If you find it impossible to turn off the instrument using the OPERATE button in units with a
Battery Option, hold OPERATE down and then tap RESET twice. Or you can simply hold the
OPERATE button down for five seconds.
1.7.4 Warranty
The FONIX FP40/FP40-D and its accessories are guaranteed to be free from manufacturing defects
which would prevent the products from meeting these specifications for a period of one year from

Battery pills are warranted for thirty days because they are necessarily fragile and can be damaged
by careless handling.
