TYPE ON HANDHELD MICROPHONE
Battery Life Indicator
The battery low indicator lights red
when the battery charge is low.
Battery Type
The transmitter will operate with
either standard AA alkaline batteries
or nickel metal hydride (NiMH)
rechargeable batteries. Since these
types of batteries have different
characteristics, it is important not to
mix battery types. Use only AA NiMH
batteries when recharging.
NOTE: Do not mix battery types.
WARNING: Do not use NiCad
batteries! They will not charge
properly and may cause damage to
the transmitter.
Lightspeed recommends Panasonic
or Energizer batteries. Duracell may
not work.

charge alkaline batteries. They can
overheat and expand, creating a
significant hazard and damaging the
transmitter. (This is not covered by
warranty.)
1. Switch the transmitter power OFF.
2. Insert the small DC plug into the
jack on the bottom of
the transmitter.
3. Plug the other end of the charger
into any standard 110 VAC outlet.

impedance source, such as a guitar,
it will be necessary to adjust the GT
dial. Using a high impedance source
requires a special cable. Contact
Lightspeed Customer Service at 800-
732-8999 for more information.
Gain Adjust:
When changing microphones or
users, it may be necessary to adjust
the transmitter gain based on
differing microphones sensitivities
and voice levels.
To adjust the gain:
1. Open the battery compartment
door by depressing the latches on
each side of the transmitter.
2. Turn the MT dial clockwise
to increase the gain and
counterclockwise to decrease the
gain.
