on again.)

! “Group” & “Channel” : When both the group

and channel numbers are displayed, it means that you are using the pre-programmed frequency of the receiver.

OFF...

! “Channel” Only : If “Channel” only is

displayed, it means that you are using a frequency which is not pre-programmed.

Caution

Note: Transmitter cannot be powered on with

charged battery.

Method 1:

a. Ensure battery is inserted correctly with + top

side.

b. If battery is inserted correctly it could be due

to self battery protection mechanism. Insert the transmitter into the charger to re-charge for 10-20 seconds to wake-up the battery. It should work.

c. If charger cannot be used, reverse the battery

insertion for 10-20 seconds, wake up the battery with correct polarity. It should work.

Method 2:

a. Power off the transmitter before open the

hinged cover. Press battery protection circuitry reset button once to wake-up battery. Power on the transmitter.
