Battery Life

Maico recommends using 2 AA Alkaline batteries.

Batteries will last approximately 30,000 tone

presentations. The MA 1 has an automatic shut-off

feature to prolong battery life when unit is not in

use. When batteries get too low to produce the

proper signal, the unit will shut off and will not turn

back on until batteries are replaced.
