Battery installation & indicator
This belt-pack requires 2 x AA batteries to operate.
To install, open the battery cover using the cover release buttons and insert the batteries into
the battery compartment.
Note: Batteries contain a corrosive acid that may leak and damage the belt-pack when stored
for a long period. Batteries should be removed from the belt-pack before storing without use for
more than 4 weeks.
When the transmitter is switched ON, the battery power LED (red) will blink once to indicate the
batteries installed are in good condition. If the LED remains illuminated the batteries have
expired and require replacement.

the use of instrument with high impedance, such as guitar while MT is for the use of low
