Preset
In Tune mode the user can select any frequency within the switching bandwidth of
the frequency table in 25kHz steps and then save them to the User memory. The User
memory is initially programmed with a copy of the Preset frequencies until the user
selects and saves a frequency in Tune mode.

Units which are programmed with multiple tables will show frequency table selection
on the menu. Entering the frequency table selection screen will show the frequency
table number. The user can select any one of up to 10 tables.

RF Power
In selecting the RF Power from the Sub-options menu the user can select High or Low
power settings. In selecting the low power setting the user will extend the battery life
of the transmitter.
Blue LED on/off
Selecting this option allows the user to turn the blue ‘On’ indicator LED, on or off.
The default setting is on.
AF Mute setting
Selecting this option allows the user to configure the On/Off button as a momentary
mute button. This might prove useful in an interview situation where the presenter
wants to keep the transmitter on, but wishes to turn the audio off momentarily.

function, but if the user wants to the turn the transmitter off the button just needs to be
held down for a longer period.

supplied settings then the user can use the restore function. Please note this will
overwrite any user memory settings and gain settings.

Batteries
Upon finishing with any used batteries please dispose of them as special waste. In
