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!

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.
